Lallemand | Go-Ferm Protect | Yeast Rehydration Nutrient
A new, advanced formulation of Go-Ferm Go-Ferm Protect is a natural yeast nutrient that is added to the yeast hydration water before adding your selected yeast strain. Its complex formula provides your yeast with the proper sterols, unsaturated fatty acids and micronutrients needed to begin fermentation in optimal shape. The great thing about Go-Ferm Protect is that the proper nutrients and vitamins are introduced BEFORE the yeast is added to the must. This way 100% of the nutrients are available to your selected yeast strain and won't be stolen away by any indigenous yeast or bacteria that may be present in the must before your yeast can become established. Go-Ferm Protect was created as a result of a multi-year study of problem fermentations by Lallemand and the National Agricultural Research Institute (INRA) in France. During this period, they looked at the adverse effects on the yeast from overripe fruit (>28 Brix), low nutrient levels, overclarification of the juice and poor fruit quality (Botrytis, rot, high bacteria count, insecticide and fungicide residue). Their research showed that musts deficient in sterols and unsaturated fatty acids made yeast more susceptible to ethanol toxicity (high alcohol), osmotic shock (high sugar), temperature and others stress factors. In response to this data they created the NATSTEP (NATural STErol Protection) process that incorporated sterols, unsaturated fatty acids, as well as vitamins and minerals into an advance yeast hydration nutrient: Go-Ferm Protect. Go-Ferm Protect provides a combination of protective and nutritional benefits that ensure your yeast begins your fermentation in peak form! The best part is that if your fruit is in great shape then Go-Ferm Protect will simply help your yeast out that much more! Go-Ferm Protect does not contain any DAP, as DAP is harmful to the yeast during the rehydration process. GO-Ferm is usually used in conjunction with our Fermaid K yeast nutrient; where Go-Ferm Protect is used at yeast hydration then Fermaid K is added at the first signs of fermentation and again after 1/3 sugar depletion. Use: Use at a rate of 1.25 g Go-Ferm Protect per 1 g of yeast. A rough approximate of weight is 1 tsp = 3.2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates. Download the PDF Like Go Ferm Protect? Then you will love CellarScience® FermStart!

Lallemand Fermaid K | Yeast Nutrient for Strong Fermentations
Fermaid K – Complete Yeast Nutrient for Strong, Clean Fermentations Provides a balanced blend of organic and inorganic nitrogen to support vigorous yeast growth Delivers consistent fermentation kinetics and helps prevent sluggish or stuck ferments Reduces the risk of off-aromas such as hydrogen sulfide by supporting healthy yeast metabolism Enhances fermentation security, especially in high-sugar musts or stressful conditions More immediately available YAN than Fermaid O due to its inclusion of diammonium phosphate (DAP) Fermaid K is a widely used yeast nutrient developed by Lallemand to support strong, reliable alcoholic fermentations. It contains a combination of inactivated yeast (for organic nutrients) and diammonium phosphate (DAP) to supply both slow- and fast-release nitrogen. This dual-action profile provides yeast with the nutrients they need throughout the growth phase and active fermentation, improving cell viability, reducing fermentation stress, and minimizing the formation of undesirable sulfur compounds. Fermaid K is especially effective in fermentations that begin with low YAN, high sugar content, or other challenging conditions that demand immediate nitrogen availability. Fermaid K contributes approximately 1 ppm of measurable YAN for every gram per hectoliter used. That means: 1 gram per liter adds 100 ppm of YAN 1 gram per gallon adds approximately 378 ppm of YAN In comparison, Fermaid O contains only organic nitrogen and provides about 0.4 ppm measurable YAN per gram per hectoliter, or 40 ppm per gram per liter, and 151 ppm per gram per gallon. Fermaid O is preferred for slower, more controlled fermentations or when avoiding inorganic nitrogen is important. Fermaid K is ideal when rapid yeast growth and fermentation speed are critical. Protocol Rehydrate yeast first, then add Fermaid K at the end of the lag phase (typically around 24–48 hours after inoculation or at approximately 1/3 sugar depletion). Suspend in 10 times its weight of clean must or water, stir thoroughly, and add to the fermenting must with adequate mixing. Avoid adding at the same time as sulfites or enzymes. Usage Rates Recommended dosage: 20–40 grams per hectoliter = 0.2–0.4 grams per liter = 0.76–1.5 grams per gallon Adjust dosage based on initial YAN content, fermentation conditions, and yeast strain requirements. Use higher rates in low-YAN musts or high Brix ferments to maintain healthy yeast activity throughout. Comparing the Yeast Available Nitrogen contribution of Fermaid K vrs Fermaid O If you add 1 gram per liter of Fermaid K, it contributes 100 ppm of YAN. If you add 1 gram per gallon of Fermaid K, it contributes approximately 378 ppm of YAN. If you add 1 gram per liter of Fermaid O, it contributes 40 ppm of YAN (Yeast Assimilable Nitrogen). If you add 1 gram per gallon of Fermaid O, it contributes approximately 151 ppm of YAN. A rough approximate of weight is 1 tsp = 4.7 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Potassium Metabisulfite
Potassium Metabisulfite, (often referred to as "SO2", "sulfites" "meta", or "meta-bi") has several uses in winemaking. At the crush, sulfites are generally used to help control the spoilage bacteria and indigenous yeast that may already be present both on the fruit and in the winery (i.e. on the picking bins, processing equipment, tanks, tubing, etc). The amount generally used is enough to inhibit most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites than most of the indigenous organisms do. This inhibition effectively "wipes the slate clean" for the cultured yeast to step in and rapidly colonize the must so that it can effectively dominate the subsequent fermentation. In addition, sulfites also help to inhibit the enzymatic browning of both musts and finished wines so that all of their delicate complexities can be preserved. Later, during storage and in the bottle, sulfites at the proper levels will further protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen. Note that the exact amount needed to effectively do the job is determined by the pH of the wine. Refer to our MoreManuals! on Red or White Winemaking or one of the winemaking books that we offer for a complete explanation on how to properly manage sulfites. In addition, it's important to keep in mind that free SO2 levels fall faster in wood cooperage than in glass or stainless, so if you are using a barrel you will most likely need to manage sulfite levels more closely. The most common form of Metabisulfite is as a powder which is fixed with potassium or sodium. 1/4 tsp of Potassium Metabisulfite adds 50ppm to 5 gallons of must. Old Metabisulfite loses potency with time and should be replaced every year to assure that you are getting correct levels. You can use old Metabisulfite to make solutions for sanitizing equipment.

Lallemand Fermaid O | Yeast Nutrient | Organic Nitrogen | No Added DAP
Fermaid O is a newer formulation of the same Fermaid K that winemakers everywhere have learned to trust their ferments to. The main difference in composition between the two, is that the Fermaid O has replaced the inorganic DAP with an organic source. In terms of how this benefits the winemaker, there are several points! Features: Organic Nitrogen is easier for your yeast to digest, resulting in a smoother, more consistent fermentation. Fewer fermentation spikes means better yeast health, and the ability to ferment to its full capacity. Compared to DAP, Fermaid O will result in lower heat output from the yeast, and lower levels of negative sulfur compounds. This is a nutrient which will boost the quality of wine, regardless of process. Lower heat production, less negative flavor compounds, better overall fermentation kinetics and flavors! To Use: Use at a rate of 1.5g / gal of must/juice. Like Fermaid O? Then you will love CellarScience® FermFed DAP Free Yeast Nutrient!

Lallzyme EX | Fermentation Enzyme for Early Drinking Red Wines
Specially formulated enzyme preparation for improved color intensity and stability, greater mouthfeel, and enhanced fruity, floral, spicy flavors in wine. Used primarily in red wines for the aforementioned reasons, it can also be used in white wines for increased extraction (however we recommend Lallzyme C-Max for whites because it helps the solids settle out as well). Based on the activity of a blend of cellulases, hemicellulases, and pectinases, this preparation aids in the extraction, then stabilization of water soluble phenols found in cells of grape skins. A dry, granular product requiring no special storage conditions prior to use. We have used this enzyme on our wine here at MoreWine and found the difference to be nothing short of amazing. Currently only available at MoreWine in this size! To use dissolve Lallzyme EX into a sufficient amount of water (usual ration is 1:100) and add to must with your other additions prior to the onset of fermentation. Dosage is 0.1g Lallzyme per gallon of must. Store dry enzyme at room temperature, around 25 C° (77 F°). Once rehydrated use within a few hours.

Tannin FT Rouge
This product replaces our TAN120 - Tannin VR Supra Enological tannins offer the winemaker the possibility to add refined, highly-bindable tannin to your wine at any stage during the process. Benefits can include increased structure and mouthfeel, color stabilization, stability, anti-oxidative qualities, and overall complexity. Tannins can reduce vegetal/herbaceous characteristics and perceived astringency. We offer four types of oenolgical tannins, two for use during fermentation, and two for use during the aging phase. How Fermentation Tannins Work Designed specifically for North American red wine fermentations, Scott'Tan FT Rouge is composed of exotic wood and chestnut tannins. These highly reactive tannins bind with anthocyanins (color compounds) in the first 3-4 days of fermentation. If sufficient natural tannins are not present in must, anthocyanins may precipitate, resulting in a loss of color. Using an enzyme like Lallzyme EX in conjunction with FT Rouge can enhance this binding of color. The continual bonding going on throughout the ferment will also improve the mid palate structure and help either significantly reduce or eliminate vegetal/herbaceous characters. Tannin additions at this early stage prove to be most efficient and are better integrated into the wine. Important!: If being used in conjunction with one another, tannins should be added 6-8 hours after the addition of the enzymes or you run the risk of having the tannins reacting with and removing the enzymes before they have had a chance to do their job!. To Use Sprinkle directly onto must and either mix well with your punch down tool or pump over to ensure thorough mixing. If adding to the wine post-fermentation we recommend allowing 3-6 weeks for full integration before racking, fining, filtering or bottling. Recommended dosage rate: 0.8-1.9 g/gal. Use at an initial rate of 1.3 gram per gallon during punch down/pump over. If you want additional tannin add at a rate of .25 g/gal. A rough approximate of weight is 1 tsp = 2.4 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates. Unopened the shelf life is 5 years at 18ºC(65ºF).

CellarScience® FermStart | Yeast Rehydration Nutrient
Start your fermentation right with FermStart by CellarScience®. FermStart is a concentrated, micronutrient blend that helps yeast during the critical phase in which they transition from dried and dormant back into healthy and active. FermStart is added to your rehydration water so that your yeast absorbs the nutrients as they absorb the water. Rehydrating with FermStart prior to pitching your yeast also has the added benefit of allowing the yeast access to the nutrients before wild yeast in the must can uptake them. Rehydrating with FermStart = Healthy Yeast Rehydrating your yeast is always recommended but is considered especially important at any Brix level above 14. Rehydrating with FermStart is the gold level of hydration and helps protect your yeast against initial osmotic pressures, competition from wild yeast, and alcohol toxicity. Proper hydration and healthy yeast have also shown to have a positive impact on flavor. How Much? FermStart is a super concentrated formula, which is very convenient when you are rehydrating large amounts of yeast. Use 1 gram of FermStart for every 4 grams of yeast. We offer some suggested ranges for the amount of water to use below. Examples: 8g yeast – Add 2g FermStart to 30-50ml of water 80g yeast – Add 20g FermStart to 300-400ml of water 500g yeast – Add 125g FermStart to 1500-2000ml of water The Science of How it Works FermStart is rich in readily assimilable amino acids, sterols, vitamins, and natural glutathione. Readily assimilable means that the size of the molecules present in FermStart are all extremely small and easily absorbed by the yeast cell. This is obtained by centrifuge and allows FermStart to be extremely concentrated and not contain filler. The availability of readily assimilable amino acids allows the yeast cell to skip the step in which amino acids would be synthesized within the cell. This saved energy is instead directed into multiplication. Faster yeast cell multiplication means a faster fermentation start, allowing your yeast to out-compete wild yeast. Wild yeast have unknown flavors and fermentation behavior, so it is important to give your selected yeast the best chance to dominate the fermentation. Sterols help the cell membrane regain and maintain elasticity helping to ensure a perfect start and continued performance throughout the fermentation. The strong cell membrane helps ensure that the yeast can survive and complete alcoholic fermentation under tough conditions. Glutathione is a very special natural antioxidant and detoxifier made up of three amino acids – cysteine, glutamate, and glycine. It is extremely important for maintaining intracellular health by preventing damage to cellular components during the very oxidative process of rehydration. FermStart does not contain nitrogen which is detrimental to the yeast cell during hydration. Nitrogen can be added through the addition of FermFed or FermFed DAP free nutrients at the first signs of fermentation. Another addition is then added at 1/3 sugar depletion to complete a total fermentation nutrient schedule. For a full yeast nutritional plan, use FermStart when rehydrating your yeast, FermFed DAP Free at the onset of fermentation, and FermFed after 1/3 sugar depletion.

Lallzyme C-Max |
Enhances clarification and static settling of white and rosé musts under extreme conditions Active and fast depectinisation at low temperature, low pH, or high total pectin content Produces rapid, compact lees and improves juice quality consistently Requires lower dosage for effective results compared to standard enzymes Cinnamyl-esterase-free pectinase blend minimizes ethylphenol precursor release Lallzyme C-MAX™ is a micro-granulated pectolytic enzyme derived from Aspergillus niger, formulated for use in white and rosé wine production where settling conditions may be difficult. With high activities of pectin lyase, pectin methyl esterase, and polygalacturonase, it provides fast, efficient breakdown of pectin, even at low temperatures (as low as 8 °C / 46 °F) or low pH. Its action reduces must viscosity, speeds up clarification, and generates compact, easy-to-rack lees. Because it contains no cinnamyl esterase, Lallzyme C-MAX™ also limits the formation of ethylphenol precursors, contributing to cleaner, more varietally expressive wines. Protocol for Use: Add after pressing or directly into the settling tank. Dilute the enzyme in 10 times its weight in water or juice before use. Mix thoroughly for uniform distribution. Do not add bentonite during enzyme treatment. Clarification typically completes within 24 hours depending on temperature and juice conditions. Usage Rates: Standard conditions (>12 °C / 54 °F): 0.5–1.0 g/hL = 0.005–0.01 g/L = 0.019–0.038 g/gal Cold or high-pectin conditions (8–12 °C / 46–54 °F): 1.0–2.0 g/hL = 0.01–0.02 g/L = 0.038–0.076 g/gal Store in original sealed packaging at 5–15 °C (41–59 °F) in a dry place.

Benefits can include increased structure and mouthfeel, color stabilization, stability, anti-oxidative qualities, and overall complexity. Tannins can reduce vegetal/herbaceous characteristics and perceived astringency. We offer four types of oenolgical tannins, two for use during fermentation, and two for use during the aging phase. Aging tannins Tannin Complex is a tannin that is added post fermentation to improve the overall structure and to help protect the wine from oxidation during aging. It is composed of proanthocyanidins and ellagic tannins that integrate easily into young wines. Tannin Complex was specially developed to add structure and a soft mid palate to premium red wines without harshness or a forward oak finish. It can also enhance the varietal fruit character while adding complexity to the finish. Helps stabilize wines by improving the polyphenolic composition. It is especially useful when aging wines in older tannin-leached barrels and with full, fruity, lower tannin varietals like Syrah and Zinfandel. To Use: While racking or stirring, add Tannin Complex to the wine incrementally. Mix well to ensure homogeneity. Final addition should be made 3-6 weeks before bottling to allow for complete polymerization and settling. Use at the rate of 0.20-1.14 g/gal (5-30 g/hL) prior to aging. A rough approximate of weight is 1 tsp = 3.1 grams. We highly recommend using a scale to weigh the product for an accurate dose.

Potassium Carbonate
Potassium Carbonate is used to lower acidity levels in wine. 3.8 grams per gallon will reduce acidity by about .1%. Potassium Carbonate requires that the fermenter be stored cold for several weeks after application (please see our guides to Cold Stabilization in the documents tab above). During the period of cold stabilization the tartaric acid drops out as potassium bitartrate. Doing a trial run with a small amount is strongly suggested to determine exactly what the drop in acidity will be. Calcium carbonate can be used in a similar manner and does not require cold stabilization. However it adversely affects flavor, takes month to precipitate out of solution, and preferentially reduces tartaric acid first before affecting malic or citric acid. A rough approximate of weight is 1 tsp = 8.3 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Lallemand Reduless | Inactivated Yeast with Copper | Fixes H2S Issues
Reduless is a new product from Lallemand that was designed to correct negative VSCs (Voltatile Sulfur Compounds) such as H2S (hydrogen sulfide, A.K.A. "rotten egg") and DMS (dimethyl sulfide, A.K.A. "cooked corn") defects in wine. Made from inactivated yeast that have been infused with copper using a proprietary process, Reduless is a much gentler H2S remedy on the wine than the traditional copper sulfate (CuSO4) treatment alone. If you have an H2S problem, then we recommend treating it with Reduless first. However, if the sulfur problem still remains after the Reduless treatment, then a bench trial with copper sulfate (CuSO4) is recommended. Note: The sooner you catch a sulfur problem the easier it is to deal with! To Use: Dissolve Reduless in 10 times it's weight in water and add immediately to the wine. Stir the wine gently to ensure a thorough homogenization. Rack or filter after 72 hours. Recommended Dosage: 0.4-0.6 g/gal. The maximum amount of copper that can be released into the wine using Reduless at the recommended dosage is 0.02 ppm.

Bentonite | Volclay KWK Krystal Klear
Volclay KWK Krystal Klear Bentonite is a clay-like mineral with a negative charge that, similar to Sparkolloid, removes positively charged particles. It is most effective when the wine is at a warmer temperature, so we recommend using it for fining in late spring or early summer. It also works better at lower pH levels because proteins have a stronger positive charge in more acidic conditions. Generic Low-Level Fining for 5 Gallons: Blend 1/2 tsp (about 3g) of bentonite with 1/2 cup of hot water (140 to 200°F) in a blender for 1-2 minutes. Let the mixture sit for 60 minutes, then stir it well before adding it to the wine. Allow the wine to stand for 10-14 days before racking off. This method achieves a fining rate of 0.16g/L. Generic Mid-Level Fining: Follow the same steps as above but use 9 grams of bentonite and 3/4 cup of hot water. This method achieves a fining rate of 0.5g/L. More Scientific Approach: You can create a 5% bentonite stock solution and run bench trials to determine the lowest effective concentration for clearing the wine. Since fining is non-selective, it removes both undesirable particles like yeast and some desirable phenolic compounds. Therefore, it's best to use the lowest effective concentration. To make a 5% solution, dissolve 50 grams of bentonite in 850ml of hot water, mix thoroughly, and top up with water to a final volume of 1L. Set up trials with clear jars of equal volume, adding varying amounts of the solution to achieve addition rates between 0.3g/L and 2.0g/L. You’ll need to do some calculations to determine the right amount for your needs. Let the trials clear overnight. For more detailed technical information, consult BK653 - Monitoring the Winemaking Process from Grapes to Wine - Techniques & Concepts. Fining with Wine Kits: When using a wine kit made from concentrate, bentonite is typically added on the first day for a few reasons. It serves as a nucleation site for CO2 removal. The CO2 movement helps distribute the bentonite throughout the wine, allowing you to use less and achieve effective fining in a shorter time.

CellarScience® FermFed DAP Free | Yeast Nutrient
Feed your fermentation with FermFed DAP Free by CellarScience®. The 100% natural formulation of FermFed DAP Free is derived from the autolysis of very specific yeast strains naturally high in free amino acids, sterols, mannoproteins, zinc, magnesium, and niacin, along with vitamins B1, B2, B5, B6, and B12 for a complete yeast health regimen. As the name suggests, this unique formulation does not contain the traditional inorganic diammonium phosphate, but does provide organically derived nitrogen. How Much Do I Add and When? The recommendation that covers most fermentations is to add 1.5 gram per gallon of FermFed DAP Free at the onset of fermentation and then add 1 gram per gallon of FermFed after 1/3 sugar depletion. Mix the nutrients in a small slurry of water and add to the fermentation. Read more below if you are interested in measuring YAN (Yeast Available Nitrogen) and adjusting your nutrient schedule accordingly. The Science of How it Works The different components of FermFed DAP Free work in different ways to feed and protect your yeast. The complex and organic nitrogen in FermFed DAP Free helps eliminate excessive yeast growth in the initial phases, reducing fermentation heat spikes at the start of fermentation. Included sterols make the yeast membrane more resistant to alcohol and to high temperatures. The collection of B-vitamins along with zinc and magnesium are essential for enzymatic activity, alcohol tolerance, and yeast health. Mannoproteins help avoid the aromatic stripping during the fermentation by binding esters and terpenes and not allowing them to be driven off by CO2. The included yeast hull components act as receptors to bind up fatty acids that can accumulate and cause stuck fermentations. Advanced - Adjusting Your Nutrient Schedule Based on YAN (Yeast Available Nitrogen) In addition to the nutrients provided by FermFed or FermFed DAP Free, yeast need a certain level of nitrogen to perform adequately. If deprived of nitrogen, yeast are more likely to produce off flavors, most notably hydrogen sulfide. When added at the rate of 1 gram per gallon, FermFed provides 38ppm of YAN while FermFed DAP Free adds 20ppm when added at the rate of 1.5 gram per gallon. How much YAN do you need? Acceptable levels range from 175 to 300ppm. YAN levels in grapes vary, with grapes from warmer climates often having less. The best practice is to measure your grapes using a commercial wine lab or the Vinmetrica YAN Test Kit along with a Vinmetrica Meter. If you know your YAN the following is a good general guide: 175ppm or above = FermFed DAP Free @ onset + FermFed DAP Free @ 1/3 completion (adds 40ppm YAN) 150ppm or above = FermFed DAP Free @ onset + FermFed @ 1/3 completion (adds 58ppm YAN) 125ppm or above = FermFed @ onset + FermFed @ 1/3 completion (adds 72ppm YAN) Below 125ppm = FermFed @ onset + FermFed @ 1/3 completion + extra DAP For a full yeast nutritional plan, use FermStart when rehydrating your yeast, use FermFed DAP Free at the onset of fermentation, and use FermFed after 1/3 sugar depletion.

Tannin Riche Extra
This product replaces our TAN140 - Tannin Plus Enological tannins offer the winemaker the possibility to add refined, highly-bindable tannin to your wine at any stage during the process. Benefits can include increased structure and mouthfeel, color stabilization, stability, anti-oxidative qualities, and overall complexity. Tannins can reduce vegetal/herbaceous characteristics and perceived astringency. We offer four types of oenolgical tannins, two for use during fermentation, and two for use during the aging phase. Aging Tannins Tannin Riche Extra is a preparation of 100% American oak tannin that has been lightly toasted to impart a soft, aromatic character while enhancing the structure and organoleptic complexity of a wine. Tannin Riche Extra is a great tool for imparting hints of coconut, a heightened vanillin oak character and a smooth finish to your wines. Although designed for fine-tuning a wine, Tannin Riche Extra still maintains the regular properties associated with the use of tannins such as helping with clarification, stability, oxidation, and aging. Works well in conjunction with low doses of other tannins (i.e: Tannin Complex & FT Blanc Soft). To Use: Dissolve the tannin in 10 times its weight in warm water (95F/35C). Add to the wine during a punch-down or pump-over for good mixing. Addition of Tannin Plus should be made a minimum of three weeks before bottling. Recommended dosage: 0.2-0.4 g/gal A rough approximate of weight is 3/4 tsp = 1 gram. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

CellarScience® FermFed | Yeast Nutrient
Help your yeast reach the end of fermentation safely while producing amazing flavors with FermFed by CellarScience®. Yeast that are given FermFed have a higher likelihood of fermenting without issue while producing wines with more intense flavors and aromas. FermFed is a complex nutrient blend of diammonium phosphate, thiamin, amino acids, sterols, pantothenic acid, mannoproteins, protective microelements derived from yeast hulls, and vitamins B2, B5, B6, & B12. FermFed also contains the organic and inorganic nitrogen (DAP) that yeast need. How Much Do I Add and When? The recommendation that covers most fermentations is to add 1 gram per gallon of FermFed DAP Free at the onset of fermentation and then add 1 gram per gallon of FermFed after 1/3 sugar depletion. Mix the nutrients in a small slurry of water and add to the fermentation. Read more below if you are interested in measuring YAN (Yeast Available Nitrogen) and adjusting your nutrient schedule accordingly. The Science of How it Works The different components of FermFed work in different ways to feed and protect your yeast. Grape must/juice is often deficient in assimilable nitrogen. When yeast do not have enough nitrogen, they are more likely to produce hydrogen sulfide (rotten eggs). FermFed helps to eliminate this problem by providing enough nitrogen for most situations. Yeast get weaker as they divide and multiply. They run the risk of not being able to properly finish fermentation as the alcohol content rises. Feeding them sterols help cells maintain membrane fluidity so that the yeast can properly function as alcohol and other harmful compounds in the fermentation conspire against them. Mannoprotein molecules bind esters and terpenes and work as an anchor to keep them in solution so they are not driven off by CO2 during fermentation. Pantothenic acid is added to help reduce the production of hydrogen sulfide. Thiamine is important for yeast metabolism. Vitamins B2, B5, B6, & B12 are important for general yeast health. Advanced - Adjusting Your Nutrient Schedule Based on YAN (Yeast Available Nitrogen) In addition to the nutrients provided by FermFed or FermFed DAP Free, yeast need a certain level of nitrogen to perform adequately. If deprived of nitrogen, yeast are more likely to produce off flavors, most notably hydrogen sulfide. When added at the rate of 1 gram per gallon, FermFed provides 38ppm of YAN while FermFed DAP Free adds 20ppm. How much YAN do you need? Acceptable levels range from 175 to 300ppm.

An acceptable level for YAN is between 200 to 350ppm FermFed provides 38ppm of Yan when added at the rate of 1 gram per gallon. The reason we don’t automatically use FermFed for a Stage 2 is that we don’t want to introduce excessive amounts of DAP into the wine if your yeast don’t need it. For a full yeast nutritional plan, use FermStart when rehydrating your yeast, use FermFed DAP Free at the onset of fermentation, and use FermFed after 1/3 sugar depletion.

Delvozyme® (Lysozyme)
Wine Making Use Delvozyme (Lysozyme, Lysovin) for controlling lactic acid bacteria growth in your wine. Isolated from egg whites, this enzyme will degrade the cell wall of gram positive bacteria, but will not affect yeast or gram negative bacteria such as Acetobacter. Delvozyme can be used for both Red and White Wine Malo Fermentation. Dosage: To Delay Malolactic Fermentation: Red Wine - add to grapes at 100 - 200 ppm, or 0.38 - 0.76 grams per gallon. White Wine - Add to must at 200 - 300 ppm, or 0.76 - 1.14 grams per gallon. To Block Malolactic Fermentation: White Wine - Add to must or wine at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon. Stabilizing wine after MLF is complete: Add to barrel during storage at 250 - 500 ppm, or 0.95 - 1.90 grams per gallon. When blending partial and complete MLF wines: Add immeditatley after blending at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon, to reduce the risk of further malolactic fermentation (MLF). Within several days any lactic should expire. For sluggish or stuck yeast fermentation: Red Wine - Add at 150 - 400 ppm, or 0.57 - 1.52 grams per gallon. White Wine - add at 300 - 500 ppm, or 1.14 - 1.90 grams per gallon. Directions for use: You can make a 10% solution of Delvozyme in water (100 grams per liter of water). However we find the easiest method is to add the desired dry weight of Lysovin in 5x its weight of warm(tepid) water. Mix for one minute, allow this mixture to stand for 45 minutes and add to must, juice or wine while mixing well. Allow 24 - 48 hours for reaction to complete. **Note: 3tsp Delvozyme = 5g Beer Making Delvozyme can be used in beer making as well. Use either in the starter (recommended if you make starters) or when pitching (adding) the yeast to the wort, do not use over 140 F. Recommended dosages is 1 tsp per 5 gallons of wort. According to studies it has no effect on flavor or clarity. Storage: Should be stored at room temperatures in a dry environment, can be stored up to 5 years.

Lallzyme Cuvee Blanc | Fermentation Enzyme for White Wines
Lallzyme Cuvee Blanc – Enzyme for Aroma Release and Finesse in White and Sparkling Wines Enhances aroma expression by unlocking bound terpene and thiol precursors Improves clarification and filterability through efficient pectin breakdown Increases finesse and texture by gently releasing polysaccharides Ideal for varietal whites and sparkling base wines where delicacy is key Balanced glycosidase activity preserves freshness without compromising stability Lallzyme Cuvee Blanc is a highly specific enzyme developed by Lallemand for the production of elegant, aromatic white and sparkling wines. It offers a delicate balance of pectinase and glycosidase activity that breaks down grape cell walls to improve clarification while simultaneously releasing aroma precursors trapped in glycosidic form. This selective activity enhances varietal expression—especially in terpene- and thiol-rich varieties—without producing off-flavors or excessive bitterness. The result is a wine with lifted aromatics, better mouthfeel, and improved stability, ideal for styles requiring precision and finesse. Protocol Dilute Lallzyme Cuvee Blanc in 10 times its weight of chlorine-free water. Add to juice or wine at the preferred stage—either pre-fermentation for aroma release and settling, or post-fermentation for finishing and clarification. Ensure even distribution by mixing thoroughly. Optimal temperature range is 12–20°C. Avoid use below 10°C or in combination with bentonite or SO₂ during addition. Usage Rates Recommended dosage: 2–4 grams per hectoliter = 0.02–0.04 grams per liter = 0.076–0.151 grams per gallon Use 2 g/hL for lighter aromatics or wines already showing good varietal character. Increase to 4 g/hL in more neutral juices or when maximizing aromatic potential is desired. Allow adequate contact time—typically 24 to 48 hours—depending on the winemaking stage and style.

We will automatically ship this to you when we receive more inventory. 3.4g per gallon adjusts acidity by +.1%. It will lower pH less than will tartaric acid. Malic acid is the acid found in apples and is therefore the best choice for adjusting ciders. Malic is less sour than tartaric acid and can also be used to make acid adjustments in Rieslings, Gewurztraminer, and Muscat varieties, though many winemakers still prefer to use tartaric acid in these situations. You would not want to add Malic acid to any wine that will undergo a malolactic fermentation. As a note: only half of the artificially added malic acid will convert to lactic acid during a malolactic fermentation. A rough approximate of weight is 1 tsp = 2.7 grams.

Yeast Hulls | For Stuck or Sluggish Ferments
Yeast Hulls are ususally the first action when you have a stuck or sluggish alcoholic or malolactic fermentation. Yeast Hulls are essentially dead yeast cells that absorb auto toxic yeast by-products that could be inhibiting your active yeast or ML culture from doing their job - finishing your fermentation! Yeast Hulls are then typically followed by Pro-Desert in the case of a stuck alcoholic fermentation or Acti Ml in the case of a stuck ML ferment. As a side note, Yeast Hulls are included in the Fermaid K mix of nutrients to help prevent problem ferments from the onset. The reason you would not use Fermaid K for most stuck ferments is that Fermaid K contains DAP. If DAP (Diammonium Phosphate) is added to the ferment past the point of metabolization by the yeast it could potentially leave an unwanted, residual flavor. Use at the rate of .5 to .9 grams per gallon. If stored in a cool, dry place, will last up to 3 years. A rough approximate of weight is 1 tsp = 2 grams. We highly recommend using a scale to weigh the product for an accurate dose. We do not recommend relying on these rough conversions for accurate dosage rates.

Copper Sulfate (1%) | 1 oz
Some homewinemakers will treat wine affected with Hydrogen Sulfide (rotten egg smell) by stirring with a copper rod or racking through a copper "scrubby". Copper converts the the hydrogen sulfide into copper sulfide, which is not soluble in wine. After a few days the wine is racked off the copper sulfide which by that time has precipitated down to the bottom of your vessel. However, putting wine in direct contact with a non-measured amount of copper can result in residual copper being left in your wine, especially in low pH environments. A more professional approach to the reduciton of Hydrogen Sulfide is to use a measured amount of copper sulfate in a 1% solution. Normally a trial is set up to determine the least amount needed to eliminate the problem (see FIN84 bench trial kit). Because the amounts used are very small, it will be necessary to use a pipette. Add the correct amount of copper sulphate in small .1 ppm doses. Wait several days for the copper sulfide to settle out and then rack off the lees. Do not add copper sulphate during an active fermentation as it may actually cause more hydrogen sulfide to form. If you detect hydrongen sulfide or "rotten egg" smell during fermentation, it is a sign of poor yeast nutrition. Add the recommended amount of Fermaid K (AD345) for the amount of yeast you used to correct this issue - it should keep you from having to use the copper later!

Ascorbic Acid
Due to high demand, this item is currently out of stock. Be the first to receive your items by placing a pre-order today. We will automatically ship this to you when we receive more inventory. Ascorbic acid is a quick-acting and powerful antioxidant that is used in white winemaking to protect against light and short aerations, such as racking and bottling. It works by rapidly converting dissolved oxygen into hydrogen peroxide before it has a chance to react with oxidative enzymes and cause browning. However, this hydrogen peroxide itself needs to be removed from the wine in order to avoid the very phenomenon that was trying to be avoided in the first place, namely oxidizing the wine. The answer lies in always making sure that the free SO2 levels are correct, both before the ascorbic addition is to be made and after. (Note that "Titrettes" are not accurate enough for this, and that a more precise means of determing free SO2 is needed, such as an Aeration-Oxidation set-up). Addition rate is around 50 mg/l (ppm) as long as the free SO2 is maintained at 30 mg/l (ppm). A rough approximate of weight is 1 tsp = 3.2 grams.

Scottzyme KS | For Difficult Wines When Pec5L is Not Enough
cottzyme KS – High-Power Enzyme for Complex Pectin Breakdown in Red, White, and Problem Wines Breaks down complex, highly esterified pectins that standard pectinases cannot Enhances clarification, settling, and filterability in challenging juices and wines Boosts juice and wine yield by improving extraction from thick-skinned or high-pectin fruit Ideal for problem fermentations or hazy wines that resist fining and filtration Performs well at low temperatures and in a broad pH range Scottzyme KS is a specialized pectolytic enzyme designed to break down complex pectin structures found in high-pectin varietals and difficult ferments. While standard enzymes like PEC5L target simple soluble pectins, KS is formulated with enhanced side-chain cleaving activity that attacks esterified pectins and heavily branched structures. This makes it particularly effective on cultivars like Pinot Gris, Riesling, Gewürztraminer, Muscat, and in juice or wine where haze persists despite prior enzymatic treatment. KS improves clarification, tightens lees, increases press and wine yields, and boosts filtration efficiency—especially in wines that defy typical settling protocols. Comparison to Scottzyme PEC5L: Scottzyme PEC5L is a fast-acting general-purpose pectinase for typical clarification tasks, such as settling and flotation of white and rosé juices. It’s ideal for clean juice production from standard grapes and most fruit wines. In contrast, KS is the go-to choice when PEC5L isn’t enough—it’s stronger on stubborn, esterified pectins and delivers better results with problematic varieties or ferments that remain hazy even after PEC5L. While PEC5L is excellent for fast juice prep, KS excels in the most difficult cases, including post-fermentation haze and challenging press fractions. Protocol Dilute Scottzyme KS in 10 times its volume of chlorine-free water or juice. Add to must, juice, or wine and mix well. Suitable for use before or after fermentation. Do not add simultaneously with bentonite or high SO₂. Works effectively at 10–20°C. Usage Rates Recommended dosage: 1.5–4.0 mL per 1000 lb of fruit or 0.075–0.2 mL per gallon = approximately 0.02–0.05 mL per liter Use lower rates for moderate haze and extended contact time. Use higher rates in cold settling, high-pectin juices, or persistent post-fermentation hazes. Allow 4–24 hours of contact time depending on application.

Nutrient Vit End | Fermentation Nutrient for End of Fermentation
Vit End – Lallemand Yeast Nutrient for Securing Fermentation Completion Supports yeast vitality during the final stages of alcoholic fermentation Provides essential vitamins, minerals, and survival factors to avoid sluggish finishes Reduces the risk of stuck fermentation by reactivating stressed or nutrient-starved yeast Enhances sugar-to-ethanol conversion efficiency for cleaner fermentation ends More targeted than general nutrients due to its late-fermentation formulation Vit End is a specialized nutrient developed by Lallemand for use at the end of alcoholic fermentation, when yeast cells are most vulnerable to nutrient depletion, ethanol toxicity, and osmotic stress. Unlike standard yeast nutrients formulated for the growth phase, Vit End is designed to support cell survival, membrane integrity, and residual sugar metabolism. It contains inactivated yeast rich in survival factors, specific vitamins, minerals, and sterols that help re-energize exhausted yeast populations, allowing them to finish fermentation smoothly. Wines showing signs of slowing kinetics, high residual sugar, or difficult fermentation conditions benefit from the targeted support Vit End provides. Protocol Suspend Vit End in ten times its weight of clean must or wine at 20–25°C. Stir thoroughly to dissolve. Add when fermentation is slowing (often near 0–5°Brix) or when signs of yeast stress appear. Mix well to ensure even distribution. Do not add simultaneously with bentonite or sulfites. Usage Rates Recommended dosage: 20–40 grams per hectoliter = 0.2–0.4 grams per liter = 0.76–1.5 grams per gallon Use 20 g/hL in moderate stress conditions. Increase to 40 g/hL in fermentations that are near-stuck, have high residual sugar, or show signs of yeast stress. Vit End can also be used proactively in fermentations known to be high-risk due to low YAN, high sugar, or challenging varietals.

Lallemand RESKUE™ | For Stuck or Sluggish Ferments | More Effective than Yeast Hulls
Reskue – Yeast Derivative Nutrient for Detoxifying and Restarting Stuck Fermentations Detoxifies fermentations by adsorbing toxic fatty acids that inhibit yeast and bacteria Restores sugar uptake by clearing compounds that interfere with yeast membrane function Reinvigorates both sluggish or stuck alcoholic and malolactic fermentations Contains no measurable YAN, so it won't impact nutrient balance or promote excess yeast growth More effective than standard yeast hulls due to its targeted high-capacity bioadsorptive properties Reskue is a specific inactivated yeast derivative developed by Lallemand to help winemakers recover from sluggish or stuck fermentations. Unlike generic yeast hulls, which offer general detoxification support, Reskue is produced using a proprietary process that dramatically enhances its surface area and binding capacity for fermentation-inhibiting compounds—especially short- and medium-chain fatty acids. These compounds are produced by stressed yeast and can block sugar transport, stalling fermentation. Reskue removes them more efficiently than standard hulls, helping yeast and bacteria resume healthy metabolic activity. This makes Reskue particularly valuable not only in stuck alcoholic fermentations but also in challenging malolactic fermentations where similar toxins can block bacterial performance. Protocol Suspend Reskue in 10 times its weight of clean water at 30–37°C (86–98°F). Stir thoroughly and let sit for 20 minutes before adding to the fermentation. Mix evenly into the tank. In stuck alcoholic fermentations, allow Reskue to settle for 48 hours, then rack off before initiating the restart protocol. Usage Rates Recommended dosage: 30–40 grams per hectoliter = 0.3–0.4 grams per liter = 1.14–1.5 grams per gallon Use 30 g/hL for moderate ferment stress and 40 g/hL when conditions are severe or when toxic byproducts are strongly suspected. Reskue is not a nutrient supplement—it provides virtually no YAN—and should be used as a detoxification tool to restore a viable fermentation environment.nd dry.
