The simple answer is that drinking wine (or any other type of alcohol) after a massage is not going to have the effect you would desire it to. Instead of making you feel more relaxed, it’s probably going to have one of three negative effects: make you uncomfortably intoxicated (think hangover), make you sore the next day, or make you feel dehydrated and ill. Dr. Steve Jones provides some science behind these effects on Quora.
When you’re getting a massage, you are relaxing, but your body (and your massage therapist) is getting a work-out. After a trip to the gym or a rigorous run, you obviously don’t reach for the wine; until you’ve re-hydrated with either water or a sports drink, alcohol isn’t even something you desire.
So just think of a massage as a very relaxing work-out. In fact, you’ll feel so relaxed that you’ll want to save that bottle of Chardonnay for another day.
