Stone Ruination Tenth Anniversary IPA was created as an homage to the almighty hop. As the celebrated Stone Ruination IPA approached its 10th birthday this June, we knew we had to do something special, so we cranked it up from 7.7% to 10.8% and used twice as much hops–a whopping 5 pounds per barrel, including a pound each of Citra and Centennial in the dry hop.
