SilaFine is an easy-to-use, vegan friendly fining agent that quickly creates crystal clear beer by removing yeast and haze-forming particles. SilaFine is a unique, negatively charged silica sol fining agent that binds with and positively charged haze active proteins and polyphenols as well as yeast cells. SilaFine does not target foam active head forming proteins, leaving beer foam in glass unaffected. Use: Add 10ml or 1 tbsp per 5 gallons of finished beer. Gently rouse the beer to fully disperse the clarifier. Most effective on beer that has been chilled below 39°F. If the beer has not cleared after 24 hours, a second dose can be added. SilaFine should be stored cool, but do not freeze. Whirlpool: SilaFine can also be used in the whirlpool at a rate of 0.5-1ml per gallon to achieve a quicker and more compact sedimentation in the kettle.   Additional Notes: SilaFine is based on a special selection of commercial grade amorphous silicon dioxide, also known as silica sol, at a concentration of 30%. Silica sol is known by a few names in brewing including colloidal silica, acidified silicates, silicon dioxide, and silicic acid. Unlike some other silica sols, SilaFine is not treated with aluminum oxide. SilaFine is a pure mineral and complies with Reinheitsgebot German beer purity law. Do not freeze. Store in a cool, dry place away from direct sunlight and heat.   The recommended shelf life is 12 months from the date the package is opened.   Allergen Free GMO Free

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.

Due to high demand, the 8 oz is currently out of stock. Be the first to receive your items by placing a pre-order today. We will automatically ship this to you when we receive more inventory. Reduce Diacetyl production during fermentation or dry hopping with ALDC from CellarScience. ALDC, or alpha acetolactate decarboxylase, is a helpful enzyme that can be added at yeast pitching or along with your dry hops to limit the production of Diacetyl to protect your finished beer from off-flavors and reduce the conditioning time needed before its ready to bottle or keg. Commonly used to combat hop creep, the result of dry hops with trace amounts of sugar leading to additional fermentation activity, resulting in more Diacetyl production and requiring more conditioning time.  Use: Available in 1 oz dropper bottle or 8 oz bettix bottle. Add to fermenter at time of yeast pitching or dry hopping at a rate of 1 dropper full per 5 gallons or 3 mL per bbl. 1 oz contains approximately 35 doses for 5-gallon batches, or enough to treat approximately 10 bbls. Additional Notes: Although commonly added to heavily dry hopped beers, using ALDC during fermentation can benefit any beer style by reducing Diacetyl production. Brewing hops all contain the naturally occurring enzyme AMG or amyloglucosidase which breaks down long chain sugars into simple sugars that yeast can ferment. The reason hop creep is a relatively new phenomenon is due to the changing ways in which hops are dried and processed. As brewers started to demand more aromatics from their hops, growers began to lower the kilning temperatures to preserve volatile oils. This led to higher levels of AMG left on the hops as well, where they were previously denatured at the higher kilning temperatures. With more AMG present on the hops, dry hopping now leads to more fermentation activity and higher levels of Diacetyl produced after the primary fermentation is complete. Although the simplest remedy to hop creep is time—waiting for the yeast to naturally clean up the extra Diacetyl—ALDC is a great way to reduce conditioning time and the risk of off-flavors in your finished beer. The recommended shelf life is 12 months from the date the package is opened.

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.

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.

Due to high demand, the 8 oz is currently out of stock. Be the first to receive your items by placing a pre-order today. We will automatically ship this to you when we receive more inventory. 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.

Brutzyme by CellarScience is an enzymatic blend used to produce dry beers. Perfect for making Brut IPAs or any other style where a low gravity, dry finish is desired.  Amyloglucosidase, alpha amylase, and pullulanase combine to enable the hydrolysis of starch and dextrins into fermentable sugars that yeast can ferment. Use: Add 1/4 tsp per 5 gallons at the beginning of fermentation. Brutzyme can be added directly to the fermenter at the same time yeast is pitched. Works best at a temperature range between 50-68°F and a pH of 4-5.5. Additional Notes: Brutzyme is a mix of amyloglucosidase, a-amylase, pullulanase and other dextrinases capable of breaking down the α-1,4 and α-1,6 glycosidic linkages of starch, dextrins and oligosaccharides completely into fermentable sugars. Brutzyme is extremely affective for making very dry beers, especially Brut IPAs. Store at temperatures under 70°F. The recommended shelf life is 12 months from the date the package is opened.
