It's all about the taste...


Sniffing: As you pour the wine into the glass, look at the way the colour changes from the rim to the bottom. Catch a preliminary sniff of the wine.
Swirling: Hold the wine glass with your thumb on top of the base and the rest of your fingers below, and gently move the glass clockwise. Swirling opens up the flavours and aroma of wine.
Viscosity and alcohol level: Swirl your glass again and check the speed with which the wine runs back down the side of the glass. This is an indicator of the viscosity of the wine. More viscous wines will have "legs" running down - an indicator of the alcohol level.
Sniff the wine again. A much better aroma will hit your nose.
Take a small sip of the wine and roll it inside your mouth with your tongue, exposing it to all your tastebuds. Then purse your lips and draw some air into your mouth. This introduces air into the wine and unlocks its aromas again.
Swallow your wine and try to detect all the flavours in it.
