On our latest IPA, we decided to highlight the Columbus hop varietal. Also known under the proprietary names Tomahawk and Zeus, Columbus is a fairly new high-alpha acid American strain with pungent resin, pine, and citrus flavors. We also added an ounce of Citra to the mix for a hint of tropical fruit.

Otherwise, the recipe is identical to our last couple of IPAs. We adhere to the contemporary West Coast philosophy on IPAs, aiming for a very subdued malt and yeast profile so that the huge quantity of hops can really shine through. We've been pretty happy with the results.
