Hold the glass up to the light and look for transparent wetness left on the glass. The nose is much more sensitive than our palates. The nose will tell you seventy-five percent of what you need to know about a wine. You can taste but four sensations, you can distinguish among 5,000 smells. The esters carry the wine's aromas.
Most people find it difficult to describe what they have smelled.
If the wine is pleasant, try and relate the smell to something you like. Does it smell fresh, fresh fruit or berries, nuts or flowers or spicy. Your taste will be affected by the smell. The first impression will be the sweetness in the wine. The sensation is short and intense.
