Karl Strauss and San Diego go together like peanut butter and chocolate. That's why we chose San Diego Beer Week back in 2012 as the perfect place to debut our Peanut Butter Cup Porter. This decadent twist on a robust porter packs rich layers of smooth peanut butter and dark chocolate flavors. Now back by popular demand, San Diego's original peanut butter beer makes a special appearance every fall. It turns out you really can have your dessert… and drink it too.
