The trend for many modern breweries is to rotate between a wide variety of beers, retiring or changing recipes that don’t work (or don’t sell well) and constantly introducing new beers to keep draft lists fresh and exciting. Many breweries make anniversary beers as part of this rotation, usually a new beer to celebrate each year that the brewery has been in business. Many of these beers are one-off brews, but the most popular releases can be revisited on subsequent anniversaries or even added to the core lineup. Tree House has a slightly different take on anniversary beers. Head brewer and co-owner Nate Lanier brewed a pale ale called Beneficiaries of Chance to celebrate his wedding to Tree House retail expert Lauren. Each subsequent year he has brewed a new beer to celebrate their anniversary, and he usually re-makes new batches of some of the previous anniversary beers. This year Tree House released I Have Promises to Keep, a double IPA brewed with Nelson and Citra hops and brewed to celebrate Nate and Lauren’s fourth anniversary. They also remade their first anniversary beer, In Perpetuity, an IPA also brewed with Citra and Nelson hops. Both beers are available on a limited basis on draft in in 16 oz cans.
Tree House In Perpetuity pours super hazy light orange with a small white head. The aroma is all hops, tons of citrus. The bold hops lead the flavor, notes of lemon-lime, white grape and stone fruit along with a mild but noticeable bitterness. This is complemented by a light malt backbone, touches of white bread and biscuits. In Perpetuity is medium bodied and super drinkable, not over-kill boozy at 6.7% ABV. The finish is crisp and pretty clean with some lingering hops. In Perpetuity is a very good NEIPA, not my favorite Tree House beer but still a quality addition of their lineup. Hoppy Boston score: 4.25/5.
Tree House I Have Promises to Keep pours murky light orange with a solid white head. The aroma is solidly hoppy, loads of citrus and tropical fruit. These hops lead the flavor, notes of mango, guava, orange and lemonade along with a soft but present bitterness. This is balanced by a solid malt backbone, hints of bread dough, honey and oatmeal. I Have Promises to Keep is full bodied and packs a little pop at 7.9% ABV but drinks pretty easy for a bigger beer. The finish is remarkably clean for a DIPA, just a bit of lingering hops on the tongue. This is a really enjoyable DIPA, tons of flavor but not overdone. Cheers to four years and to many more years of happy marriage (and delicious beer) in the future! Hoppy Boston score: 4.5/5.
