From Fermentis' Site "Robust ale yeast able to tolerate high alcohol conditions (up to 11.5% v/v). Used to produce a wide range of beer styles including Belgian wheat and Trappist beers" In our experience, this yeast works well as an all-purpose ale yeast, fermenting clean in cooler temperatures without excess fruity esters. Tends to not flocculate as well as the S-04 or US-05, which may or may not be an issue to the homebrewer bottling their beer, depending on style. At this price, keep a few packs on hand!
