Westbrook Brewing Co. is about to turn nine years old and is celebrating the best way a brewery knows how: by releasing yet another special beer to mark the occasion.

According to a label filed with the Alcohol and Tobacco Tax and Trade Bureau (TTB), this ninth anniversary beer will be a 10 percent ABV stout brewed with peanut butter, cocoa nibs and vanilla.

Previous anniversary beer iterations have included a pecan cookie stout and a hazelnut and chocolate stout, amongst others.

An email sent to the brewery was not immediately returned.
