Tree House Brewing Company is a brewery located in Charlton, Massachusetts, approximately 60 miles west of Boston. It is considered by some to be amongst the best breweries in the United States, including public beer-rating sites like Untappd (ranked 8th best brewery in the country) and Beer Advocate (brew 3 out of the top ten beers in the country), as well as sites including Forbes, the Boston Globe, and Thrillist. Founded in 2011, the brewery was originally located in Brimfield, Massachusetts, then moved on to Monson, Massachusetts in 2013, before a multimillion dollar project landed them at their current site in 2017. Tree House is a non-distributing brewery—it is only available to buy on site—but given its popularity, lines at the brewery can run an hour or more on certain days.
