It is absolutely worth checking out City Brew Tours. We had the opportunity to visit four breweries, learn a bit about the history of beer and the brewing process, have a beer pairing dinner, and we met some really great people as well. Our group was fun, some local people, some people visiting Baltimore for the first time. Our guide, Emerson, made the whole experience more enjoyable, he is very knowledgeable about beer, and a lot of fun to be around.
