Also referred to as the "finish," the aftertaste is the flavor that lingers in your mouth after you've swallowed a sip of wine. As a general rule, the better the wine, the longer—and more enjoyable—the aftertaste. When you see wine judges staring off into space after sipping a wine, it's the aftertaste they're assessing; aftertaste is a crucial factor in judging a wine's quality. The aftertaste of a great wine will linger for several seconds, allowing maximum gratification of its rich, complex flavors and aromas.
