Add to Red Wine Fermentation on the skin Binds with anthocyanins and stabilizes color Improves mouthfeel and body Mix of both ellagic and proanthocyanidin tannins CellarTan F is designed to be added to red wine fermentations where it binds color, improves body and mouthfeel, and softens the overall tannin profile. Used during the early stages of fermentation when anthocyanins are being released from the grape skin in the presence of alcohol and need to be stabilized for long term color retention. CellarTan F is a combination of ellagic tannins and proanthocyanidin tannins. Ellagic tannins are hydrolysable oak tannins that break down in wine. They react with grape skin derived phenolics to form flavono-ellagitannins which are hybrid compounds that play a key role in color stability while also softening the mouthfeel of your wine. Ellagic tannins also have potent antioxidant properties that reduce the need for SO2. Proanthocyanidin tannins, or condensed tannins, also contribute to color stability, taste, and mouthfeel. Through polymerization, anthocyanins cap the end of tannin chains to form stable color throughout the life of your wine. They also increase the body and structure of wine. Use: Dissolve 0.2 to 2 g per gallon (0.05 to 0.5 g per liter) in juice or water. Add to must at least 30 min after any SO2 addition and mix well. If you are unsure where to start within the suggested range, we recommend a dosage of 1 g per gallon (0.25 per liter) and adjust as desired on future fermentations.

Cleaves (Chops!) thiols releasing citrus, passionfruit, grapefruit, floral flavors Ferment at 58-61 for maximum enzymatic activity #1 Choice for Sauvinon Blanc. Also good for Viognier Oh thiols, you elusive magical compound. Nice try hiding behind Cysteine-4mmp, but CITRUS sees you. Cleaving thiols from other compounds is what CITRUS does, releasing the classic citrus, lime, passionfruit, and floral flavors that help separate styles like Sauvignon Blanc and Viognier from ordinary white table wine. Also can be used with Chardonnay , other whites, and is great for Rose. CITRUS can ferment at cooler temperatures but the enzymatic cleaving activity is highest at around 56-60F.  So if you like Zesty Grapefruit, lime, lemon peel, floral, and passionfruit flavors, CITRUS may be your yeast.  This yeast is good and perserving acidity so if you are working with whites from a warmer region that can be particularly helpful.     More on Thiols: Thiols are organic sulphur compounds that are resonsible for the most prized flavors in many white wines. 4mmp (black current), 3MH (Passion fruit, Grapefruit and Citrus) and 3MHA (Tropical Passionfruit, Rose)    Start Time: Average Alcohol tolerance: 14%+ Nitrogen Demand: low Production of volatile acidity: Average Production of H2S: Average Production of SO2: Low Ease to Ferment with MLF: Good Optimal Fermentation Temp: 53–73°F (Ideal for enzymatic activity: 56–60°F)   Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes.

Clearzyme by CellarScience is an enzymatic solution to create clear beer by breaking down haze causing proteins so they cannot later bind with tannins. Because it specifically targets only haze active proteins, it has no effect on flavor, aroma or head retention. Use: Add 1/4 tsp per 5 gallons at the start of fermentation. Works best at a temperature range between 50-68°F and pH of 4-6. Additional Notes: Clearzyme is a protease, or proteolytic, enzyme that partially or totally hydrolyzes peptide bonds in protein. The resulting protein fractions are then too small to bond with the polyphenols in hops. One of the huge benefits of Clearzyme is that it removes the need to cold crash, saving time and energy. Clearzyme also breaks down the Gluten protein that causes allergic reactions. Beers made with barley and wheat that have had Clearzyme added typically show gluten levels below 20ppm. Store at temperatures under 70°F. Immediately recap bottle after each use. The recommended shelf life is 12 months from the date the package is opened.

All the benefits of Sur Lie aging without the risks Luxurious, soft mouthfeel Perfect for your big body whites Helps reduce browning Produced from yeast cells and considered an SIY (especially inactivated yeast) CellarScience Easy Sur Lie offers all the benefits of doing a sur lie aging without the risk. Sur lie aging, often also referred to by the French term Battonage, is the process where wine is left on the original lees. or yeast, at the end of fermentation. Battonage specifically refers to the process of stirring lees back into solution over a few weeks to add body and richness to the wine. Exactly how it is done depends on the winemaker. Some choose to leave the wine on the gross lees while some choose to remove the wine quickly from the gross less and then stir up a clean version of the remaining yeast that settles out. Either way, there is some risk in this process of extracting some flavors you don't want while also potentially adding unwanted oxygen into the wine. During Sur lie the yeast cells are breaking down, releasing peptides, mannoproteins, and anti-oxidant amino acid proteins, and other yeast cell compounds. These compounds add that luxurious, soft mouthfeel to wine that is so desired. CellarScience Easy Sur Lie adds these compounds into the wine without having to take the risk and time/cost of doing an actual Sur Lie aging and stirring protocol. Easy Sur Lie also has some extra benefits. It helps prevent the formation of mercaptans, reducing potential sulfur compounds that can mask the full potential of your wine. It also functions as an antioxidant. Yeast at the bottom of naturally carbonated beer bottles is long known as an antioxidant that helps keep packaged beer fresher longer. Easy Sur Lie in your wine works in a similar way, supporting SO2 to help ensure freshness and reduce browning reactions. Can be added at the end of fermentation and throughout the aging process. Use: Mix 1.5 g per gal (0.4 g per liter) for best results. Add at the last stages of fermentation or early in aging for the furthest integration and best results.

Add to red wine fermentations on the skin  Releases aroma compounds, anthocyanins for color, and polysaccharides for mouthfeel Reduces necessary contact time / physical interaction normally needed for extraction Pectinase blend that breaks down cellulose and hemicellulose Enzo Red contains a selection of enzymes designed to promote deep, lasting color, structure, and aroma in fine red wines. Enzo Red is a blend of pectinases that will degrade both cellulase and hemicellulase, releasing anthocyanins and desirable skin tannins. It also releases aromatic compounds along with polysaccharides to help contribute to the aroma and body of your red wine. By breaking down pectins, Enzo Red helps with faster clarification and easier downstream filtering. Enzo Red can help to reduce the amount of punch downs or pump overs required. While there is no harm to keeping your existing schedule, it reduces the need for extended skin contact time, helps with extraction when an ideal punch-down schedule can't be maintained, and lessens the amount of time spent in pump over. For pump over in particular, this can be an advantage by lessening the shearing action on seeds that can occur when pumping must. Enzo Red is obtained from aspergillus niger and does not contain the enzymes cinnamyl esterase (production of barnyard flavors) or anthocyanase which is known to produce oxidized color hues in wine. Use: Dilute 0.04 to 0.15 g per gal (0.01 to 0.04 g per liter) into water and add directly into the crushed grapes or must. Perform bench trials to determine optimal usage or start with a dosage of 0.1 g per gal (0.025 g per liter) and adjust as desired on future batches.

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.

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?

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    The best way for to test for YAN is using a lab or a home testing solution like this YAN kit from Vinmetrica. 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.

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.

Foam Axe by CellarScience is a uniquely formulated anti-foaming agent that increases fermenter capacity and reduces the risk of kettle boil overs. By reducing surface tension, bubbles are Axed before they can form. Foam Axe actually increases head formation in the finished beer by retaining foam forming proteins that would have normally blown off during fermentation. Use: In the fermenter, add 1-2 drops per gallon at the start of fermentation. In the kettle, add 1 drop per gallon before the boil starts to help prevent boil overs. Additional Notes: Foam Axe is made from food-grade silicone and works by breaking up foam particles and dispersing surface tension. Foam Axe settles out of beer prior to bottling or kegging. Store cool and in an environment below 90°F. Do not freeze. The recommended shelf life is 6 months from the date the package is opened.

The perfect choice for fermenting fruit forward whites, roses, ciders, and meads. Because FRESH is a Bayanus strain it is able to ferment at lower temperatures, a nice option for producing cleaner more focused fruit flavors. Emphasizes stone fruit flavors. We almost named it Beauty and the Beast because once it starts fermenting it doesn't stop. Super easy to ferment with lower nutrient needs and a a very high alochol tolerance up to 16%. Many cider producers like this yeast for its ability to add those fresh and fruity flavors. Although easy to ferment, we still recommend our CellarScience nutrient regimen of Fermstart, FermFed DAP Free, and FermFed to increase fruit and floral flavors, while avoiding H2S production that can mask fruit.   Start Time: Fast    Alcohol tolerance: 16%    Nitrogen demand: low  YAN Requirement @ 23 Brix: 225 ppm  Production of volatile acidity: Very Low    Production of SO2: Low  Cap/Foaming: Very low  Ease to Ferment with MLF: Average    Malic Consumption: High  Yeast Type: Bayanus Optimal Fermentation Temp: 50–80°F   Proper yeast hydration helps ensure a healthy fermentation. For every gram of yeast, mix .25 g of FermStart yeast nutrient with 25 ml of sterilized tap water between 104–106°F/40–41°C. When water reaches 104°F/40°C, sprinkle yeast into water and stir gently. Allow the slurry to stand undisturbed for 15 minutes and then stir again. For every gram of yeast used add 25 ml of clean must to the yeast slurry and let stand 15–20 minutes. If necessary, use additional must to adjust yeast slurry to within 18°F of must temp before pitching. For a complete nutrient schedule sufficient for most fermentations, add 1.5 g of FermFed DAP Free per gallon of must at the first sign of fermentation and 1 g of FermFed per gallon of must after 1/3 sugar depletion.   Click here for a PDF of the MoreWine Yeast and Grape Pairing Guide.

CellarScience Glucabuster improves lautering and yield and makes any downstream filtering easier. First the highly concentrated β-glucanase break down the glucan formation that can lead to stuck mashes and slow run off. Then the included Xylanase and Cellulase break down the polysaccharide chains of arabinoxylan and cellulose. Together, all three enzymes help keep todays challenging mashes flowing right. Use: Add 1/4 tsp per 5-gallon batch at mash-in. Glucabuster works in a range of 120-185°F and ideally at a pH range of 4.7-7.0. Additional Notes: Endosperm cell walls are made up of non-starch polysaccharides, of which, in barley, β-glucans account for 75% with arabinoxylan (pentosan) and cellulose accounting for most of the rest. In wheat, the arabinoxylan content is higher. Glucabuster is composed of the cell wall hydrolases β-glucanase, xylanase, and cellulase, which break down the β-14 bonds in these polysaccharides. These enzymes can be equally important to their more famous starch degradation enzymes, α-Amylase and β-Amylase.  Glucanase, xylanase, and cellulase are naturally found in malt but decrease during the kilning stage of malting. Depending on your recipe, adding these enzymes is important to assist with lautering and later with filtering. Refrigeration is recommended, but store at least below 70°F. The recommended shelf life is 12 months from the date the package is opened.

Protects against oxidation Preserves Terpenes, Esters, and Thiols (3MH, 3MHA) during aging Reduces need for SO2 Improves color stability CellarScience GSH Naturale was designed for winemakers who want to take advantage of the benefits of Glutathione. Glutathione reduces browning in all wines but is especially useful in whites. In whites with higher levels of terpenes and thiols (e.g. Sauvignon Blanc and Viognier) GSH helps preserve fruity/floral aromas. It is also particularly helpful to produce natural wines or wines with less SO2. How it Works: Quinones are a class of compounds that can degrade wine by causing oxidizing reactions that lead to browning and the loss of desirable varietal flavors. Terpenes and Thiols are particularly prone to interact with Quinones. Instead GSH reacts with Quiniones creating a stable compound that does not lead to browning and a loss of flavor and aroma. GSH is a natural compound found in yeast cells and acts as a natural anti-oxidant that can be used in conjunction with SO2 or by itself in the case where the winemaker chooses to use low or zero quantities of SO2. GSH Naturale contains a high percentage of tripeptide glutathione along with other polysaccharides that have a positive impact on body, flavor, aroma. Usually used in conjunction with SO2 as an additional natural inhibitor of browning, GSH Naturale will have positive impact on color, wine, thiol, esters and terpene content throughout the aging process. Use: Add 0.4 to 1.5 grams per gallon (0.1 to 0.4 g per liter) directly into the wine. We recommend starting with a dosage of 1 g per gallon (0.25 g per liter) and adjusting as desired in future batches.

Prevent volatile acidity in fermentation before it happens Add at first signs of a problematic ferment to help limit the production of volatile acidity Avoid a malolactic fermentation (MLF) in White Wines Use as an insurance policy during barrel aging of Red Wines to reduce the risk of volatile acidity CellarScience Killazyme is a lysozyme that is used to control and inhibit gram-positive lactic acid producing bacteria including Oenoccoccus, Pediococcus, and Lactobacillus.  This is a tool winemakers can use throughout the winemaking process to limit bacteria contamination and the production of volatile acidity. Killazyme does not affect gram-negative Acetic Acid bacteria nor yeast.   Don’t Use Killazyme If You Are Coinoculating Yeast and ML When performing a “secondary” malolactic fermentation (MLF) we want lactic acid Bacteria to convert the harsher malic acid into lactic acid. Mostly MLF fermentations are done sequentially with the sugar fermentation being completed first followed by the MLF fermentation second. If you are doing a co-inoculation of yeast and lactic acid bacteria during the primary ferment, do not use Killazyme.   Use Killazyme to Prevent Volatile Acidity in Fermentation Killazyme can be added at the start of fermentation to limit lactic acid bacteria before it happens. Under certain situations lactic acid can use sugar or citric acid which it converts into acetic acid and volatile acidity. Killazyme is effectively used at the start of fermentation when you know or suspect a slow to start fermentation. This might be a result of a cold soak or those ferments relying on native yeast. Once your yeast starts to rip, the potential action of lactic acid bacteria is greatly suppressed and the need for Killazyme is reduced. At the back end of fermentation, slow, struggling fermentations caused by various reasons, such as temperature or high sugar, can cause bacteria to consume sugar and citric to produce acetic acid and volatile acidity. Additionally, if lactic acid bacteria fully converts the available malic acid the bacteria can pivot to sugar and citric product volatile acidity. In a problem ferment where the yeast are already struggling, volatile acidity acts as a double whammy suppressing yeast activity even further. If you suspect a problem finish, based on past experience or current conditions, Killazyme is a great tool to add at the start of fermentation Use Killazyme at First Signs of Problem Finish Killazyme can also be added at the first signs of a problematic ferment to help limit the production of volatile acidity. This reactive addition requires a heavier dosage than a preemptive addition as there is most likely volatile acidity already present.   Use Killazyme to Avoid MLF in White Wines When fresh, crisp white wines are desired, Killazyme can be added at the start of a white wine fermentation, or at any point in tank or barrel, to block lactic acid activity and prevent MLF. We still always recommend a sterile filtration for commercial whites before bottling to prevent a later MLF in the bottle. .  Killazyme is also great if you are going to be blending whites where one white went through and MLF and the other white did not.    Barrel Storage Protection of Reds After MLF is complete and you storing wines in barrel Killazyme is a great insurance policy to reduce the risk of volatile acidity.  Use: 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 immediately 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. You can make a 10% solution of Killazyme in water (100 grams per liter of water). However, we find the easiest method is to add the desired dry weight of Killazyme 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.

A classic yeast strain for Kölsch & Altbier beer styles. A neutral ester profile allows the beer to better express noble hops & malt character. Finishes dry with low levels of diacetyl. Every batch is PCR tested to ensure quality.  Dosage: Two sachets are enough to treat a 5–6 gallon batch. When calculating for larger batches, use at a rate of 2.25–3.25 grams per gallon of wort. We recommend rounding up by one full sachet rather than measuring out the yeast exactly. Direct Pitch or Rehydrate: KÖLSCH yeast is designed to be sprinkled directly onto the surface of your wort with no oxygenation required in the initial fermentation. Our aerobic growth process makes this possible by creating dry yeast with high viability and high sterol levels. KÖLSCH yeast is pre-loaded with essential nutrients to ensure a successful, complete fermentation. While not required, some brewers prefer to rehydrate yeast. To hydrate yeast, first, sanitize the yeast brick and scissors. Use 10 grams of sterilized tap water between 85-95°F (29-35°C) mixed with 0.25 grams of FermStart per gram of yeast. Sprinkle yeast on the water. Allow the slurry to stand undisturbed for 20 minutes, then swirl. Use small amounts of wort to adjust to within 10°F (6°C) of wort temperature before pitching. Ferment between 60-73°F (16-23°C). Optimum Fermentation Temp: 60-73°F Flocculation: Medium Alcohol Tolerance: 10-11% ABV Attenuation: 75-80% Similar Strains: WLP029, WY2565 Gluten-free

Adds mouthfeel and body to wines, seltzers, ciders, etc. Adds perceived sweetness without the concerns of adding residual sugar Helps lock in color by keeping anthocyanins in suspension in red wines Reduces the formation of tartrate crystals in white wine Makes bubbles in sparkling wine rise slower enhancing the appearance LiquiBody by CellarScience is a specialized, pre-liquefied Gum Arabic preparation that adds body and perceived sweetness while stabilizing color and smoothing tannic astringency. LiquiBody is made from high molecular weight polysaccharides which adds the perception of sweetness without having to stabilize residual sugar in your wine. The ability to add body and a little perceived sweetness has many applications. LiquiBody helps keep anthocyanin color compounds in solution, preventing them from precipitating out in the bottle. It is also particularly useful to help keep tartrates in solution when cold stabilization of white wine is not possible.  Popular Uses LiquiBody works really well in hard seltzers to add body and a slight sweetness. LiquiBody is added to sparkling wines to improve mouthfeel while increasing the appearance and fineness of the bubbles. Add perceived sweetness to any wine in your lineup to appeal to a larger portion of the population.  Filtering Add after rough filtration is finished and before or after sterile filtration. LiquiBody is suitable for use with a sterile membrane filter if your wine is very clean and you have prefiltered. If your wine is not prefiltered, and you already suspect you may have issues with sterile filtration, do not use LiquiBody. Dosage: LiquiBody is stabilized with potassium bisulfite which will add less than 1 ppm of SO2 into your final wine. Use: Add 0.75 to 5 mL per gallon. Perform bench trials to determine optimal usage or start with a dosage of 2 mL per gallon and adjust as needed on future batches. Works best at a temperature range between 50-68ºF and a pH of 4 to 5.5. Additional Notes: Once opened, partial bottles of LiquiBody should be refrigerated and used within 30 days. If a container is left open for longer than the suggested use, you can add 1000 ppm of SO2 to extend its life span.
