I've been working on a clone of this wonderful beer for a while. While my beer isn't a clone, it is a good beer. I have based my recipe off of the Hop Karma and after three iterations came away with a 43 point (gold medal winning) beer. Here is what I brewed, using Wyeast American ale II, since that is the terrapin house yeast.
