Avery Immitis Barrel-Aged Sour Ale

As part of a beer trade with Lee from Hoptopia, I received a bottle of Avery Immitis Barrel-Aged Sour Ale. The beer pours a dark brown color with a bubbly tan head that receded rapidly. The aroma consists of vinegar, chocolate, cherry, and toasted malts. The taste is extremely puckering with sour cherry, vinegar, grapes from the zinfandel barrels, and a hint of toasted malts. There is a bit of chocolate on the finish that barely pokes through due to the sourness, and a dry oaky after taste. The alcohol content is 9.87% ABV. I was extremely surprised as to how sour and puckering this beer was, but it was phenomenal. The sourness lingers with a tart cherry flavor for quite a while, and I loved the chocolaty background that this beer was built upon.
