Mike and Kenneth return to the studio with Paul Vaughn, co-founder of Bearded Iris Brewing in Nashville. They discuss the intersection of bitter and sweet and how it plays out in creating tasty beverages. Over several pitchers, Paul discusses why a pitcher of beer was so important in the creation of Bearded Iris. They also deep dive on black lagers and the beginnings of Coca-Cola, hops, and using oyster shells in brewing. In a wide-ranging booze news, Kenneth discusses pedal taverns in Nashville, underground tunnels used by the Queen and Mariah Carey’s “Black Irish” name dispute.
