Our most popular strain is WLP001-California Ale yeast. This blend celebrates the strengths of California - clean, neutral fermentation, versatile usage and adds two other strains that belong in the same" clean/neutral" flavor category. Homebrewers have speculated that it may be a blend of the WLP001, WLP051 Cal IV, and WLP810 San Francisco Lager but this blend has never been proven. The additional strains create complexity to the finished beer, and will taste more lager like than just WLP001. Hop flavors and bitterness are accentuated, but not to the extreme of WLP001 by itself. Slight sulfur will be produced during fermentation.Attenuation: 72-80% Flocculation: Medium Optimum Fermentation Temp: 68-73Wyeast Equivalent: NoneFor best results we always recommend ordering an ice pack with your liquid yeast.
