While sour beers have become more popular over the years, for many they represent uncharted or little-understood territory. In this edition of 91X‘s weekly staple segment, Beer for Breakfast, the crew dives deep into the world of barrel-aged sour beers with a pair from “San Diego’s sour house”, California Wild Ales. That pair of tarts includes Diabolical Saison, a farmhouse ale brewed with ancient-grain spelt, and an autumnal-geared pastry sour marrying fuyu persimmons and cinnamon spice called PerCinnamon. Take a listen to get the crew’s impressions of these barrel-aged standouts plus a crash course on what makes sour beers sour.
