As far as the regular releases from NB go, none of them will knock your socks off. But they are all something that I'd drink every weekend. To me, that makes New Belgium a damn good brewery. I'm not huge into sours and specialty releases, but what I've had from them has been outstanding. That makes them a great brewery as far as I'm concerned.
If you're ever in Ft Collins, definitely visit/tour both NB and Odell. Odell is easier to get a tour, and a really cool place especially when the weather is nice. NB tours book months in advance, but you can show up any day of the week, get super cheap NB beer and play games all day long. It's a really fun place to kill an afternoon.
