I just tapped the keg this afternoon, and I'm really liking it.
It has a light and bright citrus flavor that kind of reminds me of Five Alive (maybe tangerine with some lemon/lime?). There's also something else going on that I can't really put my finger on, maybe a slight earthiness, but that could be from the Columbus. They seem to pair together pretty well.
I'll probably re-brew this one again sometime.
