Untitled Art Peanut Butter Jelly Imperial Stout is an Imperial Stout by style. Imperial Stout brewed with REAL peanut butter, like a lot of real peanut butter then a blend of strawberry, raspberry, and black current purées to get the jam-like flavor just right, then a little bit of milk sugar for extra sweetness. This craft beer is 11% ABV. In this review, we will take a look at the color, smell, and taste.
