But one day you grab a beer, uncap it and pour this quite malty IPA that has yet another special twist. Among its ingredients there's pine resin. I had Piris Resin Old School IPA with two of the people in charge at Instituto de la Cerveza Artesana, where this beer is brewed. I also drink one at home, on a warm summer night. Leaving apart the evolution it's had in two months, the sensation is exactly the same.
