The colour of a red wine will give a clue as to the age of the wine. Many red wines start life as a deep purple colour, sometimes almost opaque. With time, however, the wines lose this youthful intensity, and begin to take on a paler, tawny, brick red hue. Initially this appears at the rim of the wine, but as the years go by the whole wine will take on this colour, fading to a brick red or brown.
