On tap at Copper Mine, softly vinous sour ale loads pureed green apple tartness atop sulfuric compost-wafted wasabi root adjunct and acrid lemon-limed green grape pucker with limited success. Heavy lactic acidity and musty barnyard funk saddle sharp dry-hopped citric-quince tartness. At the sour-fruited finish, harsh horseradish-like wasabi influence dissipates a tad.
