Precision Cell Density
Wyeast provides the most precisely packaged yeast slurry to guarantee consistent, reliable fermentations in your meadery. 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 meaderies 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.
