We went on the Barrel Tour and Tasting. It is a beautiful setting and the buildings/spaces are great. Don was a fine guide, striving to make it interesting. However the tour had 20 people and one guide, pouring for all of us, keeping things moving, and ensuring we were done in the hour. We had no time to discuss wine, ask questions, or leisurely tour. It is not inexpensive ($40) and we would have hoped for a more interesting hour. (A second tour guide might have fixed the problem, but we saw few helpers around -- perhaps limit the tour sizes?) We have done 5 other tours over the last two years and this was the only one with more than 8 people. The others were all more personal and more interesting. They also focused on the wine more and less on the building (we did sign up to learn about Buena Vista wines and except for the name Sheriff, I know very little now).
