The Belgian Black is called 1554 and it is one of my absolute favorites. Also the loft is fantastic. If anyone ever gets a chance to go to Ft. Collins, CO they should definately make the trip. The new belgium brewery has a fantastic brew tour and lots of free samples. Some beers they offer are only available to taste at the brewery. They have one called Transatlantic Kreik. It looks like cool-aid and tastes very strongly of cherries. Apparently it is brewed in Belgium and shipped accross the Atlantic. At first it was supposedly terrible and they threw a bunch out, but then they found some they forgot over a year later and they tried it. It turned out great, so they bottled it and made it available. It's pretty rare and definately a unique beer experience.
Also, while in Ft. Collins, check out O'dells Brewing Company. They make Easy St. Wheat, 90 Shilling, and the new wood flavored Five Barrell. All very good and another good tour just a few blocks from New Belgium. There is another brewery there called the Ft. Collins Brewery that just started selling beer in Laramie, I don't know much about them but I've tried their smoked beer and it was pretty good.
And if you want to make it an extensive tour and get as drunk as possible for free, the Budweiser plant is just southeast of town too. Two free beers.
