There are not. Fresh is always best.
Now, I don't know what kind of party you're throwing, but at most big house parties people bring their own shit or are responsible for finding something they like amongst the offerings. If you must, whip up a pitcher of something and leave it out, then people can take as much or as little as they want.
If there's more than about 6 people at the thing and they're asking you, the host, to make them a drink then tell them to fuck off.
