Best time for wine touring in Spain?!
Depends what you want to do/see. Also where you want to go. Fall is much more beautiful, but the spring can be nice two with all the vines beginning to show their leaves. The main question though is where you go. In the Penedes, you could see a lot most of the year, mainly because Torres, Cordineau, and places like Can Bonastre offer good tourism options. Right now though, Alicante is starting a new tourism campaign where some new wineries will finally be open to visit. Also in LaMancha a new project is very exciting where about 30 wineries have all agreed to be open to tourists(a big step) all year round.
Here's a link to the LaMancha Project: http://www.enoturismocastillalamancha...
