Whiskey and Bourbon Distillation Yeast

ART-BW-034 is a dry distillers yeast for bourbon, rye, malt whiskey, corn whiskey, and craft grain-spirit workflows. It is intended for fermentation of cooked and converted cereal mashes where temperature control, attenuation, and flavor precursor development must be balanced at production scale. The strain profile is ester-forward, supporting fruity and grain-integrated congeners after distillation while maintaining reliable sugar uptake in high-solids mash systems.

Typical specification targets include viable yeast count of not less than 1.0×10^10 CFU/g at packing, moisture not more than 8.0%, and fine granular active dry yeast with low dusting for controlled dosing. Typical alcohol tolerance is up to 15-17% v/v under suitable nutrient, temperature, pH, and osmotic conditions. Recommended initial fermentation pH is generally 4.0-5.5, with operating temperatures commonly in the 30-38 degC range depending on mash bill and plant protocol.

• Bourbon and corn whiskey: Supports fermentation of corn-forward mash bills with controlled ester formation and dependable attenuation after starch conversion.
• Rye whiskey: Suitable for viscous cereal mashes where active dry yeast handling, fast dispersion, and warm-temperature robustness are required.
• Malt whiskey and scotch-style workflows: Applicable to malt wort and mixed-grain distillation streams where a clean grain base with fruit ester lift is desired.
• Craft and industrial distilleries: Designed for batch tanks, continuous preparation systems, pilot plants, and contract production where yeast performance must be documented by lot.
• R&D and scale-up: Appropriate for bench trials, mash bill screening, and process validation before plant-level procurement. For new projects, submit target mash gravity, temperature profile, and package volume through request a quote.

Store unopened 10 kg foil pouches in a cool, dry, odor-free warehouse, ideally below 20 degC and away from direct sunlight, steam lines, acids, oxidizers, and strong aromatic materials. Under recommended storage, typical shelf life is 24 months from manufacture, subject to lot confirmation. After opening, reseal tightly or transfer to a clean, dry, food-contact container and use promptly to limit moisture uptake and viability loss.

For direct pitching, dose according to mash gravity, contamination risk, and desired fermentation time; common starting ranges for active dry distillers yeast are 0.3-1.0 g/L. Rehydration may be used where plant SOPs require it: use clean water at 35-38 degC, avoid chlorinated water, and introduce yeast gradually to reduce osmotic shock. Do not mix dry yeast directly with caustic cleaners, high-proof alcohol, or undiluted acids.

ArtemisYeast supplies ART-BW-034 for B2B beverage and distillation customers that require traceable lots and procurement-ready documentation. Standard documentation available on request may include certificate of analysis, product specification, safety data sheet where applicable, allergen statement, non-GMO statement when available by lot, and food-grade declaration. Manufacturing and supplier review materials may reference HACCP-aligned controls, ISO 22000, FSSC 22000, Halal, or Kosher documentation where available for the production site and shipment lot.

Each bulk inquiry can be reviewed for target viability, moisture, microbiological limits, packaging, palletization, and export paperwork. Visit quality and documentation for the type of records procurement, QA, and plant teams commonly request before vendor approval. Wholesale pricing on request is provided after destination, annual volume, delivery terms, and document requirements are confirmed.
