So this was (believe it or not) my first ever chocolate stout, so keep in mind that my frame of reference is non-existent.
When they say chocolate stout, they mean CHOCOLATE STOUT. Very stouty, very chocolaty. Very strong as well (11% ABV). As you would expect with a stout, the beer is quite heavy, and a bit bitter at first. I ended up milking the pint for close to an hour.
All in all, it was a decent beer. I wouldn’t ever drink more than one in a sitting.
