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.

The ideal yeast for producing a very neutral, clean base for hard seltzers, canned cocktails, further distillation, etc.  Works with malt or sugar fermentations Includes nutrients and pH buffers to keep fermentation humming to finish  Able to handle high levels of ethanol and osmotic pressure Ferments clean up to 80°F ​Our motto is to Empower Your Creative Vision. Origin is a unique style of yeast used to create a neutral alcoholic base that acts as the Origin upon which you layer other flavors. Perfect for Hard Seltzers, Canned Cocktails, and whatever else you can dream up. Also great for neutral washes designed for distillation and tough to ferment honey-based mead fermentations. Works on both sugar, honey, and malt-based fermentations. The secret sauce is a very neutral, high alcohol tolerant yeast combined with nutrients and pH buffers. The non-urea-based nutrients help the yeast in simple sugar mediums naturally low in nutrients. pH buffers ensure a high enough pH to allow the yeast to run to completion in even the toughest of situations. The yeast strain used in Origin is a very low producer of H2S and fruity esters resulting in a clean final product. Origin stays clean at higher fermentation temperatures up to 80°F. Origin could technically be called a Turbo Yeast being packed with nutrients. However, we don't like that association as many turbo Yeasts are not selected and assembled for quality and flavor but rather price and speed. Turbo Yeasts also do not include pH buffers. Origin will work with all commonly used sugars, including sucrose, dextrose, and liquid invert sugar. When fermenting wort from malted barley, use our Brutzyme Glucoamylase Enzyme to break down α-1,4 and α-1,6 glycosidic linkages of starch, dextrins, and oligosaccharides for a drier, more fully attenuated final product. Pilot batches should always be performed to find the optimum final product for your further vision. Directions: Add 10 to 20 g per gal (2.5 to 5 g per liter) directly into your fermentation with no hydration required. Ferment between 65 to 80°F (18-27°C). We recommend starting with a dosage of 15 g per gal (4 g per liter) and adjusting as desired in future batches.

Easily added to mash water to reduce oxidation in finished beer Scavenges oxygen in mash water Reduces Lipoxygenase (Lox) activity in malt which reduces trans-2-nonenal stale/cardboard flavors in beer Reduces hot side aeration Results in beer with fresher flavor and longer shelf life Oxblox 3D is a specially formulated blend of gallotannins, ascorbic acid, and metabisulphite that is added to your strike water right before mash-in. It dissolves easily and is extremely useful to reduce oxidation during the mashing process. Through multiple actions, it reduces dissolved oxygen levels and helps inhibit the lipoxygenase enzyme found in malt that is infamous for causing downstream wet paper / cardboard flavors attributed by the (E)-2-nonenal compound. Oxblox 3D has minimal impact on pH but may lower pH levels by 0.2-0.4 in both the mash and the finished beer. You may not always notice stale flavor compounds in beer when present, especially at low levels. But when removed, the beer can smell and taste fresher. Beer treated with Oxblox also has an enhanced shelf life, staying fresher for longer. Overall, Oxblox 3D is a low cost, easy-to-use addition to help you brew better tasting beer that lasts longer in keg, can, or bottle. Use: Mix 0.2 to 0.4 g per gal (0.05 to 0.1 g per liter) into your strike water directly before dough-in. We recommend starting with a dosage of 0.3 g per gallon of strike water (0.08 g per liter of strike water) and adjust as desired in future batches.

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.

Unique amino acid blend activates Ehrlich pathway causing beer and wine yeast to produce tropical flavors Contributes complexity to beer styles like Hazys where tropical flavors are desired. Pairs perfectly with CellarScience HAZY Yeast Contributes tropical complexity to Sauvignon Blanc and Viognier wines when used in conjunction with CellarScience CITRUS Wine Yeast Enhance tropical flavors in your beer or wine with CellarScience Tropic Thunder. By changing the amino acid mix you feed your yeast you can influence the final flavors yeast produce. To understand why, we have to first explain the Ehrlich pathway which was discovered over 100 years ago by German Biochemist Felix Ehrlich. Yeast absorbs and breaks down a specific set of amino acids very slowly over the course of fermentation. The yeast cells incorporate the amino group into their cell structure, leaving an alpha-keto acid. This acid is turned into fusel alcohol by the yeast and then returned back out into the wort. This production of fusel alcohols via the breakdown of specific amino acids is called the Ehrlich Pathway. For Beer Fusel alcohol may scare you as a brewer... we get it, you are trained to avoid these! But certain fusel alcohols actually have a really positive effect on the final beer flavor. The idea behind CellarScience Tropic Thunder is we have selected specific amino acids that when fed to your yeast will result in the production of a small amount of fusel alcohols that contribute to the tropical flavors of mango, pineapple, and coconut. Tropic Thunder nutrient is often used to help create complexity in hazy IPA, but feel free to use it in any style where tropical flavors would be welcome—you are only limited by your imagination! When used in beer, Tropic Thunder can replace your typical yeast nutrient as it is itself an organic, DAP-free nutrient. If you typically use a complex nutrient that includes DAP, you can continue to add it separately as normal. For Wine Tropic Thunder is perfect for Sauvignon Blanc, Viognier and other select styles where tropical fruit flavors are part of your vision. In addition to selecting a thiol releasing yeast strain such as CellarScience CITRUS, Tropic Thunder can help bring complimentary tropical fusel flavors via the Ehrlich pathway. As a part of the overall mix, along with thiols and terpenes, the complexity of Sauvignon Blanc or Viognier is enhanced. Tropic Thunder can also be used in select Chardonnays or any white wines where tropical mango and pineapple flavors are desired. When added at the rate of 0.6 to 2 grams per gallon, Tropic Thunder contributes 3 to 12 ppm of YAN. When using CellarScience FermFed or FermFed DAP Free nutrient blends to power your fermentation, we recommend adding Tropic Thunder on top of these additions. Use: For beer or white wine add 0.6 to 2 gram per gallon (0.15 to 0.5 grams per liter) directly into the fermenter at the start of fermentation. Perform bench trials to determine optimal usage or start with a dosage of 1.2 g per gal (0.3 g per liter) and adjust as needed on future batches.
