Dry Homebrew Yeast Coming Soon

White Labs wouldn’t be here without our first yeast strain produced in 1995, WLP001 California Ale Yeast®. This strain is a favorite in our collection and is used in some of the best beers around the world. This product comes in a Liquid Yeast and a Dry Yeast. 

WLP001 is famous for its clean flavors and hardy fermentations and is known for its use in hoppy beers. It accentuates hop flavors and aromas and attenuates well, even for high-gravity beers. A higher-than-average attenuation leads to drier beers as well as medium flocculation to leave a clean and crisp beer. With a healthy pitch and yeast, WLP001 is also quick at reabsorbing diacetyl. 

  • Best-selling yeast
  • Can be used in almost any style of ale (from IPA to kölsch)
  • Beautifully accentuates hop flavors and aromas
