The Etiquette Tip To Keep In Mind When Serving Wine In France - Tasting Table
Briefly

In France, it's customary for men to pour the wine for the women present - this is just considered polite, like a man holding the door for a woman. Throughout the meal, the host will refill any empty glasses, so anyone who does not want more leaves a tiny bit in their glass.
Even if they don't, everyone at the table might want to do a little "cheers." This is "santé" in French, meaning "to good health," and you should always make eye contact with whoever you're clinking glasses with.
Don't put ice in your wine even if you tend to prefer chilled wine at home. This is all about savoring the wine the way the vintner intended.
All wine is typically finished by the time the meal is done, at which point the imbibing switches to after-dinner cocktails and spirits called digestifs.
