i've thrown a dozen of these parties myself. so if i may, i will nominate myself as sosuave's resident wine expert
i wouldn't say it's "high class", i'd say it's "sophisticated". bascially, it's what grown ups do, although they are becoming more popular with the mid-twenties crowd. depends on the crowd though. i've been to W&C parties where they served jug wine.
The Wine Part
this is ususaly a "wine tasting" atmosphere. that is, people will bring wine (or it will be supplied) and ya'll taste it together. many times, there's a blind "voting" thing. if it's a "real" wine tasting party, the whites will be very limited. you should bring a bottle of the grape juice, even though it might not be expected.
if it's a paid and sponsored event, then the above doesn't apply.
pick up a bottle of 2000 Clos Du Val Cabernet Sauvignon. it'll set you back $25.00 and it's a winner (in my book). don't spend over $30.00! there's plenty of excellent wine for under this amount. don't u dare pick up a bottle of wine from your grocery store! it's all shyt.
if you want some other sure fire hits, i will oblige. but, get nothing later than a 2000.

The Cheese Part
yes, usually there is cheese--good cheese--because cheese goes well with wine. but there are other nicer things, crab legs, shrimp, patte, etc. again, it just depends. shyt, they might serve hot dogs and hamburgers--who knows.
The Snob Part
depends entirely on the crowd. one thing however, if you know nothing about wine, but show enthusiasm in learning about it, people will be very happy to teach you. definitely DO NOT pretend that you know about wine, if you don't!
it turns into a party like any other after the booze starts flowing. whatever you do, don't get drunk! let the other people get drunk.
they're really not as snobby as you might think, unless it's full of very rich people.
incidentally, wine tasting gigs are fantastic places to meet chicks. and if they like wine (good wine), chances are high that she either is somewhat sophisticated, or wants to be.
so, is this a real W&C party or just a poor excuse to get drunk?
you definitely need to find out what kind of party it will be and dress appropriately!
PS: shythouse advice for those who care: load up on 2001 Cabs! it's expected to be one of the best years in recent memory.
