Active Dry Lager Brewing Yeast

ART-BW-015 is an active dry lager brewing yeast formulated for bottom fermentation at controlled cellar temperatures. Typical technical targets include viable cell count of not less than 5×10^9 CFU/g at packing, moisture not more than 8.0%, medium to high flocculation, and apparent attenuation commonly in the 78–84% range, depending on wort composition, oxygenation, pitch rate, and fermentation temperature. The yeast is intended for cold-fermented beer production where brewers require a clean malt-forward profile with restrained fruit notes and manageable sulfur behavior during maturation.

The product is packed in a 10 kg oxygen- and moisture-barrier foil pouch for commercial handling. It can be rehydrated before pitching or direct-pitched according to brewery SOP, with validation recommended at production scale. Suggested fermentation range is typically 10–15°C for primary lager fermentation, with a diacetyl rest applied as required by recipe and tank profile. Procurement teams can request a bulk quote on request for ART-BW-015, including wholesale pricing on request, lead time, palletization, and export documentation.

• Pilsner and helles brewing: supports crisp, clean fermentation where bitterness, malt quality, and water chemistry should remain clear in the finished beer.
• Marzen, Vienna lager, and amber lager: suitable for malt-accented recipes requiring dependable attenuation without excessive ester contribution.
• Craft brewing scale-up: 10 kg pouches allow brewers to standardize pitch rates across brewhouse sizes, pilot-to-production transfers, and multi-site operations.
• Contract and private-label brewing: useful where batch repeatability, documented lot traceability, and predictable fermentation kinetics are required for customer specifications.
• Beverage R&D and process trials: appropriate for recipe screening, fermentation temperature mapping, and comparison against house yeast performance under controlled wort conditions.

Store unopened pouches in a cool, dry area away from direct sunlight, strong odors, and condensation. Recommended storage is 4–10°C for best viability retention; short ambient transport exposure may be acceptable when validated through receiving inspection. Typical shelf life is up to 24 months from manufacture when the pouch remains sealed and stored under recommended conditions. Once opened, use promptly, reseal under sanitary conditions if partial use is unavoidable, and avoid repeated warm-up cycles.

For rehydration, use sterile or hygienically treated brewing water in the approximate range of 25–30°C unless a brewery-approved procedure specifies otherwise. Avoid direct contact with high-gravity wort during the first minutes of rehydration, as osmotic stress can reduce vitality. Confirm pitch rate based on original gravity, target fermentation temperature, desired fermentation time, and tank geometry.

ArtemisYeast supplies ART-BW-015 for professional brewing use with lot-level traceability and specification review before shipment. A certificate of analysis may include appearance, moisture, microbiological indicators, viable cell count, and lot identification. Manufacturing is managed under food-safety and quality systems aligned with HACCP principles; documentation for ISO 22000, FSSC 22000, Halal, Kosher, allergen status, non-GMO statement, and food-grade declaration may be available on request where applicable to the production lot.

Incoming quality teams should verify pouch integrity, lot number, storage condition, and CoA conformity before release to production. ArtemisYeast can support procurement dossiers, supplier questionnaires, and export paperwork for international brewery buyers.
