I'm becoming quite the beer snob in recent years, and have made it a habit to visit as many breweries as possible when visiting a new city. Naturally, I subsequently publish brewery guides after the visits (like my Cincinnati breweries and Cleveland breweries articles to name a few), and plan on continuing this trend wherever possible.
I've visited Frederick, Maryland, a few times over the years and have been able to try several of the city's unique breweries. One thing jumped out at me from many of the ones that I visited in that they had large draft lists with an impressive variety of styles (something I can't say for beer scenes in other cities).
So if you find yourself in the area and are looking for a great beer, you may want to consider one of the following!
