Barrel Tasting with Brewer Cory King at Side Project

Because they are so air tight, using a foeder when making sour beers keeps the oxygen levels low. The more oxygen, the more sour your beer. King is a brewer, but also a wine lover and looks for balance in his beers, much like a wine maker looks for balance in their wines. In fact, he incorporates Missouri-grown Chambourcin from Noboleis Vineyards into some fan-favorite sours.
