Which wines should you buy for a party?

For larger parties, you cannot go wrong with Malbecs from Argentina, Cabernet Sauvignon and Sauvignon Blanc from Chile. They are familiar to most drinkers, widely available in stores and make easy pairings with wide range of food. If you want to get more adventurous, you can go for Portugese and Spanish reds and Austrian whites, they provide great value and are consistently superb.
