The world’s best IPAs, according to Untappd’s ratings, include three beers by Massachusetts-based Treehouse Brewing Co. The brewery has the top-rated IPA on Untappd overall and three of the top five IPAs. But two other notable breweries also have top five honors in the IPA category: Russian River Brewing Co., in Santa Rosa, California, and Fidens Brewing Co. in Albany, New York. Russian River Brewing Co. has the second highest-rated IPA, and Fidens was tied for fourth—but notably had another beer, called Triple Jasper with Nelson, that just barely missed the top five.
