A little over a year ago, some friends introduced me to "sour" ales. This is definitely something that can take a little getting used to. The first I had was Monk's Cafe and it is quite good. I haven't really tried to find any new ones lately, but got a little urge to try a few. One was a natural disaster and one of the nastiest brews I've ever tried, however this one was very nice.
The color was a dark brown, but very clear. It had a clean aroma with a bit of yeast, but not very strong. Now, for the flavor. If you've not had a sour beer, they are completely different. There is a slight sourness, but I equate it more like a slight vinegar sour (but not taste). The flavor of this particular beer is very slightly of cherry and caramel malt. The sour provides a crispness to the beer and it is very clean with little after-taste. It has a lot of carbonation and is quite "fizzy," though the head is very small and not thick at all. This will make a great summer beer on a warm day (which it happened to be today).
