Each arrondissement, each neighborhood, even, in Paris has its own wine bar. Some of these have become slick spaces where wine is served in doses, by machines. And others, where the red-faced barman behind the counter seems to know nothing but how to make a generous pour.
Popular, too, are the natural wine bars. These wine bars specialize in “vin naturel” which is something akin to organic wine but different. Natural wines are made by following a very strict cultivation and vinification process so that only purity is unleashed once the bottle's cork is disgorged. There are many who are fans of these wines and France has some wonderful “vin naturel” producers.
For those of us who enjoy simply hanging out in a comfortable space and talking with friends over a glass of wine, Paris offers many wonderful wine bars for this. Iconic ones, such as Willi's and the Baron Rouge, rub soldiers with new cult faves such as Frenchie's and Septime and Verjus. Spending an evening discovering, even falling in love with a new French wine, is something you just gotta do while visiting Paris.
And if there are certain regions you prefer over others in France, in terms of their wines, you will be able to hone in on some of the wine bars specialized in Bordeaux (L'Ecluse), or Burgundy (Les Climats) or Alsace or the Loire (Sancerre). And there is one in the Marais (L'Enoteca)that is especially well-known for their Italian wines, too.
