My husband and I will be taking a tour of some wineries in the Napa valley the first week of September. I enjoy white wine.. chardonnay, riesling, and other white wines. We will be staying at the "Cottages of Napa valley". Are there any wineries close to where we are staying that have an excellent chardonnay that isn't going to cost me more then 20.00 a bottle. WE also don't want to spend an fortune on a few nice dinners.. Can anyone recommend a restaurant that wont empty our bank account?
