-version_description="Brewed at the Benelux microbrewery, this IPA has huge floral, citric and resinous hop aroma, simply an amazing nose. The flavor is very fresh with a light caramel malting touch completing a strong body. Huge amounts of hops, lots of grapefruit, lemon and oranges. This is an outstanding IPA!"

+version_description="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."
