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.

Campden Tablets - Sodium Metabisulphite (25 Tablets)
13 reviews

An essential ingredient in winemaking. Sodium Metabisulfite, (often referred to as SO2, sulfites meta, or meta-bi) has several uses in winemaking. It is used at the crush, to help control the spoilage bacteria and indigenous yeast that may already be present on the fruit or the equipment. The amount used is enough to stop most of the unwanted organisms but not enough to hinder a cultured yeast, which has a higher tolerance to sulfites. This effectively “wipes the slate clean” for the cultured yeast to step in and rapidly colonize the must. Sulfites also help to inhibit the enzymatic browning of musts and finished wines. During storage and in the bottle, sulfites at the proper levels will protect a wine by continuing to inhibit spoilage organisms, as well as by scavenging oxygen. Campden tablets are Sodium Metabisulfite in an easier to measure format. Adds 75 ppm of sulfites at the rate of one tablet per gallon. These must be fully ground-up prior to use. Potassium Meta-bi in powder form, AD495 or AD500, is much easier to use if you have a scale and does not add sodium to your wine. It is possible the sodium could contribute a very small salty flavor. Especially when making white wine it is preferable to add potassium over sodium since added potassium can later help with cold stabilization. For more information 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.

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.

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.

R-2 Dry Wine Yeast

R2 was isolated in the Sauternes region of Bordeaux by Brian Croser of South Australia. In addition to enhancing esters and mouthfeel, it has excellent cold temperature properties and will ferment as low as 50 degrees F, making it ideal for Icewine production. However, if it does not get proper nutrients it can tend to produce VA and H2S. For this reason, hydration with GO-FERM and the addition of Fermaid K is definitely recommended to optimize its' potential. R2 helps produce intense, direct fruit style whites by liberation of fruity and floral fermentative aromas. R2 also helps to enhance the varietal chacter by an enzymatic release of bound aroma precursors. It is recommended for aromatic white varieties such as Sauvignon Blanc, Riesling, Gewurztraminer, Chenin Blanc, Vidal, and Seyval. It is classified as a Saccharomyces cerevisiae bayanus. Best results from 50 to 86 degrees F, with an alcohol tolerance to 16%. Download the PDF Download the PDF

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.

VL3 Dry Wine Yeast

VL3 is a Bordeaux isolate that was selected following in-depth research identifying the molecules responsible for Sauvignon Blanc aroma. VL3 was found to enhance Sauvignon Blanc varietal characters and aromas (Mercaptopentanone, Mercaptohexanol, etc.) Subsequent experimentation has found this to be true of other white varietals such as Riesling, Pinot Gris, and Pinot Blanc as well. VL3 is well suited to aging on the lees and produces very low levels of VA and SO2. A premier yeast for Sauvignon Blanc fermentation worldwide. It is important to note that many of the sought after compounds that are enhanced by VL3 are actually sulfur based, so the use of oxygen and or Cu (copper) will effectively diminish or even remove them from the final wine if used in excess. Therefore, the use of nutrients is strongly recommended to avoid any H2S problems that would require oxygen or Cu to counteract. Best results from 60 to 68 degrees F, with an alcohol tolerance to 14%. Download the PDF Download the PDF

Calcium Carbonate
7 reviews

Calcium carbonate is used to reduce the acidity of wine. It does not require cold-stabilization to force complete precipitation, as does potassium carbonate. However, calcium carbonate is more likely to affect the flavor than potassium carbonate, and may take a few months to fully precipitate. One-quarter ounce (about 4 teaspoons) of calcium carbonate reduces acidity in one gallon by about 0.25%. Foaming may occur because of the production of CO2. Do not use more than one ounce per gallon. Wait 24 hours and rack wine. Calcium carbonate is also used in beer to increase the temporary hardness of water. Traditionally used in English stouts, pale ales and bitters. Usage: Usage varies with acid level Common name: Chalk

Scottzyme Pec5L | Pectinase | Add to Must or Juice | Increases Yield

Scottzyme PEC5L – Pectinase Enzyme for Enhanced Settling and Juice Yield Rapidly breaks down soluble pectins for faster settling and improved clarity Increases free-run and press yield by reducing viscosity and cell wall resistance Improves flotation efficiency and tightens lees compaction Effective across a wide pH range and performs well at low temperatures Ideal for white, rosé, and fruit wines requiring fast clarification and clean separation Scottzyme PEC5L is a highly active liquid pectinase enzyme formulated to reduce pectin-related haze and increase processing efficiency in juice production. By breaking down soluble pectins, PEC5L dramatically improves juice release during pressing, reduces must viscosity, and accelerates settling or flotation. The result is clearer juice, more compact lees, and higher overall yield. Its formulation is optimized for cool-temperature performance and a broad pH range, making it a versatile tool in grape and non-grape juice clarification. Unlike general pectinases, PEC5L is designed to act quickly and cleanly, without over-extraction of phenolics or bitterness. Protocol Dilute Scottzyme PEC5L in 10 times its volume of chlorine-free water or juice. Add to must or juice immediately after crushing or during transfer to settling tank. Mix well to ensure even distribution. For flotation, add just before or during the flotation process. Avoid adding at the same time as SO₂ or bentonite. Usage Rates Recommended dosage: 1.5–4.0 mL per 1000 lb of fruit or 0.075–0.2 mL per gallon of juice = approximately 0.02–0.05 mL per liter Use lower rates for clean, low-pectin fruit or warmer temperatures. Use higher rates for pectin-rich grapes, low temperatures, or difficult-to-settle musts. Allow contact time of 2 to 12 hours depending on conditions and desired level of clarification.

CellarScience® BIG RED Dry Wine Yeast | Premium Wine Yeast

Recomended for aged red wines High color extraction Significant polysaccaride and glycerol production for huge mouthfeel High alcohol tolerence High nutrient need Top choice for Bordeaux varietals Cabernet, Cab Franc, Petite Verdot and Merlot Also excelletnt for Sangiovese, Nebbiolo and some Pinot The name kind of says it all. BIG RED is ideal for producing big, complex red wines with lasting fruit. Depending on the grape varietal used it can emphasize complex berry fruit and spice flavors. This strain is very efficient at breaking down and extracting tannins and anthocyanins from grape skin walls, making wines with dark inky color and a tannin profile suitable for extended aging. BIG RED also produces a great mouthfeel due to the significant production of polysaccharides and glycerol. It is also tolerant to higher alcohol levels making it ideal for those grapes that need to stay on the vine just a little longer to get full phenolic ripes with smooth tannin profiles. So lets recap... emphasizes berry fruit with many varietals, produces dark color, extracts a full array of tannins suitable for extended aging, makes wines with great mouthfeel, and is resistant to higher alcohols. Is there a catch? No, but to get all that done BIG RED does love nutrients and you will need to feed it and pay attention to it during fermenation. This is a strain where you would ideally know your Free Available Nitrogen levels that you could base a nutrient schedule around. Absent those numbers or a history with the grapes you are fermentiing, we would suggest you start with hydrating with Fermstart, feeding with FermFed DAP free at the onset of fermentation and feeding again with regular Fermfed after 1/3 sugar depletion. BIG RED is a very low producer of H2S when nutrient demands are met. The perfect strain if you want to make amazing reds. Not the perfect strain if you have a vacation planned during the middle of fermentation and are going to ask your neighbor to punch down...we hear it all!. Because this strain respects varietal character it can be used for a broad spectrum of red grape varietals. Perfect of courese for those Bordeaux varietals ilke Cabernet Sauvignon, Cabernet Franc, Petit Verdot and even Merlot. Also our first choice for Nebbiolo and some bigger style Sangiovese and Pinot Noir. Start Time: Fast Alcohol tolerance: 16%+ Nitrogen demand: high Yan Requirement @ 23 Brix: 270ppm Production of volatile acidity: Low Production of SO2: Low Ease to Ferment with MLF: Average Yeast type: Cervisiae Killer Factor: Neutral Malic Acid Consumption: Average Optimal Fermentation Temp: 65–85°F Proper yeast hydration helps ensure a healthy fermentation.

Polyclar VT (PVPP)
5 reviews

A non-soluble clarifier that removes both haze causing polyphenols as well as yeast cells. Mix 2 Tbls (or 5 g) with one cup of sanitized warm water and gently stir into five gallons beer. Let stand for a few days and rack off. Polyclar VT is a coarser grade of PVPP (140 micron particle size), optimized for addition to vessels, where faster settling is required. The larger particle size also facilitates settling of the stabilizer, allowing the majority of the product to be left behind with the lees at racking. A typical contact time of between 3 to 10 days is required, although there are no adverse effects from leaving Polyclar in contact with the wine for longer periods. For wine use .5 to 2.5 grams per gallon depending upon severity of problem and desired affect. A rough approximate of weight is 1 tsp = 1.1 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.
