What breweries did you end up visiting in Colorado? Any review comments?
Locust Cidery in Denver - regional brand with a good selection of dry and off-dry ciders. We find most commerical ciders too sweet but these weren't.
Two Mile in Leadville - review is above. I'd be there regularly if we lived in the area.
Animas in Durango - nice setup, good food. Their Hogsback Black was really nice--they can it a dark ale but it tasted very schwartzbier-y to me. Crisp with a hint roast. Their Kolsch was good. Try one of the pasties, too.
Shamrock Brewing in Pueblo. Good Irish Porter, and their guest beer was Duchesse de Bourgogne! They also had a good guest cyser from Colorado Cider Co.
TRiNiTY in Colorado Springs - these guys have really expanded their wild and barrel-aged program since we left. Everything I tried was good. They have a lot of Brett beers, too, but their tart cherry chocolate stout was actually really well balanced, too. Bought a mixed 4-pack of sours to bring home.
I was also able to find a bottle of New Belgium's Adding Corners --- it's hard to find NB other than Fat Tire and sometimes their Tripel around here.
I really wanted to hit Terrain & Stem Ciders in Denver, Mad Jacks in Bailey, and Black Forest in Colorado Springs, but we couldn't make the schedule work.
