We will be driving around Tuscany on June 29 - 30 (Sunday - Monday). Will the vineyards/winery's be open on Sunday? This particular Sunday seems to be significant?
I can't speak for Tuscany, but this past September we were looking for vineyards in Umbria that were open on a Sunday. Several we pulled up to were closed. We only found 1 that was open on Sunday.
I hope we can find at least one!
Check out Baracchi Winery in Cortona, they may be open on Sunday. If their website doesn't say, you can email to ask.
Most will probably be closed but it would be best to contact them ahead to find out for sure. There may perhaps one that isn't closed.
