Wine experiences in Paris or through a day trip?

Paris is not a wine region but you could do a day trip to Reims for the Champagne Houses.

It's possible to do Reims as a day trip, but it will be a loooong day and a rushed to boot. You should be able to do it justice with a one night stay if you get there early in the a.m. and leave late the next p.m.

If you go, two restaurants come to mind. Across from the cathedral (which is interesting because of the Chagall glass) is Au Bureau with outside tables and is good for lunch. The other is Le Gran Café on Place Drouet across from a hotel with a similar name. Great food -- ate there twice!!

We went to the Martel champagne place and found it to be very interesting. It is easy to get to on the city bus from the area of the train station.

The Museum of the Surrender (?) where the peace treaty ending WWII is also well worth a visit.

In Paris, book a wine tasting class at O Chateau. Very informative, and fun.

The part of the Loire Valley closest to Paris by train is an option, but like Reims, it would really require an overnighter.

My experience has been different from several above: I have done Reims as a comfortable day trip from Paris. The TGV (high speed train) gets you from Paris to Reims in about 45 minutes (it hits 150 mph on some stretches).
See the Day Trips section of Rick's book, Paris, for the details.

For wine bars in the city, you may enjoy these articles (but note the dates):

Rick's book also lists a few in the dining section.

Thanks everyone for all the comments. I think we will do an overnight trip to wine country :-)
