When I grew up, we viewed wine as a beverage that rich people drink. Beer, and now hard cider, were beverages for "ordinary" people. There is a cultural shift in the perception of wine, and alcohol in general. Another factor might be the aging of the Baby Boomer generation and other demographic changes.
It is good that there is more awareness of the danger of abuse of alcohol. But that doesn't mean that we all need to become teetotalers. I once had a German friend, and he and his family had a glass of wine with dinner every night, including the kids. That was part of their culture. But if people only drink wine at parties or special events, consumption is a lot lower.
I would be interested in seeing a comparison in the sales numbers for wine, beer, cider, and hard liquor. It would also be interesting to see how that looks for different countries. I found this study by Gallup:

And a study by Pew Research:

The percentage of Americans who drink any amount vs. those who abstain entirely has varied within a fairly narrow range since 1939. Those with higher incomes are more likely to consume alcohol, as are college graduates (likely related to income). According to the Pew Research study, sales at wine, beer, and liquor stores has been rising, with a peak in 2020. Sale figures, of course, are affected by the price, so they cannot be used to compare consumption directly.
Since price also affects consumption, after several years of high inflation, the consumption levels for alcohol are likely to be down.
