I know wine has resveratrols. But if it’s just alcohol you want, you could try switching to an unsweetened liquor instead of wine. I can’t tolerate sugar, and to me wine is sickly sweet and makes me react more than candy.
I love wine, but only with food. Usually 1-2 times a week. Plus, I'm in high dollar, technical sales. Wine is often a "job requirement".
When I just want something to drink, I usually have bourbon on the rocks, or Canadian whiskey and Diet Coke. It's the fewest calories.
Interesting angle you have with gut bugs. I've often believed they play a more important role than most people think. I travel all over the world... I have mixed up gut bugs.
