BSY-A062
Leuven
Belgian (S. cerevisiae)
Leuven is a fascinating Belgian strain originally sold as Brettanomyces but reclassified as Saccharomyces cerevisiae. It produces intense tropical aromas of mango, pineapple, and stone fruit with a subtly tart finish, making it outstanding for American pale ales and hazy IPAs where big fruit character is desired. Extremely high attenuation (85%+) creates a very dry, thin-bodied beer, so consider mashing higher or adding unfermentable sugars for body. Very low flocculation maintains persistent haze. Ferment warm (21-27C) for maximum tropical ester production.
