This strain was the first yeast strain produced by White Labs in 1995. It’s their best-selling yeast, famous for its clean flavors and hardy fermentations. Known for its use in hoppy beers, it accentuates hop flavors and aromas and attenuates well, even for high gravity beers. 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.

In blind testing, Marshall Shott found that 15 of 23 tasters could tell the difference between otherwise identical ales brewed with WLP001 and US-05.  When asked which beer they preferred the group was evenly split.  It was clear that there IS a difference, but some prefer US-05 and some prefer WLP001.  You’ll just have to try it for yourself…
