Frederick's technically part of the DC/Baltimore metro areas, but the historic little hamlet couldn't be further from the chaotic metropolitan bluster, with its covered bridges, 18th-century architecture, and general timelessness. Oh, and they've got beer. Lots and lots of beer, proving that Maryland's way more than crab cakes and old The Wire references.
The centerpiece of the city's brew scene is undoubtedly Flying Dog, the iconic brewery that put Maryland on the brewing map back in 1990 and has continued to pump out inventive beers, including one with Old Bay (the label art by Hunter S. Thompson collaborator Ralph Steadman probably helps). Brewer's Alley shells out its kolsch and IPAs in the very same building that housed Frederick's original brewpub back in 1901, Monocacy brings the sour with its refreshing gose, and Rockwell keeps things new with a roster of beers that embrace the beer cocktail movement. Things even extend into the country, where nearby Milkhouse takes the farmhouse designation literal. Hey, any excuse to go through a covered bridge is a good one, especially if it means beer.
While you're there: You'd be doing it wrong if you didn't do some sort of Civil War-related activity, like visit the Monocacy Battlefield or the Museum of Civil War Medicine, which apparently included more than just lopping limbs off willy-nilly.
