WLP001 California Ale Yeast®
White Labs wouldn’t be here without our first yeast strain produced in San Diego in 1995, WLP001 California Ale Yeast®. This strain is a favorite in our collection and is used in some of the world’s finest beers.
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 of yeast, WLP001 is also quick at reabsorbing diacetyl.
This strain has the ability to be used in almost any style of ale ranging from IPA to porter and even kölsch, which makes it a great all-around house strain. Now in liquid and dry format.
