Excelsior Bitteschlappe Brown Ale

This 6.5% ABV beer is from the Excelsior Brewing Company of Excelsior, Minnesota. Excelsior is on the shores of Lake Minnetonka, and you'll see a lake activity theme on the bottles of their beer. 

The beer pours a dark chestnut brown. There is an inch of creamy head, very light tan in color. The aroma is nutty, malty, some caramel, with a tang of dark stone fruits. The flavor unfortunately is sour, vinegar with a touch of soap and vomit. This beer is infected. I got five bottles of Excelsior beer on a trip to Minnesota and two of the four I have tried were infected. It’s too bad, as the uninfected beers were really nice.  Their bottling process needs some quality control attention.
