We were there in the spring. You don't really need to plan it all out. Base it on the weather, and what you are feeling that day. If you are into wine, then you have to take advantage of some of the great wines mentioned earlier in the thread. Bring some back, the comparable cost here is three or more times what you will pay there.

Take your time and enjoy the trip. Even food in the highay rest areas is way better then most of what you get in restaurants here in the states. Bring a kinfe with you, get some of the local meats and cheeses, and snack away. I believe it will be a very long time before I'm able to find wild boar in my local deli.
