Rich milk chocolate notes team up with peanut buttery perfection for a deliciously dark duo. Rhythm and Blues. Batman and Robin. Peanut Butter and Chocolate. These classic duos never go out of style. Enter Peanut Butter Milk Stout. We took the pure milk chocolate bliss of our 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. A perfect pair you'll want to share.
