My first impression was that this was a bit too sour - but as I went, the sweetness and the sourness kind of balanced out. And it was a pleasant sour. In the end, surprisingly good.
It certainly tastes like black currant, which is nice and unusual, but like most of these New Glarus fruit beers, is way more juice than beer. I usually have a hard time drinking intensely fruity berry juices, and this had more or less the same effect on me.
