I kind of look at two group situations.
If the beer that is going around is bud or miller lite, or something equally generic, then its a party where people just want to get drunk and play drinking games. Not a fan of that type of get-together. Not even when I was in college. The only wine I see at those parties is in a box, or 5 dollars a gallon, and people are immaturely chugging it to get drunk.
If it's a get-together where people are more interested in lubricating their tongues, so to speak, around good company, then I see an equal mix. The beer is almost always something on the pricier side, or a beer that isn't designed to be shotgunned. Same thing for the wine. Both drinks are enjoyed for their taste and nuances, rather than their effects. That's my type of party. The conversation covers anything, from political philosophy, movies, cooking, and religion, all the way to sex, hobbies and other personal interests. People care more about what others are saying than listening to themselves speak.
I love spending time around young people who can appreciate the second type of party, rather than the "let's get wasted and make fools of ourselves" type of party.
