A couple of years ago, I bought two bottles of Utopias.
One, I opened immediately, and was pretty much unimpressed. It had a dull taste to me.
The other bottle sat in my beer closet, unopened for two years. I opened it yesterday.
The extra time in the bottle seems to have improved it. After 'maturing' a bit, it is a sour/tangy beer, that pairs very well with barbeque. The main flavor was sour cherry, with a vaguely noticeable trace of chocolate or coffee. Very pleasurable, if you like sour beers.
I'm glad I let it sit for awhile.
