Wine Yeast, Malolactic Bacteria & Additives

An interesting yeast which can reduce the sensation of acidity and astringency in red wines from difficult conditions such as high acidity. Delicate fruit-forward aromas of cherry, blackberry, plum, and ripe fruits will be present in wines fermented using this yeast. Floral characteristics such as wild violet, as well as spice and vanilla have also been noted. This yeast is perfect for Sangiovese, hybrids, roses, and other light reds. The RBS strain will work well in conjunction with malolactic fermentation. Best fermentation results within 61-82°F. This is a moderate fermenter with medium nutrient requirements, capable of withstanding alcohol content up to 16%. Click here for a PDF of the MoreWine Manual on re-hydrating wine yeast.

Big mouthfeel from high glycerol /polysaccharide /mannoproteins Flavors of Cherries, Raspberries, Figs, Jam, Red currant High alcohol tolerence Low nutrient needs Perfect for Syrah, Zinfandel, Pinot, Merlot, Malbec, Sangiovese, Grenache Our go-to choice for those reds originating from the Cote du Rhone in France such as Syrah, Grenache, and Mouvedre. Also a top choice for Zinfandel, Sangiovese, Malbec, Merlot, and Pinot. Induces flavors of ripe cherries, raspberries, red curant, figs and jam. Due to its production of glycerol and release of mannoproteins it produces full bodied, rich red wines. PURPLE has a very low production of SO2 which is favorable for an easy malolactic fermentation (MLF) post fermentation. PURPLE is also an easy to ferment yeast with a low nutrient needs which is the opposite of our Big Red strain. It also has a "killer" quality and naturally inhibits unwanted bacterial or wild yeast growth during fermentation.   Start Time: Slower    Alcohol tolerance: 15%  Nitrogen demand: low  Production of volatile acidity: Low    Production of SO2: Low Ease to Ferment with MLF: Average  YAN Requirement @ 23 Brix: 200 ppm    Malic Acid Consumption: Low  Yeast Type: Cerevisiae Optimal Fermentation Temp: 65–85°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.

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.

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. 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.

Emphasizes red berry fruit flavors  High color extraction Makes wines that do not require extended aging Med-High nutrient need  Top choice for Zinfandel, Sangiovese, Pinot, Merlot   Our most popular red yeast is a perfect choice for Pinot Noir, Zinfandel, Sangiovese, Merlot and other reds where you want to emphasize red fruit flavors. When compared with BIG RED or PURPLE, RED is less about structure and body and more about fruit. Fantastic by itself if you plan to blend separately fermented lots back together. RED is a great choice to contribute red berry flavor. Also known to help produce intense color. Also a great choice for Cabernet, Syrah and other traditinoal big red varietals where you would like to emphasize fruit over structure and body. Because RED ferments cleaner than most yeast at high temperatures, it is the perfect choice if you are fermenting in a warm environment and do not have temperature control.  It does not produce much SO2 so it is a great choice for easier ML fermentations   Start Time: Average Alcohol tolerance: 16% Nitrogen Demand: Med  Yan Requirement @ 23 Brix: 250ppm Production of volatile acidity: low  Production of SO2: Low Ease to Ferment with MLF: Good    Yeast Type: Cerevisiae    Killer Factor: Neutral    Malic Acid Consumption:  Average Optimal Fermentation Temp: 65–85°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.

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.  New Liquid Oak Tannins produced by Toasted Oak Inc. are water based, French Oak Tannin concentrates, designed to easily integrate smooth and flavorful oak character into a wine, without the cost or hassle of traditional oak barrels. While powdered tannins are similarly cost effective, there will be some loss of flavor and texture due to the high temperatures necessary to evaporate all liquid out. Liquid Oak Tannins are the perfect balance of oak barrel flavor, and pure tannin cost. Aside from the beneficial flavor impact of these products, they are also easier to add to the wine and assure even dilution. These Liquid Oak Tannins are for red and white wines. Please do bench trials carefully when considering their use in white wines. Additions may cause filterability(and stability) changes. Do not exceed 30% of normal red wine dosing for white wines. Fruit Enhancer Plus has more proanthocyanidic tannin components to emphasize a ripe berry character and a fruity, aromatic style.  It has to be carefully dosed as it will have a strong influence on the existing character of the wine.  Works best on red wine to accentuate a ripe berry character (Black Cherry character). A 4 oz bottle of Fruit Enhancer Plus will treat 125 gallons of wine with a low dosage, or 47 gallons at a high dosage.  Please see the Documents tab above for additional information as well as Bench Trial procedure.

Often used with isinglass, bentonite, gelatins, and other organically derived fining agents to help compact the lees, Gelocolle is a liquid solution of suspended silica that is used during fining to help improve settling. Gelocolle also helps to limit the risk of over-fining when used in conjuction with other fining agents. Gelocolle can also be used to remove excess protein in both red and white wine, thereby improving their filterability. Gelocolle is completely inert and will not add any flavor or aroma to the wine. To Use Add Gelocolle 1 hour after the fining agent. Mix well to ensure homogenization. Recommended Dosage: In general, use Gelocolle at a rate of 1 mL Gelocolle per 1 g of the fining agent you are aiding. For protein removal use 5 ml Gelocolle per gallon of wine. Note: When using Gelocolle with a gelatin fining, use 1.0 mL of Gelocolle to 1.0 mL of gelatin. Once opened use immediately. Best stored at 50-68 F (10-20 C). Gelocolle solidifies irreversibly when frozen.

This product is a direct replacement for our FIN74 - Ichtyocolle. Recommended for whites, roses and fruit wines, Cristaline Plus is a blend of isinglass (fish-derived protein) and citric acid stabilized with SO2. Cristaline Plus has a strong positive charge which makes it very effective at improving the clarity of a wine (even those that are made from botrytised grapes). As an added benefit, Cristaline Plus can help improve the filterability of a wine. Cristaline Plus is not sensitive to cold temperatures and may be slow to finish settling. The use of Gelocolle (FIN64) an hour after the addition of Cristaline Plus will help speed the settling process and create a more compact lees. To Use: Dissolve Cristaline Plus in 150-200 times its weight (75-100 mL) of clean, warm water (59-68 F/15-20 C) Let mixture swell for 3 hours If the solution is too viscous add additional warm water Add the solution quickly into the whole volume of wine to be treated while stirring and mix well to distribute the Cristaline Plus evenly throughout the wine Rack as soon as the lees are well settled (wait 72 hours before filtering or allow 8-10 days settling before racking) Dosage Range: 15-30ppm (mg/L)

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!

Caseinate de Potassium, formally Caseine Soluble, is a concentrated, powdered form of Potassium Caseinate produced from milk. Helps eliminate oxidized phenolic (brown colored) and bitter compounds in white wines, rose wines, fruit wines, and meads. Caseinate de Potassium can be used preemptively in the must or as a curative step on finished wine. Recommended Dosage: In Juice: 1.9-3.8 g/gal (500-1000 ppm) In Wine: 0.8-3.8 g/gal (200-1000 ppm) Preparation For Use Add the pre-measured amount of Caseinate de Potassium to 10 times its weight of cold water (do not use juice or wine). Allow the solution to swell for 4 hours Stir to dissolve any lumps When completely dissolved, add the mixture slowly to the juice or wine while stirring continuously (for juice, add Caseinate de Potassium before settling). Once added, strongly stir the entire wine volume to get the Caseinate de Potassium to integrate with the wine. Once Caseinate de Potassium has been dissolved, use the preparation within 2 hours. Minimum contact is 2 days, maximum 15 days. The amount needed for your specific wine is best determined by a bench trial. A rough approximate of weight is 1 tsp = 2.3 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.

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. 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.

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.

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. 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.
