Brewing Yeast Nutrients and Protectors

ART-BW-032 is a dry nutrient and protector preparation for fermentation workflows where yeast requires an available supply of amino nitrogen, growth factors, mineral cofactors, and cell-wall-derived protection materials. It is intended as a process aid for fermentation management, not as a primary pitching yeast. The matrix may include inactivated yeast derivatives, autolyzed yeast solids, yeast extract fractions, mineral nutrients, and cell wall components selected for dispersion and process compatibility.

Typical specification targets include light tan to beige powder or fine granules, moisture not more than 8.0%, crude protein commonly 35% or higher, total nitrogen typically 5.0% or higher, ash commonly not more than 12.0%, and particle size with not less than 95% passing 40 mesh, subject to final product confirmation by lot. Brewers use this type of material to improve nutrient balance in high-gravity wort, adjunct-rich recipes, repitched yeast programs, and fermentations where free amino nitrogen or micronutrient levels may be limiting. Related products are listed in our brewing and winemaking yeast category.

• Craft brewing: Addition to wort or fermentation vessels for ales, lagers, high-gravity beers, adjunct beers, and specialty fermentations where nutrient consistency is required across batches.
• Yeast rehydration and protection: Use in validated rehydration or pre-pitch routines to help reduce osmotic and ethanol stress during start-up, especially for dry yeast handling programs.
• Winemaking and cider: Suitable for technical review in grape, fruit, and cider fermentations where must composition varies and controlled nutrient scheduling is preferred.
• Distilling fermentations: Applicable to grain, sugar, and mixed-substrate mashes where operators require stable attenuation and repeatable fermentation kinetics.
• Industrial fermentation: May be evaluated as a dry fermentation support ingredient for non-beverage processes that require food-grade or feed-grade documentation, depending on the selected lot and regulatory destination.
• Procurement planning: Supplied as ART-BW-032 in 10 kg foil pouches for pilot trials, plant qualification, and palletized supply. Submit target use rate, destination country, and annual volume through bulk quote on request.

Store unopened 10 kg foil pouches in a dry, cool, and well-ventilated warehouse, typically below 25°C, away from direct sunlight, steam lines, strong odors, and sources of condensation. Keep packaging sealed until use and reseal partly used pouches promptly to limit moisture uptake. Under recommended storage conditions, typical shelf life is 18 to 24 months from manufacture, subject to the exact formulation, packaging date, and lot certificate.

Use clean, dry scoops and closed transfer practices to reduce environmental contamination and dust generation. Recommended addition points and dosage should be confirmed by trial because wort gravity, yeast strain, temperature program, oxygenation, and raw material composition all affect nutrient demand. Common evaluation ranges are 10 to 40 g/hL for fermentation nutrient supplementation and 20 to 60 g/hL in rehydration or protection steps, adjusted according to house process validation.

ArtemisYeast supplies ART-BW-032 for B2B qualification with lot-specific documentation available on request, including certificate of analysis, specification sheet, safety data sheet where applicable, allergen statement, GMO status statement, country-of-origin information, and food-grade declaration. HACCP-aligned manufacturing records and documentation for ISO 22000, FSSC 22000, Halal, or Kosher status may be available depending on the producing site and lot; buyers should confirm required documents before purchase order release.

Quality review can include moisture, appearance, odor, particle size, total plate count, yeast and mold, coliforms, and pathogen screening as specified for the intended market. For export programs, ArtemisYeast can coordinate carton marks, pallet configuration, batch traceability, and document packs through our quality documentation process.
