Wine tour around Santiago?

[PhillyCook]

My husband is going to Santiago for a conference at the end of June. Sadly, I can't accompany him. As my consolation prize, he's promised to bring me back some delicious wine -- of course, in order to do this, he plans to go on a winery tour or two.

Any suggestions for a good winery tour? He needs something organized -- not going to rent a car and head out into the hills by himself.

Also, any suggestions for not-to-be-missed eating experiences would be welcome. I'll live vicariously through the descriptions.

Thanks!
