The older you get, the more it will become more commonplace where instead of beer/straight up hard liquor, you will end up in situations with wine and members of the opposite sex. Not all women are hard drinkers and given safety concerns, they won’t always drink hard liquor in front of you. Wine, on the other hand, is a crowd favorite with women of all ages and eight out of ten times, she’ll use that as the sensual icebreaker/truthteller when dealing with you.
You guys need to learn your wines. I’m not saying that you need to memorize everything from your Riesling’s to your Sauvignon Blanc’s (though it helps), you should learn how to distinguish between the qualities of Red and White wines, and what foods go great with them. You may end up knowing more than she does on the matter and impressing her, leaving her with the curiosity of what else you may know about the world. Drink responsibly, of course.
