Tree House Brewing Marks 14 Years of Green With Week-Long IPA Celebration

A beer that started as a 5-gallon kitchen homebrew is now being poured across seven locations simultaneously. Tree House Brewing Co. launched a week-long celebration of Green, its original Tree House-style IPA, an occasion that doubles as a living case study in how far the Massachusetts hazy IPA movement has traveled in 14 years.

The event centers on Green's velvety, tropical character, amplified across all seven Tree House locations and paired with a revival of the beer's original can label. That packaging callback is more than nostalgia: it anchors the celebration in the specificity of where the beer began, a home kitchen, and the scale it eventually reached.

Green's arc mirrors the broader Tree House origin story. Before co-founder Nate Lanier started the brewery, he was already deep in the craft beer world, and his trajectory shifted after tasting Rochefort 8, the Belgian Trappist quad that sparked what Tree House would later describe as a brewing odyssey. That obsession with transformative flavor eventually produced Julius, the 6.8% ABV American IPA that originated in a humble kitchen in Ware, Massachusetts, and went on to build the Tree House name. As the brewery itself puts it: "Tree House is the House that Julius built."

Julius set the template. Designed to fuse American hops' fruit-forward intensity with a specially curated yeast blend, it became famous for converting drinkers into devotees of the Tree House-style hazy IPA. It remains available at all five named Tree House locations, Charlton, Tewksbury, Deerfield, Sandwich, and Woodstock, while supplies last.

Green's celebration this week carries that same origin-story weight. The revival of its original can label during the seven-location event positions this not as a routine release but as a deliberate look back at the homebrewing roots that the entire Tree House catalog grew from.
