Built by two longtime friends and brewers from the Pittsburgh area, Abjuration Brewing is a local nano brewery making small-batch American ales with a particular fondness for hoppy and sour styles. Its “versioning” approach treats every recipe tweak as a new iteration, while a mad-scientist outlook keeps the brewery experimenting with new ingredients and releasing something different rather than maintaining fixed flagship beers. The brewery also tries to source ingredients locally when possible for its Pittsburgh neighbors.
