Brew exceptionally smooth, clean lagers with White Labs WLP940 Mexican Lager Yeast | PurePitch® Next Generation, a premium liquid lager yeast originating from Mexico City and developed for producing crisp, refreshing beers with balanced malt character and restrained ester production. Each 70 mL PurePitch® Next Generation pouch contains approximately 150 billion cells, providing enough healthy yeast to ferment a standard 5-gallon batch without requiring a starter for most moderate-gravity lagers. WLP940 is an excellent choice for brewers crafting authentic Mexican Lagers, Vienna Lagers, Helles, Märzen, Pilsners, and American Lagers with exceptional clarity, smoothness, and drinkability.
WLP940 is known for creating a remarkably clean fermentation profile that allows subtle malt sweetness and delicate hop character to shine without producing heavy esters or distracting fermentation flavors. Its medium flocculation supports excellent clarification after lagering, while its balanced attenuation produces crisp, refreshing beers with a smooth finish. This strain performs particularly well in light-colored lager styles where fermentation cleanliness and drinkability are essential.
This liquid lager yeast features medium flocculation, 70–78% attenuation, STA1 negative status, and an alcohol tolerance of 5–10% ABV. It performs best between 50–55°F (10–13°C) and is packaged in White Labs' PurePitch® Next Generation pouch, which contains approximately 150 billion cells for improved pitching rates and fermentation consistency. The strain is intended for brewers seeking authentic Mexican-style and continental lager character with dependable fermentation performance.
For best results, store refrigerated between 33–38°F and do not freeze. Pitch cold into well-oxygenated wort and maintain fermentation temperatures between 50–55°F. While most standard-strength lagers can be fermented directly from one pouch, a yeast starter is recommended for higher-gravity beers or older yeast. Proper oxygenation and healthy fermentation practices will help maximize attenuation, clarity, and overall fermentation performance.
Produced to White Labs' professional fermentation standards, WLP940 Mexican Lager Yeast | PurePitch® Next Generation is widely used by homebrewers and professional brewers seeking reliable, authentic lager fermentation. Its clean profile, healthy cell count, and consistent performance make it an outstanding choice for brewing crisp, refreshing lager styles with excellent balance and clarity.
