Guiness Black Lager commercials came to the American airways a few months back and peaked my interest. I picked up a 6-pack of this roasted barley beer. It reminds me a more bold Shiner Black. This isn't as tasty as some of Guinness's fine beers but if you like darker beers that won't fill you up as quick as a regular Guinness will, try Guinness Black Lager.
How it was tasted: in a mug. Though I just read the "drink out of the bottle" text. D'uh!
