I finally did a side by side of the clone I brewed and the real deal.
-Clone was slightly more bitter (I got a little happy with the Magnum and ended up putting a full 2 oz in, which probably has a little to do with that.)
-The real Ruination had a slightly stronger hop aroma and flavor. Just slightly.
-The real Ruination had a thicker, more dense head, with slightly better head retention. The clone had a good head, just not quite as thick and creamy.
That was about it. Color was spot on, clarity was pretty close, with the clone having just a little haze to it, but just ever so slightly.
I don't have a judge's trained palate or anything, but these are the things I noticed.
