My husband and our two friends took this tour, our guide was Derek. Derek was great, super energetic and passionate about the brewerys, beer and his job in general, and got better with each brewery, going as far as suggesting places for dinner afterwards. We went to four breweries and there was 2-3 different tastings at each place, some places we had our own area other places we had to stand. All in all, tour was informative, Derek provided some historical info on Denver which was neat, and it was nice to get a chance to walk through the beautiful streets. Our tour went longer than expected, so our group dwindled from about 25 to 8 by the time we ended. We were impressed with 3 breweries we visited, but were disappointed that Rock Bottom was our last stop, as it is a chain restaurant and we were hoping to visit only smaller, unique craft breweries.
