Without being an "inveterate drinker", wine is (was) part of our culture (I am the grandson of a winegrower), and even if I am not a regular drinker, I found it quite normal to accompany a good dish of a little wine, when I entertain at home or during festive meals.
Indeed, certain products consumed regularly by our companies are part of the culture which is transmitted in a consistent manner from generation to generation. Wine is not the only cause, (generally alcohol), cigarettes or cigars (for the wealthy) are also part of it, or coffee, the jug, etc.
It is only very recently that their toxicity has been recognized, but this is not to say that a brutal change can take place (it is only to look at anti tobacco campaigns and their relative effectiveness.) which works best remains the significant increase, or even the excess of their price, which is dissuasive for part of the youth with low means and the middle strata. But behind it, there is a whole industry which lives (sometimes very well) of the diffusion of these drugs and that concerns a lot of producers and consumers… and therefore potential voters.
