Step 1 - Hold & tilt the wine glass under your nose and smell once. 

Step 2 - Swirl the wine glass to release aroma compounds into the air and smell again in a slower, longer & delicate manner. Think about the aromas when smelling.

Step 3 - Tilt & move the wine glass to different positions around your nose. Fruit aromas are usually found on lower portion of the wine glass when tilted under your nose, while floral & earthy aromas are usually found on the upper portion. 

Note: There are 3 different categories of aromas: primary aromas derive from the grapes, secondary aromas derive from the wine-making, and tertiary aromas derive from aging and oxidation.
