Tree House Brewing Company was established in 2011, growing from a modest homebrewing operation into one of New England's most celebrated craft breweries. The brewery began in Brimfield, Massachusetts, before relocating to Charlton, MA, where it has built a devoted following among hop enthusiasts and craft beer lovers across the United States. Despite its relatively short history, Tree House has become one of the most talked-about names in American craft brewing. Tree House is widely recognized for its New England-style IPAs, celebrated for their juicy, hazy character and intensely hoppy profiles. The brewery's reputation was built on this signature style, though its growing popularity has since allowed it to expand into a full range of classic beer styles. Notably, Tree House began mixed fermentation brewing efforts as early as 2013, capturing a native yeast culture to develop complex fermented beers alongside its core hop-forward lineup. The brewery opens its taproom on Thursdays, Fridays, and Saturdays, drawing dedicated hop heads from across the region. Standout beers include King JJJuliusss, an Imperial India Pale Ale, and Thrice Baked Barleywine, both of which have earned international recognition. Tree House has been recognized as the largest craft brewery by volume in Massachusetts outside of Boston, packaging and selling more beer than any comparable brewery in the state in 2020.
