Distillation Yeast for Neutral Spirit

ART-BW-032 is a high-alcohol-tolerance distillation yeast formulated for neutral spirit production. The strain is designed to ferment efficiently in well-prepared mashes up to approximately 17% ABV under appropriate nutrient, temperature, pH, and solids-control conditions. It is suitable for producers targeting a clean base alcohol for vodka, gin, liqueur alcohol, rectified spirit, and neutral grain spirit, where fermentation reliability and low sensory carryover are procurement priorities.

Typical specification targets include active dry yeast format, moisture not more than 8%, viable count commonly not less than 1.0×10^10 CFU/g at packing, and tan to light-brown granules with characteristic yeast odor. Recommended fermentation conditions are generally 28-34°C, pH 4.0-5.5, and a pitch rate of 0.3-0.8 g/L depending on gravity, substrate, and process risk. For adjacent strains and formats, review the brewing and winemaking yeast category.

• Neutral grain spirit: Fermentation of wheat, corn, rice, barley, sorghum, or mixed cereal mashes after liquefaction and saccharification, supporting clean ethanol production for rectification.
• Vodka alcohol base: Use where the process objective is high attenuation with minimal ester or higher-alcohol contribution before distillation and polishing.
• Gin base spirit: Production of neutral alcohol intended for later botanical redistillation, vapor infusion, or compounding according to the distiller’s process design.
• Sugar and molasses wash: Applicable where a controlled nutrient program is used to avoid sluggish fermentation and maintain yeast vitality through high-gravity operation.
• Continuous or batch distilleries: Compatible with standard dry yeast rehydration, direct pitching where validated, and scale-up trials from pilot fermenters to production tanks. Request a bulk quote on request with target substrate, annual volume, and packaging preference.

Store unopened 10 kg foil pouches in a cool, dry, odor-free warehouse, ideally below 25°C and away from direct sunlight, steam lines, oxidizing materials, and high humidity. Under recommended storage conditions, typical shelf life is 24 months from manufacture, subject to lot confirmation on the certificate of analysis. Once opened, reseal tightly or transfer to a clean, dry, food-grade container and use promptly to limit moisture uptake and viability loss.

For rehydration, disperse the yeast into clean water at 35-38°C at approximately 5-10 times its weight, hold for 15-25 minutes, then acclimate gradually with mash to reduce thermal and osmotic shock. Do not mix dry yeast directly with concentrated sanitizers, acids, or undiluted nutrients.

ArtemisYeast supplies ART-BW-032 for B2B distilling operations under lot-controlled procurement procedures. Standard documentation can include certificate of analysis, specification sheet, allergen statement, GMO-position statement where applicable, food-grade declaration, safety data sheet, and country-of-origin or export documents as required for the shipment. Manufacturing and release controls are HACCP-aligned, and documentation related to ISO 22000, FSSC 22000, Halal, or Kosher status may be provided where applicable to the producing site and lot.

Microbiological and physicochemical parameters are monitored to support consistent performance, including moisture, appearance, viable yeast count, and indicator organisms according to the agreed specification. For supplier approval, audit questionnaires, sample requests, and technical review can be coordinated through our quality documentation process. Wholesale pricing on request is available for distilleries, ingredient distributors, and contract alcohol producers.
