Beer: Spaten Oktoberfest
Mixed drink: Rum & Coke (w/ some lime juice) or Long Island Ice Tea.
Wine: Sattui Vinyards Dry Reisling.
LionKing, if you like Reislings, I can't recommend the Dry Reisling from Sattui more strongly. It's absolutely amazingly good. Unfortunately, they don't actually sell to stores, you either have to go there in person, or buy it via mail order. Their website:

Kizzy, if you want another unique drink to serve people, try this one that some friends invented in the first college I went to:
7-Up
Limeaide
Vodka
Couple glugs of Rose's Lime Juice.
You'll know you have the mix right when the sweetness from the Rose's & 7-up just barely balances the incredible sourness from the Limeaide, and you can't really taste the vodka, but it hits like a brick.
