I am afraid I am not much help to the French wine trade, as I have two thirds of a glass, and top it up with water, with my evening meal. I have had periods of my life when I was not as happy as I am now, and I drank for oblivion - it didn't help, of course. I never want to lose another day of my life because I have such a bad hangover (alcoholic poisoning) that I cannot move.
I did share a glass or two with my family in New Zealand but they are not big drinkers either. New Zealand wine is excellent, but expensive if exported.
I have noticed when lunching in a restaurant here that many people leave wine in the bottle when they leave - I wonder what happens to it!
