Many spots in Jerez are not open on Sunday, but they were. We did a tour and tasting. The tour felt…read morea bit artificial, like if you went to Disneyland version of Spain instead of real Spain. The facility is very large -- the tour kept going and going. It was neat to see it. It started with a short motorized "train" ride which was mostly unnecessary and gimmicky. The tour was almost full, maybe 40 people. Then we had a tour guide walk us through various buildings and explain various things about the sherry-making process. She was not a very good tour guide -- she made mistakes / corrected herself and her English was so-so. If you can afford this large facility, fancy videos, etc you can afford better tour guides. Near the end was a video that was kind of cheesy, but used multiple projection screens in a very cool way. Then we did a tasting of five sherries; they were all pretty good.
Overall, the tour at Cayetano del Pino nearby was more authentic, friendly, small-group, and informative.
