Good for Kölsch, Alt, and German style Pale Ales. Strong sulfur component will reduce with aging. Clean, but with more ester production than WLP029.
This is the yeast from one of the oldest stout producing breweries in the world. It produces a slight hint of diacetyl, balanced by a light fruitiness and slight dry crispness. Great for Irish ales, stouts, porters, browns, reds and a very interesting pale ale.
This yeast is a little more attenuative than WLP002. Like most English strains, this yeast produces malty beers. Excellent for all English style ales including bitter, pale ale, porter, and brown ale.

Clean, highly flocculent, and highly attenuative yeast. This yeast is similar to WLP002 in flavor profile, but is 10% more attenuative. This eliminates the residual sweetness, and makes the yeast well suited for high gravity ales. It is also reaches terminal gravity quickly. 80% attenuation will be reached even with 10% ABV beers.
Our "Brewer Patriot" strain can be used to reproduce many of the American versions of classic beer styles. Similar neutral character of WLP001, but less attenuation, less accentuation of hop bitterness, slightly less flocculation, and a little tartness. Very clean and low esters. Great yeast for golden, blonde, honey, pales and German alt style ales.
Produces a clean, malty beer. Pleasant ester character, can be described as "bready." Can ferment successfully, and clean, at higher temperatures. This yeast combines good flocculation with good attenuation.
Malty, Northern European-origin ale yeast. Low ester production, giving a clean profile. Little to no sulfur production. Low attenuation helps to contribute to the malty character. Good for Alt, Kolsch, malty English ales, and fruit beers.
Dry, malty ale yeast. Provides a complex, oakey ester character to your beer. Hop bitterness comes through well. This yeast is well suited for classic British pale ales, bitters, and stouts. Does not flocculate as much as WLP002 and WLP005.
Traditional mixed yeast culture. British style character, slightly fruity, with a hint of sulfur production. This yeast can be used for many different beer styles.

From a small brewpub in Cologne, Germany, this yeast works great in Kölsch and Alt style beers. Good for light beers like blond and honey. Accentuates hop flavors, similar to WLP001. The slight sulfur produced during fermentation will disappear with age and leave a super clean, lager like ale.
Traditional English style, single strain yeast. Produces signature ester character, and does not mask hop character. Leaves ale with a slightly sweet malt character. Best for bitters, milds, porters, and stouts. Also good for Scottish style ales.
This yeast produces a beer that is malty, but well-balanced. Expect flavors that are toasty with malt-driven esters. Highly flocculent and good choice for English pale ales, English brown ales, and mild ales.
Top-fermenting strain that is traditionally good for top-cropping. Moderately flocculent with a clean, dry finish. Low ester profile, producing a highly balanced English-style beer.
British style ale yeast with a very dry finish. Medium to low fruit and fusel alcohol production. Good top fermenting yeast strain, is well suited for top cropping (collecting). This yeast is well suited for pale ales, ambers, porters, and stouts.

From Northern California. This strain is more fruity than WLP001, and slightly more flocculent. Attenuation is lower, resulting in a fuller bodied beer than with WLP001.
Our most popular yeast strain is WLP001, California Ale Yeast.
