Rhythm and Blues. Batman and Robin. Peanut Butter and Chocolate. These classic duos never go out of style. Enter Peanut Butter Milk Stout. Left Hand Brewing took the pure milk chocolate bliss of the classic Milk Stout and added peanut buttery goodness. It’s like an adult peanut butter cup you can drink. It’s rich and decadent on the palate and lusciously lingers into a nutty, dry finish.
