On tap at Julian’s, mild (despite wild tag) sour ale collaboration (with nearby Colorado brewery, Avery) brings subtle brettanomyces acidity and light horse-blanketed barnyard leathering to herbal-tinged tropical fruiting. Honey-dipped grapefruit, orange, mango, tangerine, peach, pineapple and mango illusions drift in and out of musty palate. Sessionable sour ale suffices.
