These are also known as “soured beers” and their defining character classically comes from having been aged for some years in well-used, large wooden tuns, to allow bacterial action in the beer and thus impart the sharp “sour” character. Hops do not play much role in the flavor profile of these beers, but whole cherries can be macerated with the young beer to produce a cherry-flavored Belgian red ale. These styles are almost exclusively linked to one producer in northern Belgium, Rodenbach. These ales are among the most distinctive and refreshing to be found anywhere.
