A wine's body is measured by swirling it around the glass and seeing how long it takes the wine to flow down the sides. Full-bodied wines are heavy and come down the sides of the glass in sheets. Light-bodied wines are not heavy and will not cling to the sides of the glass when swirled. The nose or smell of a wine describes the perfume it gives off in the form of esters. It is determined by the aromas and bouquets.
Aroma is the part of the smell derived from the grape, as for example, a flowery nose.
Bouquet is derived from the aging of the wine in the cask and in the bottle, as for example, a woody nose. Judge the nose by sniffing the wine in an open glass. The nose can range from very pronounced to moderate to subtle. A wine is lacking nose if there is no detectable smell whatsoever. Fresh nose - wine is pleasant with youthful charm.
