The production story here is the interesting bit. Guinness 0.0 goes through the full brewing process before cold filtration strips the alcohol out, which means the roast character, creaminess and dark chocolate notes survive the process reasonably intact. Pop the can and you get the familiar cascade; the head builds properly and sits thick on top. On the palate, the roasted barley comes through clearly, with coffee and a touch of chocolate in the background. It's not as rich as the original, and the body is lighter than you'd expect if you didn't know it was 0.0%, but the bitter finish lands cleanly. At 17 calories per 100ml it's one of the lighter stouts in the category. If you drink Guinness regularly and want a break from alcohol, this is as close as the format currently gets.
