    Dry Wine Yeast - 3001

    Isolated, studied and selected from the prestigious Côte de Nuits terroir in Burgundy during a three-year research project by Laboratory Burgundia Oenologie in Beaune, France. The goal of this selection program was to find a dominant natural yeast strain from a traditional “cold soak” that would elaborate intense, complex and balanced Pinot Noir varietal character. The 3001 strain stood out from other strains. Wines made with it were noted for fruit and varietal characters that were both elegant and complex. This yeast has moderate nitrogen demands but will benefit from proper nutrition and aeration, these factors becoming increasingly important as your potential alcohol content rises above 13%. This strain is tolerant to standard SO2 additions and low temperatures (down to 12°C/54°F) for a steady and reliable alcoholic fermentation following cold soak. The 3001 yeast is specifically for high quality cold soak Pinot Noir destined for aging.   Click here for a PDF of the MoreWine Manual on re-hydrating wine yeast.

    CellarScience® FLORAL Dry Wine Yeast | Premium Wine Yeast

    Very low H2S producer which naturally allows fruit to shine through Cerevisiae/Bayanus hybrids strain Huge aromatics of floral and Citrus FLORAL is a natural hybrid between Cerevisiae and Bayanus allowing it to ferment at lower temperatures. Its famous for producing a wide range of flavors to add depth and complexity to any wine. FLORAL cannot assimilate sulfur which greatly reduces H2S making it an easy yeast to see through fermentatoin. Low H2S and volatile acidity part of the secret to emphasizing fresh fruit flavors. The production of phenylethyl alcohol and its derivative ß-phenylethyl adds sweet floral notes. Phenylethyl alcohol also helps extract thiols due to their similar polarity, contributing even more to citrus and floral flavors. A hugely aromatic yeast that is easy to ferment. Great for any whites or fruity reds where a floral charateristic is desired. First choice for Italian whites like Pinot Grigio. Can ferment down to 55F.   Start Time: Average  Alcohol Tolerance: 15%  Nitrogen Demand: Low  YAN Requirement @ 23 Brix:  200 ppm  Production of volatile acidity: Very Low  Production of SO2: Low  Cap/Foaming:  Very low  Ease to Ferment with MLF: Average  Lees Aging: Good Choice    Yeast Type: Hyrbid Bayanus/Cervisiae Optimal Fermentation Temp: 50–65°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® LUSCIOUS Dry Wine Yeast | Premium Wine Yeast

    Autolyzing, quick release of polysaccarides such as mannoproteins Top choice for sur lie aging Ability to ferment cold for clean flavor with emphasis on mouthfeel and toastiness of sur lie aging When fermented warmer exoctic tropical flavors shine Frequently used to make luscious Chardonnays and similar white wines Luscious Chardonnays with creamy mouthfeel and deep complexity... if that is your end point, LUSCIOUS is your starting point. LUSCIOUS can be fermented at different temps depending on your style preference. Ferment it cooler, it can handle it, and put the emphasis on the creaminess and the toasted champagne-like complexity of sur lie ageing. Or crank it up a bit warmer and add in some more tropical notes, your choice. However the magic of LUSCIOUS really happens after fermentation when this yeast goes naturally goes nuclear, implodes and breaks open its cell walls, during a process called autolysis. Polysaccharides such as mannoproteins are released into the wine... and man, it's all about those mannoproteins creating that rich, creamy mouthfeel that so many Chardonnay drinkers seek out. The silky richness is emphasized even futher by sur lie aging, aging on clean lees for a period of time, in either tank or barrel. Being a low producer of SO2 it is naturally great candiate for later malo-lactic fermentations. Now that we have painted a picture try putting this marketing wizardry on your next label "The 10-40w viscosity of this wine is due to it being loaded with mannoproteins from the guts of exploded yeast cells". Maybe leave us out of the wine marketing department but we do know a winning yeast when we taste it. #1 for this style of Chardonnay but also a top choice for Viognier and other whites. Optimal Fermentation Temp: 55–68°F Start Time: Average  Alcohol Tolerance: 14%+ Nitrogen Demand: Average YAN Requirement @ 23 Brix:  245 ppm  Production of volatile acidity: Average  Production of SO2: Low  Cap/Foaming:  Low  Ease to Ferment with MLF: Good  Lees Aging: Best Choice     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.

    CellarScience® BOUQUET Dry Wine Yeast | Premium Wine Yeast

    Produces ß-glucosidase to cleave terpenes Floral, Rose, Citrus flavors Will not produce volatile phenols Best choice for Muscat/Moscato & Gewurztraminer. Also great for Sauvignon Blanc, Riesling and Viognier Those floral, rose, citrus, and stone fruit aromatics are bound all up in terpense in your grape skins and you know, they would really like to get out. It's your job to free them, package them in a bottle, and eventually let them waft out of a wine glass and into the nasal cavity of someone who appreciates excellence. We can help you do this. If you are making a higly aromatic white such as Muscat, Gewürztraminer, Viognier, Sauvignon Blanc or Riesling this is the ideal yeast. BOUQUET is known for its production of the enzyme ß-glucosidase which liberates aromatic compounds by cleaving terpenes from the sugars that bind them and releasing their goodness. This yeast will turn these certain grape varietals from ordinary white wines to highly aromatic, very special white wines that smell and taste amazing. The type of wine where 'stuff' wafts out of the glass! Also interesting is that most yeasts have the potential to produce phenolic off flavors, which in high quantities produce a paint like aroma (yuck!), if the conditions are less than ideal. However, BOUQUET is POF (phenolic off flavors) negative and will synthesize phenolic off flavors, eliminating that risk. This is a great yeast to co-ferment with Luscious for added complexity. Additional Fermfed nutrient is recommended at the start of fermentation due to the short lag phase of this strain. Due to such a rapid period of growth, the yeast cells require higher levels of nutrients to ensure a healthy fermentation. If you have had your wine tested and know your Yeast Available Nitrogen (YAN) follow our CellarScience nutrient feeding schedule accordingly. If you don't know your YAN we recommend hydrating with Fermstart, feeding with FermFed at the onset of fermentation and feeding again with regular Fermfed after 1/3 sugar depletion. Normally the feeding at the onset of fermentation would be with Fermfed DAP free but in this case BOUQUET can use the extra DAP kick that Fermfed provides.   Start Time: Fast    Alcohol tolerance: 14%    Nitrogen demand: Very High  Yan Requirement @ 23 Brix: 340 ppm    Production of Volatile Acidity: Low    Production of SO2: Average  Cap/Foaming: Average  Ease to Ferment with MLF: Low    Malic Acid Consumption: Average    Killer Factor:  Positive (though is able to coferment with Luscious) Yeast Type: Cerevisiae Optimal Fermentation Temp: 50–80°F   Proper yeast hydration helps ensure a healthy fermentation.

    CellarScience® CITRUS Dry Wine Yeast | Premium Wine Yeast

    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.

  • Encapsulated Wine Yeast - ProElif QA23 (83 g)

    ProElif QA23 Encapsulated Wine Yeast (83 g)

    1 review

    ProElif QA23 is a double encapsulated yeast product developed by Proenol for secondary fermentations. The yeast cells are double encapsulated in an alginate bead. The beads can be directly inoculated into the bottle (eliminating the need to prepare a starter culture). This helps ensure control of the number of cells per bottle. Upon fermentation completion, the beads have a greater density than the wine and will quickly drop to the neck of the bottle when inverted. The beads accumulate more tightly than traditional riddling, therefore less wine is lost during disgorging. Traditional freezing and disgorging methods are used to finish the process. The use of ProElif QA23 results in a fresh sparkling wine. If greater yeast character is desired, you may make changes to the base wine with this in mind. For example, ProElif QA23 has been used with Opti-WHITE treated base wine with good results. The base wine must be stable to avoid agglomeration of the beads which could cause subsequent difficulty during disgorging. All of these parameters act in synergy with one another. It is critical to manage them together. If one parameter is over the limit, try to compensate with the others or ferment at a higher temperature. Use at a rate of 2g/L.  For full directions see the handout in the documents tab above.    FOR PROELIF QA23 TO BE SUCCESSFUL, THE BASE WINE SHOULD FALL WITHIN THESE PARAMETERS: Alcohol ≤ 11.5% (v/v) Free SO2 ≤ 15 mg/L pH ≥ 3.0 Free Assimilable Nitrogen ≥ 100 mg/L Calcium ≤ 80 mg/L Protein Stability = stable Tartrate Stability = stable Fermentation Temperature >  12°C(54°F)   Recommended Dosage 1.5-2 g/L 1.0-1.5g/750 mL bottle

    CellarScience® LiquiBody | Gum Arabic Solution

    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.

    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.

  • Encapsulated Wine Yeast - ProRestart Uvaferm 43 (83 g)

    ProRestart Uvaferm 43 Encapsulated Wine Yeast - (83 g) & 1 mesh bag

    4 reviews

    ProRestart and ProDessert contain yeast cells encapsulated within Alginate (natural polysaccharide extracted from seaweed) that are also acclimatized to alcohol and other harsh conditions. Unlike regular dry yeast, our encapsulated yeast are pre-conditioned to harsh conditions such as high sugars or high alcohol. They are a great choice for finishing stuck fermentations or fermenting dessert wines. To use, the beads are placed in a nylon bag and suspended in the ferment. The vast majority of the yeast stay trapped within the alginate beads. When they have completed their task, the bags are removed from the wine with few residual yeast cells from the culture being left behind. Though there may still be indigenous yeast present, use of the encapsulated yeast significantly reduces the amount of SO2, sorbate or tank chilling that are necessary to arrest fermentation. Sanitizable weights, such as stainless fittings or marbles, are placed in the bag to keep the bag submersed throughout the fermenation process. 83 Grams will treat 100L or 30 gallons of stuck wine. Works quickly due to preconditioning and direct addition into a stuck or sluggish fermentation. This is much, much easier than traditional restart methods. Decreases spoilage risks due to its rapid fermentative activity and helps avoid excessive SO2 additions. Decreases risks related to color loss from oxidation. Preserves the flavor of the wine due to rapid sugar consumption without volatile acidity increase or other spoilage problems. Use 83g per 30 gallons. Culture can be transferred to next barrel after first barrel is finished. Comes with nylon mesh bag and full set of instructions.

    CellarScience® GSH Naturale | Preserves Terpenes & Thiols

    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.

    CellarScience® CellarTan F | Fermentation Tannin

    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.

    CellarScience® Easy Sur Lie | Boost Body & Richness

    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.

  • CellarScience - Red Wonder - PLACEHOLDER

    CellarScience® Red Wonder | Boost Aroma | Lock In Color

    Enhances fruit and chocolate-like aromas in red wines Helps stabilize color Our selected blend of SIY's, Ellagic Tannins, and a touch of Gum Arabic Added at the end of fermentation or the beginning of aging Red Wonder was developed to add fruit and chocolate flavor to red wine. It brings the body and richness of sur lie aging with the amazing impact of ellagic finishing tannins. The ellagic tannins in this blend were selected for their ability to impart chocolate flavors into the wine. Red Wonder is a blend of specially inactivated yeast (SIY), elected ellagic tannins, and a little bit of LiquiBody Gum Arabic. In addition to body and flavor this product helps reduce the need for SO2 and also helps to lock in color. You certainly could select an SIY, like our CellarScience Easy Sur Lie and then trial them with different ellagic tannins along with LiquiBody. But we've worked in small wineries and we know you are busy, so we've done that trialing for you and selected the blend that most often turned out really exceptional red wines. Directions: Use at the rate of 0.4 to 1.5 g per gallon of wine. Rehydrate in warm water or wine for 30 minutes and then stir directly into the tank or barrel. Once fully mixed it doesn't need any further stirring. We recommend starting with dosage of 1 g per gal (0.25 g per liter) and adjusting on further batches as needed.

    CellarScience® Enzo Red | Enzyme Blend for Red Wine

    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.

    CellarScience® Killazyme | Inhibits Lactic Acid Bacteria

    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.

Wine Yeast Inoculation Rates:
The recommended amount of wine yeast needed for a healthy wine fermentation is governed by two elements; 1) the initial ºBrix (starting sugar content) of the must, and 2) the factors of the fermentation itself:

1) Assuming that proper wine fermentation management will be followed to keep the wine yeast as stress free as possible (ex: nutrients will be used, temperature and pH will be within acceptable ranges for the chosen strain, etc.), it is recommended to adjust the yeast inoculation rates based on the initial ºBrix of the must:

  • 24 ºBrix or below, 1 gram of wine yeast/gallon of must is recommended.
  • 25 ºBrix or above, 1.25 grams of wine yeast/gallon of must is recommended

2) Even at “normal” sugar levels of 24 ºBrix and below, a lack of sufficient nutrients, uncontrolled temperature spikes, inhibitory factors from residual late-season vineyard treatments or even spoilage compounds from mould and rot in the fruit can each contribute to stressing the yeast population during fermentation. As a result, a smaller percentage of healthy wine yeast will actually make it to the end of the fermentation and the wine will be at a greater risk of becoming sluggish or even stopping fermentation before the sugars have been consumed. Therefore, if the winemaker knows that the yeast will be placed in a potentially stressful situation, even if the sugars are in the 24 ºBrix and below, then the initial dosage rate should be bumped-up to create a ‘safety in numbers’ kind of scenario (from 1 g/gal to 1.25/1.5 g/gal).

(Please note that this larger dosage rate does not take the place of proper fermentation management, it only compliments it by raising the numbers a little more in the winemaker’s favor. True, you may have more wine yeast now, but you will still have to feed and care for them to avoid the usual H2S problems! For optimum wine yeast health, we recommend following the protocols as laid out in our Wine Yeast Re-Hydration and Nutrient Regimen Manual!)

Which Wine Yeast is Best?:
Each wine yeast has its own personality and depending on your winemaking style and the specific grape varietal you are working with there may be more than one that would make a really nice wine! To help you narrow the field a little (from the 35+ strains we carry), MoreWine! has created our Yeast & Grape Pairing Manual. The guide lists the top recommended wine yeasts for each grape varietal and lists the specific attributes each yeast gives for that particular grape varietal.
