Welcome to the club! There are many things that suck about getting older, this is one of them. I could put down a bottle of wine in my 20s and part of my 30s. By 40, three glasses = definite all day hangover, 2 = tired and slight hangover. There are certain wines I can tolerate much better than others. Generally, lighter reds with lower alcohol (red Burgandy, Pinot noir) are better than something like a Cab Sav or any white wine. Also, French and Italian wines seem to make me less hungover than anything American. I was in Italy earlier this summer and had 2-3 glasses of wine a night and never felt it the next day.
I order wines from
https://www.dryfarmwines.com/. Everything they sell is organic and lower in alcohol and sugar. I really do see a difference with how I feel after drinking these wines vs., say, the two glasses of Sonoma Pinot I drank at a restaurant this weekend. However, I’ve gotten to a point where I don’t finish my quarterly box of wines before the next one arrives. Drinking just isn’t as fun when you pay for it the next day.
