Two Words: House Wine
Pick a couple wines—one red and one white—and stock up on both. Margrit Mondavi, wife of the late winemaker Robert Mondavi, says Sauvignon Blanc (which is light and fruity) and Cabernet Sauvignon (think cocoa and cinnamon) go with practically anything and taste good to pretty much anyone. Buying a 12-bottle case will save you 10 to 15 percent per bottle. And if you can, look for screw tops; you'll be glad not to be wrestling with a wine opener when the party's in full swing.
