In what sort of glass should I be serving wine ?
Tulip-shaped or inward-curving glasses allow you to swirl, tilt and get at the bouquet effectively, improving your ability to appreciate the wine. In order to do this, fill your glass to no more than one-third full. The extent to which a wine releases its aromas depends on the shape of the glass.
What can the color tell you?
White Wines: become deeper (more golden) with age.
Red Wines: the more purple the wine, the younger it is. In young wines, the colour is usually uniform. The more brown, tawny or orange the wine, the older it is. With age, the colour is not uniform and is lighter at the rim of the glass compared with the centre.
