223ca7c5 47 "The Époque Opaque is a black IPA from Trou du Diable brewery. The nose is eerily reminiscent of the coffee crisp candy from of our childhood. These strong mocha accents are present on the palate, which are quickly subdued by Japanese and Australian hops leading to a final state of satisfaction enjoyable for any fan of bitter beer."
