Cooking and/ or wine tasting with the locals

Our experience with wine tasting around Florence last May was with all tourists. It was not all Americans but was tourists from everywhere. We did find it necessary, unlike the US, to make reservations in advance for the tastings at the source. Sometimes there were little booths off the road that had walkup wine tastings but for the most part the castles and production areas needed a reservation and often a fee.

You might find something here that would fit the bill.

As a local, I suspect that country wineries are mostly a form of tourist entertainment. There is nothing wrong in tasting wines in front of hills, but most locals simply do not have time and money for it.
The same goes for cooking schools. Of course locals may attend professional cooking schools, but I see little scope for a local to attend a one or two days basic tutoring.

But - if you look, there are groups of persons that like to share their cooking in their private homes with hosts. Probably this is the closest thing to what you are looking for. Start from: http://www.homefood.it/en/

I might also add Anne Robichaud at http://www.annesitaly.com. She is in Assisi, Umbria, and although this in not the region you are in, I am just offering it as a suggestion. She is a guide, but also does do Rural Life tours which includes dinner in a local farmers home, not an agriturismo, and I am fairly certain you can arrange cooking classes all in authentic Umbria farm tradition.
