The Blue Mule is a sour ale inspired by an off-centered twist on the classic Moscow mule cocktail. Brewed with pureed blueberries, ginger juice, lime juice, lime zest, kaffir lime leaf and lactose, and aged on a touch of fresh rosemary, it has all the flavors you would expect - the fresh berry fruitiness, the heat of the ginger, the quenching bite of lime and the subtle herbal, pine notes of rosemary - all layered together in a balanced sweet and sour base beer. It may not come in a copper mug, but we did all the fancy mixology for you!
