On tap at Amazing Grapes, saison-styled sour ale blends French and American oak-barrel aged Opal Saison, thrusting lactic brettanomyces acidity upon lightly vinous lemon-seeded green grape tartness and rustic barnyard-grained musk. Delicate Sauvignon Blanc, unripe peach and apricot wisps dissipate beneath lemony white wine tannins.
