ABV: 10.2%
Aggressive but refined, our Narwhal is a malty monster of a beer.
Like the sea herself, it canāt be tamed; 10.2% ABV commands reverence.
Boasting a velvety smooth body and a decadent finish, Narwhal is rich with notes of espresso, bakerās cocoa, roasted grain, and a hint of smoke.
Dive into the darkness.
