Imperial Stout w/ Chocolate and Peanut Butter Here's a not so hot take - ice cream is fantastic. So, we decided to take one of the most elite ice cream flavours and jam it in a stout. Bullwinkle is rich, sweet, and loaded with fudgy chocolate and rich ooey gooey peanut butter. It drinks like a bowl of melted ice cream, and tastes like it too!
