Fill your glass about a third full and hold it up to the light or against a white background. You are looking at the colour - The deeper the colour the fuller the wine will be.
Place your nose right inside the rim of the glass, and inhale deeply. Try to identify the individual aromas.
It could be any number of things fruit, chocolate, and spices. This part takes some practice.
Holding the glass by the stem - so your hand doesn't affect the temperature - gently swirl the wine around the glass.
Smell again to see if any other aromas have been released.
The last step is tasting. When you take that sip take in a little air at the same time.
Let the wine rest on your tongue before deciding whether you like it or not.
