This might even underestimate the actual effects it already has.

I grew up in a European wine-growing region.
Compared to my youth in the 80s, harvest season now is 2-3 weeks earlier on average.

Vines already blossom much earlier during early summer and the ripening process of the grapes is accelerated.

Also there are shifts in types of grapes that can cope with the changed micro-climates.
E.g. Riesling grapes, dominant type here for more than 1000 years now and defining the landscape of many German valleys, will likely be gone within a few decades.
