A wine’s colour and appearance change with the passage of time. This helps determine its age, it enables one to identify it as a young or an older wine. For instance, a young red wine, purplish red in the beginning, will evolve towards hues of orange-red as its gets older, before taking on mahogany or tiled red. Similarly, the pale yellow colour of a freshly-bottled white wine will reach over the years all shades of gold, and it can even turn to amber and to ginger.
