Well, if we’re going to keep having heat waves in November, we may as well break out the leis and tropical shirts! Blue Owl Brewing celebrates 10 years as Austin’s center for sour ales. During that decade, one of their signature brewing techniques has been to mix souring with South Pacific fruity flavors, like milkshake sour IPA’s Lime in the Coconut and Tiki Hop Totem, so the whole day will be dedicated to that island life. With vendors, a limbo contest, and exclusive merch & glassware, it’s the only way to beat this heat, and there’s even a special gift for anyone who wears suitably tropical attire. Best of all, each Blue Owl brewer has created their own super-secret sour for the day, and they’ll all go head-to-head (or glass-to-glass) in the Tropical Drinksplosion: First keg to run dry wins! – Richard Whittaker
