Well, I inadvertently "cellared" my Ommegeddon for the recommended 6 months and gave it a go last night.
It's a pretty nice beer. It doesn't possess nearly the funk that the bottle (or the name suggests), but that's more a criticism of the marketing than the brew. My wife, who rejects Jolly Pumpkin ales and Belgian geueze of various stripes, downed this with no problem and moderate enjoyment.
The flavors are pretty clean, with a slight sourness. The alcohol is pretty well-concealed for an 8% beer. While I'm game for another bottle, the price ($10-12, I think) stacks it up against some pretty tough competition, unlike the cheaper Ommegang products which give you a lot of bang for the buck.
