Otter Creek 20th Anniversary Ale

I have only had a couple beers from Otter Creek before, but the 20th Anniversary Ale has me hooked on the brewery.  The lable says that its just an ale, but from my opinion it ia  Barley Wine.  While Barley Wines tend to have a wine flavor, 20th has a mild chocolate flavor, much like Orkney's Skull Splitter.  I saw this beer in the store today and I grabbed in just because it was limited edition, and I am very impressed. I like barley wine's but it is not my favorite variety of beer.
