Best alcohol for party?


I am a non-drinker but need advice on what to purchase for a party of 20-30 moderate drinkers mixed with non-drinkers.

Moderately priced (I am not cheap but not looking for the most expensive suggestions) whiskey, bourbon, vodka, gin, and wine.

Thanks.

Grain alcohol mixed with whatever was the most popular at the frats back in college.
Good responses above, but an important factor that hasn't been addressed, which will influence people's drink selections, is the kind of food that is being served. It would be helpful if you could give us some idea of that.

Also, provided that it is a suitable match to the food, IME the most popular drink selection among the type of crowd you appear to be describing is white wine, so I'd purchase a goodly amount of that. There are lots of good choices, but you most likely can't go wrong with any French white under the Jadot label that fits within your budget, Jadot being a négociant.

Simplify your party making. Just serve champagne. Also provide bottle water, for the non drinkers. I've done this for many parties over the year and only once did I have someone complain.
Thanks again for the additional responses. A mixture of dips, shrimp, sausages, and fruitcake will be served. The wine suggesions seem smart.
