I'll drink and enjoy anything the folks at Stone brew. That's just a fact.
On the other hand, whatever BrewDog puts in a bottle promises an awful lot, but it rarely delivers on that promise.
This beer somehow fulfills both prophesies. Like the black pilsner they collaborated on, the beer defies style and definition. It's black black with lovely lacing. The aroma is big, roasty, raisiny, and even oddly hoppy. However, the mouthfeel is a bit watery and the flavor doesn't quite live up to what's promised in the appearance and smell.
That said, I enjoyed the beer anyway. It's still better than 90% of the beers out there and is unique enough of an experience to warrant another pint.
