You don't have to be a connoisseur to host a wine tasting -- not that it hurts, of course, but anybody can bring together some friends to explore the bouquets, the bodies and the finishes of some classic bottles.
Wine tastings are not willy-nilly gatherings. They are organized, prescribed events that take thoughtful planning and, typically, at least a little research. Since printed information sheets and score cards are standard, this event is probably not a last-minute deal, but if you're looking for some good-old highfalutin fun, a wine-tasting may be exactly the way to go.
Both living rooms and restaurants can be perfect locales for a tasting. Try to make sure your guests are all at similar levels of wine expertise so everyone feels at home.
Next, a pairing.
