Subtle aromas and flavors—fruity, nutty, spicy, or earthy—give each wine its unique personality. Sauvignon Blanc, for instance, may suggest grapefruit, lemon, apple, melon, fig, bell pepper—even freshly cut grass. To give your party extra kick, set out some of these fragrant essences for everyone to "nose" before they try a new varietal. Place 8 to 10 different essences in clear glasses and invite guests to take a good whiff.
