How many wines should you serve? Allen says six is a good number—three whites and three reds—enough to keep things interesting without being overwhelming. Here, from left: A to Z Oregon Pinot Noir, $18; Penfolds Thomas Hyland Shiraz, $15; Mondavi Private Selection Cabernet Sauvingnon, $10; Mondavi Private Selection Chardonnay, $10; Santa Margherita Pinot Grigio, $23; Brancott Vineyards Sauvingnon Blanc, $11. Open the first set of bottles before guests arrive (keep whites in coolers or buckets so they stay chilled). Have a corkscrew or two handy.
