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.
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.

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.
