I cannot say enough about this tour! Ignacio, the guide, is absolutely wonderful. He is very friendly, excited, and knowledgeable, and speaks good English for any non-Spanish speaking visitors. His choice of winery was excellent and the wine itself was superb. We toured the whole winery while the guide informed us about their specific wine-making process, and then we had a casual tasting of 4 different wines (all full glasses).
Afterwards we had a picnic (with pre-purchased sandwiches and more wine) in front of a castle, after which we toured. We happened to be there for the Medieval Combat World Championship, which was quite exciting.
Finally, once Ignacio realized how badly I wanted to see a true La Manchan windmill, he performed a short detour to take our group to a hill with some windmills, over looking the hills of La Mancha. We stopped to take photos, enjoy the sights, and, of course, drink wine. It was the most peaceful and beautiful moment I have had in a long time.
This tour is great for all ages, for all wine lovers, and for all people visiting Madrid. The price is incredibly reasonable (especially after I did some research and couldn't find any wine tours under 200 euros a person). Again, Ignacio is the kindest person and I had such a fabulous time with him and the tour group.
Seriously, what are you waiting for? GO!!
