Flying Dog is releasing “Brewhouse Rarities” each month in 2012. The beers will be limited to draft only, and the Mid-Atlantic region. The first release was Imperial Hefeweizen. Other potential releases include Black Lager, and Disobedience Dubbel (to also see bottles) and Berliner Weisse. Some of the batch of Berliner Weisse was going to be aged with sour cherries for a little before/after touch.
note: The above is tentative. Subject to change at whim of the brewer, the beer, or the barrel.
