Smells like a beet salad - vinegary, earthy, very, very recognizable as beet. Flavor is somewhat less beety, but quite tart. Beet again on the aftertaste. This beer at once gets easier and harder to take as you drink more. I think this may be #3? #2? on my list of beet beers. I can't believe I just typed that.
So much carbonation, to the point of being a bit painful on the lips. Behind it is a sweetish lactic creaminess on a slightly sour stout. The experience was pretty masked by the carbonation though.
