I've written loads of other reports like the ones I linked to in my previous post and they are all about exploring the countryside in just about every direction from Paris within a radius of about 100km. Since you'll have a car you don't need to settle on one village but you can see several. In any non-touristy village you'll likely be finished seeing all there is to see in less than 20 minutes anyway.

The area around Paris isn't wine growing territory but you could head east in the direction Epernay and explore champagne territory. I've been exploring out there recently and along the Marne river and close to Epernay it seemed that just about every village, even the smallest ones, had no less than a dozen champagne houses. Most of these require an appointment to visit but I did find a few villages just south of Epernay where you can drop in as they have reception rooms for drop-in tasting. Those villages are Cramant, Avize, Oger, Le Mesnil-sur-Oger and Vertus. I don't know that they all have drop-in tasting but we stopped in Oger at the house of Jean Milan. You can also buy an excellent bottle of champagne for as little as 16 euros. Here's a tourist office website for that region:

And for the place I did the tasting (and bought several bottles):

As for local produce, you might want to have lunch on a local farm in the countryside. This type of restaurant/farm combo is called a ferme-auberge. They are also places for overnight lodging. You'll probably need to reserve and also check their hours to see if they're open during your visit. This website (in French) will assist you in finding such a place, as well as places where you can find locally produced products:

I'm always exploring the countryside near Paris so if you need further assistance feel free to ask.
