ELEVATE FERMENTATION - Step up your fermentation with Craft A Brew’s Yeast Nutrient. A blend of food grade urea and Diammonium phosphate (DAP), this product creates a nutrient rich environment for yeast.
HOW IT WORKS - Our food grade Yeast Nutrient keeps yeast healthy and productive throughout fermentation.
HOW TO USE - Simply add our Craft A Brew Yeast Nutrient to must or wort at the beginning of fermentation. We recommend you use 1 teaspoon of Yeast Nutrient per gallon.
BREWING RECOMMENDATIONS - This product is ideal for musts (unfermented wines) that are not naturally nutrient dense, like non-grape wines, meads or hard seltzers. Since beer malts and wine grapes are nutrient dense, yeast can thrive during fermentation...
CAMPDEN TABLETS FOR WINEMAKING - These tablets, composed of Sodium Metabisulfite, serve a myriad of purposes in the art of winemaking. They excel in crafting traditional grape wines, fruit wines, ciders and various other fermentations. The tablet form is...
HOW IT WORKS - Campden Tablets act as a sterilant, suppressing spoilage bacteria, like wild yeast, from growing in your wine. Winemakers will often add a tablet to the must (unfermented wine) 24 hours before pitching yeast. This provides yeast a clean...
SODIUM METABISULFITE - This versatile compound in winemaking, serves as a preservative when paired with Potassium Sorbate on bottling day. These tablets also effectively combat browning and oxidation, and can double as a solution for removing chlorine or...
USAGE RECOMMENDATIONS - For best results, use 1 tablet per gallon. SImply grind the tablet into a powder before using, which is easily done by pressing the tablet between 2 spoons. Adding half a Campden tablet for every 5 gallons or 20 liters of water...
FAST & MESS-FREE CARBONATION – Skip measuring priming sugar. These ready-to-use carbonation drops simplify bottling with no mixing, no boiling, and no cleanup required.
CONSISTENT RESULTS EVERY TIME – Each drop contains a precise amount of sugar, ensuring even carbonation across every bottle with no guesswork.
PERFECT FOR BEER, CIDER & MEAD – Ideal for carbonating homebrew beer, hard cider, and sparkling mead with reliable, consistent CO₂ production.
EASY TO USE – JUST DROP & FILL – Add 1 drop per 12 oz or 16 oz bottle. Add 2 drops per 22 oz or 32 oz bottle before filling. Cap and allow to carbonate per your recipe instructions.
ELEVATE FERMENTATION - Our Craft A Brew Irish Moss is essential if brewing clearer beer is your goal. This product is a kettle fining derived from seaweed, and a major source of carrageenan that’s used as a clarifier in home brewing.
HOW IT WORKS - Our Irish Moss essentially pulls proteins and small particles out of suspension during brewing for a clearer, less hazy finish.
HOW TO USE - Simply add our Craft A Brew Irish Moss on brew day with 15 minutes left in the boil. For the best results, rehydrate for 10 minutes in a small amount of cold water before adding to the kettle.
BREWING RECOMMENDATIONS - Irish Moss enhances cold break (protein coagulation) in the kettle for clearer beer. We recommend you use 1 teaspoon per 5 gallons.
EFFICIENT FERMENTATION - Craft A Brew’s packaged Fermaid K is a blended complex yeast nutrient that facilitates efficient fermentation by promoting yeast growth and reproduction. Its blend of nutrients helps compensate for nutrient and nitrogen...
HOW IT WORKS - This product helps keep yeast in suspension, helps keep volatile acidity levels low and helps absorb fatty acids that are toxic to yeast. Fermaid K contains a blend of inorganic nitrogen (DAP), organic nitrogen (alpha amino nitrogen...
HOW TO USE - Fermaid K nutrient works best if added in 2 doses. The first half of the dose is added 6-12 hours after pitching the yeast, and the other half once the sugar content is depleted by 1/3 of original gravity. Before adding the second dose, mix...
BREWING RECOMMENDATIONS - We recommend you use 1 gram per gallon of wine. For best results, this product should be used with a yeast rehydration nutrient to assure proper nutrition. The package contains 1 oz of Fermaid K.
CLARIFY YOUR BREWING - Try our Gelatin Finings to reduce haze and cloudiness when brewing beer and wine. When mixed with water, the finings are an effective clarifying agent, allowing you to brew clearer beers and wine. Gelatin Finings are to be used at...
HOW IT WORKS - Our Craft A Brew Gelatin Finings attract negatively charged particles (like yeast and protein), causing them to clump together and settle out of suspension. Gelatin Finings can also help remove tannin which reduces astringency (bitter or...
HOW TO USE - Once fermentation is complete, dissolve finings in water (2 oz water per gram of finings). Let rest and rehydrate for 15-30 minutes, then stir until there are no solids. Heat the mixture to at least 160℉ to dissolve finings. Next, let the...
BREWING RECOMMENDATIONS - We recommend you use 1 gram per gallon. Our Craft A Brew Gelatin Finings package contains 1 oz. This product can be used in combination with other clarifiers or fining agents added earlier in the home brewing process.

How to Choose the Best Beer Brewing Additives
Usage and Dosage
Each additive will have specific instructions regarding when and how much to use. Over-addition can sometimes lead to undesirable results or off-flavors, so it's essential to follow recommended dosages. Start with smaller amounts if you're experimenting, and keep notes on the impact of any additive you use. Understanding the science behind each additive will help you make informed decisions about its application in your brewing.
Frequently Asked Questions
What is the purpose of yeast nutrient?
Yeast nutrient provides essential vitamins, minerals, and amino acids that yeast needs to thrive during fermentation. This leads to a healthier fermentation, reduces the risk of stalled ferments, and can help prevent off-flavors from developing.
How do fining agents work to clarify beer?
Fining agents work by attracting and binding to suspended particles in the beer, such as yeast or proteins. This causes them to clump together and settle to the bottom of the fermenter or conditioning vessel, resulting in a clearer final product.
Can I use brewing additives in any beer style?
While many additives are versatile, some are best suited for specific beer styles. For example, certain enzymes might be used in low-carbohydrate beers, while others are standard for achieving clarity in lagers. Always consider the desired outcome for your chosen style.
How much fining agent should I use?
The amount of fining agent to use varies by product and batch size. It's crucial to follow the manufacturer's recommended dosage, typically measured in grams or as a single tablet per batch. Overusing fining agents can sometimes lead to unintended effects.
Are brewing additives necessary for beginners?
Brewing additives are not strictly necessary for beginners, but they can be very helpful. Yeast nutrients, for instance, can significantly improve fermentation reliability, making the brewing process more forgiving. As you gain experience, you can explore other additives to refine your beer.
