Brewed in the classic Flemish Red style, Red Flag is brewed in small batches on our 15 Barrel Brewhouse. Each batch is aged in stainless and then moved to bourbon and red wine barrels for further maturing. The barrels are then hand selected and blended to create the most complex and seductive sour ale possible. Red Flag is the first sour offering in the Uncharted Waters series. Deep ruby in color, this barrel aged sour ale delights with sweet malt tones, complex fruit undertones, and a deliciously tart finish.
