According to the Baltimore Sun, here. No real quibbles with this list, even if Stillwater's Of Love & Regret is one of my least favorite so far (I'm willing to concede I had a bad bottle or that my palate just isn't ready for it). Actually, without thinking too much on any glaring omissions, I think this list provides a good overview of the best of the Maryland craft scene, and most are readily available in the area from a decent craft beer store.
Of this list, which would I rank number one? Evolution Lot No. 3 IPA.
A cool experience is having a Heavy Seas Loose Cannon, number two on their list and mine as well, at a baseball game at Oriole Park at Camden Yards. Hopefully, it and another winning Orioles team reappear at the ballpark in 2013.
