I can't seem to find what I am looking for by searching, so I thought I'd ask... Is there 1 winery near Siena that you would recommend? I am planning a day trip for my parents off of a cruise, and they will only have a short time - so, Siena, possibly San Gimignano and 1 winery would be good. Any suggestions?

Thanks in advance.

if your plan is to do both siena and san gimignano, you should probably focus on chianti. visits at wineries in italy are not short, so doing both cities and a winery in one day may be pushing the envelope.
