There are many aspects to tasting wines. When starting to taste a wine first gently swirl the wine around in the glass. This will activate the wines aroma in the glass. Place your nose on the rim of the glass and sniff lightly and long. Then take a mouthful of wine, making sure to coat your mouth with the wine. Swish it gently from side to side in your mouth. Then spit the wine out or you may swallow the wine.
This is the basic way of tasting any wine. If you are starting to enjoy wine you may want to purchase a wine journal or start writing in a note book of your choosing.
