All but the very lightest of red wines should be served at room temperature. Very light ones are sometimes chilled. Red wine should also be allowed to breathe for 15-30 minutes before tasting. Don t try and taste too many wines in one session. After so many your senses will become confused by the previous tastings.
Most people agree that between six and eight is adequate for novices.
Taste from a tasting table. Make sure there is enough room for guests to move from one wine to another without getting in each other s way. Arrange the wines in the order that they should be tasted. You must decide whether to make the wine tasting seem as professional as possible, or be a casual gathering. My advice is make it casual, especially if it is among friends, and don t take it too seriously.
