White Labs | WLP810 San Francisco Lager Yeast | PurePitch® Next Generation

Brew authentic California Common and hybrid lager styles with White Labs WLP810 San Francisco Lager Yeast | PurePitch® Next Generation, a unique liquid lager yeast that ferments cleanly at warmer ale temperatures while retaining classic lager-like character. Each 70 mL PurePitch® Next Generation pouch contains approximately 150 billion cells, providing enough healthy yeast for a standard 5-gallon batch without requiring a starter for most moderate-gravity beers. WLP810 is the traditional choice for California Common (Steam Beer) and is also well suited for Cream Ale, Amber Lager, American Lager, Märzen, Pale Lager, and Kölsch-style beers.

Unlike most lager strains, WLP810 performs best between 58–65°F (14–18°C), making it an excellent option for brewers seeking crisp, lager-like beers without dedicated cold fermentation equipment. It produces a clean fermentation profile with restrained ester character while allowing balanced malt and hop flavors to shine. Lower fermentation temperatures create a cleaner lager profile, while the upper end of the range adds subtle complexity without sacrificing drinkability.

This liquid lager yeast features high flocculation, 70–75% attenuation, STA1 negative status, and medium alcohol tolerance (5–10% ABV). White Labs' PurePitch® Next Generation pouch delivers approximately 150 billion cells for reliable fermentation performance and consistent pitching rates across a wide range of hybrid and lager beer styles.

For best results, store refrigerated between 33–38°F and do not freeze. Pitch cold into well-oxygenated wort and ferment within the recommended temperature range. While one pouch is suitable for most standard-strength 5-gallon batches, a yeast starter is recommended for higher-gravity beers or older yeast to ensure optimal cell health and fermentation performance.
