Last year I googled for day trips out of Paris, specifically to Giverny. However, there were tons of bus tours to the wine area, especially Champagne region. It is about one and quarter hours from Paris. It has train and TGV access. You could take a train and rent a car at the station or try a bus tour. If you go to Champagne by car, research when things are opened. I have been doing that lately, and alot are open only on weekends. Don't go when everything is closed.
Another good option is the Loire valley, home of Chinon and other great wines, plus all the castles.
