Brew clean, balanced American ales with White Labs WLP001 California Ale Yeast | PurePitch® Next Generation, White Labs' flagship liquid yeast strain trusted by homebrewers and professional breweries alike. Known for its neutral fermentation profile, dependable attenuation, and ability to showcase both hops and malt, WLP001 is one of the most versatile ale yeasts available. 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 beers. WLP001 is ideal for brewing American IPA, Pale Ale, Blonde Ale, Porter, Stout, Double IPA, and California Common styles.
WLP001 produces low ester levels and a clean, neutral fermentation profile that allows hop aroma, hop bitterness, and malt character to remain at the forefront of the finished beer. Its balanced performance and broad fermentation range make it equally suited for crisp hop-forward beers and malt-driven recipes. Medium flocculation promotes excellent clarity while delivering a dry, refreshing finish that has made this strain an industry standard for American craft brewing.
This liquid ale yeast features medium flocculation, 73–85% attenuation, STA1 negative status, and an alcohol tolerance of 5–10% ABV. It performs best between 64–73°F (18–23°C) and is packaged in White Labs' PurePitch® Next Generation pouch containing approximately 150 billion cells for reliable pitching rates and consistent fermentation performance.
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. One pouch is suitable for most standard-strength 5-gallon batches, while 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 beer quality.
Produced to White Labs' professional fermentation standards, WLP001 California Ale Yeast | PurePitch® Next Generation is widely recognized as the benchmark American ale strain for its clean fermentation, consistent performance, and exceptional versatility. Its healthy cell count, dependable attenuation, and neutral flavor profile make it an outstanding choice for brewing everything from hop-forward IPAs to balanced porters and stouts with professional-quality results.
