BJCP 2021 Style 16D Foreign Extra Stout

This beer is on the sweeter end of things, which is how I like my stouts. According to the BJCP it's not bitter enough, which is mainly because it was originally intended to be a tropical stout! With a fruitier yeast and a few less IBU I think it would be a pretty good tropical stout.

This beer also got a 2nd place by adding chocolate extract at bottling time. I tried a couple of extracts dosed into a stout and the Uncle Roys extract tasted good.
