Technical Data Sheet

Yeast management, instructions for use, recommended pitch rates, specifications, and more.

No Equivalent.

Nearly four decades of expertise in crafting yeast for cidermakers around the world shows that there’s more to a strain than its name and number. Wyeast yeast is unparalleled in quality and performance, guaranteed.

  • Purity

    A rigorous quality control and quality assurance program utilizes both traditional methods and modern innovations to guarantee culture purity and single morphology down to the threshold of detection. Cultures, ingredients, and equipment are analyzed and held to strict specifications throughout the entire propagation process. Complete QA/QC analysis on every finished product means our strict specifications are always met before your order ships.

    Analyses include:

    • Plating on general and selective media for detection of viable yeast and bacteria contaminants
    • Colony morphology on differential agar
    • Cell morphology with phase contrast microscope
    • qPCR confirmation of commercial yeast species (S. cerevisiae,  Brettanomyces, and more)
    • qPCR screening for the detection of cellar contaminants

  • Precision Cell Density

    Wyeast provides the most precisely packaged yeast slurry to guarantee consistent, reliable fermentations in your cidery. No range or minimum – we prepare our products at exactly 1.2 billion viable cells per milliliter with advanced cellometer & validation processes. This results in > 99.9% viability for your target pitch rate – delivering the most accurate cells per mL per Plato calculations for reproducible fermentations.

  • Customizable Packaging & Pitch Rates

    With over 35 years of experience in the fermentation industry, our liquid yeast is proven to offer the ideal balance for successful fermentations without over-or-under pitching. Custom packaging options and a low minimum volume on every strain means all cideries and fermentation sizes can be accommodated.

  • Optimal Propagation Conditions

    Every strain is initiated from our ultra-low temperature archive in order to maintain genomic stability, ensuring the culture maintains consistent fermentation kinetics, flavor profiles, and flocculation characteristics.

    Cultures are propagated using a premium nutrient-rich medium under optimal aeration and temperature parameters for growth and cell health.

  • Fresh without Compromise

    Wyeast ships directly from our facility to yours, guaranteeing the freshness and integrity of every order. One production facility means consistency and reliability, batch after batch.
