On tap at Ambulance Brew House, intricately designed moderate-bodied Swiss saison allows sour yellow fruiting to pick up gueuze-like lactobacillus acidity and brettanomyces funk. Lemon-pitted navel orange rot receives ultra-dry barnyard leathering and earthen mineral rusticity. Vinous white grape pucker enjoins bitter green apple and cranberry conflux at champagne-sparkled peppered citrus finish.
