Maduro is a Northern English-style brown ale with some American affectations. Maduro is higher in alcohol than the common English brown ale and features flaked oats in the malt bill which imparts a silky body and works to mesh the roasted, toasted and chocolate components together in Maduro’s complex malt profile. The end result is a remarkably full-flavored yet approachable and sessionable brown ale.
