Excellent all around: atmosphere, guide, co-tourists, locations, beers, etc. Thanks to Barry for being an outstanding host and leader, as well as knowing -- and enjoying sharing with us -- a lot about the brewing process and each of our tasting beers.
My boyfriend and I live in Lorton, VA (local). We took the day tour on Wed 30 December, when we'd taken vacation for the holidays. The clientele on our tour was fairly young (20s-30s) couples and small family/friend groups. We had a full tour: 13 customers + our guide in the 15pax van. The ride was a bit tight, but with social, courteous and interesting people (which we had), that didn't matter. It actually contributed to the group's overall shared experience -- it made the day more fun.
We hit four breweries &/or brewpubs, just as stated on the company's web site, and had several beers to taste at each location. Total was ~17 tasters. The tasters were generous pours at each stop; not many folks finished them all! Everything was either exactly as advertised, or better. Some folks on the tour commented that they would have preferred a heartier lunch -- which was included in the cost of the tour -- but what we had was delicious. (My opinion: it's a beer tour, not a heavy meal reservation. I would far rather eat a good breakfast beforehand and have more interesting beer tasters than get a large "included" lunch and either (1) have fewer beers offered, or (2) be too full for the after-lunch beers.)
I heard that Brew Tours' expansion to DC is relatively new (2015). Hope that the business and its relationships with DC brewers continue to flourish. I would recommend this trip to anyone who enjoys drinking interesting beer, learning and discussing the science and history of beer, and a quick (5-hour) introduction to the scene in the Washington, DC area.
