Black Star Co-op's Waterloo

It's summer. Have you noticed? No? Well, wake up, it's been over 100 degrees for the past 30something days (or something like that). Summer beers are made for this is the weather. Black Star's new irrational beer is called Waterloo, a “sour peach wheat ale.” It was brewed for the summer and most likely you've had it already. But if you have not (or even if you have), Jeff Young recently posted about the birth of the beer:

We thought about what that could be…light, tart, easy-to-drink with subtle flavor and elegance. From there, I wanted to experiment with souring beers and using peaches as the subtle yet complex flavor.

Jeff also explains the process of sour mashing. Interesting read.
