Generally, wine is served in glasses with gently curved rims at the top to help keep aromas in the glass. The thinner the glass and the finer the rim, the better. A flaring, trumpet-shaped class dissipates the aromas.
When tasting wine, hold the wine in the mouth for a moment or two and then either swallow it or, preferably, spit it out, usually into a spittoon. A really good wine will have a long aftertaste, while an inferior wine will have a short aftertaste.
