Before you actually get to the fun part of trying the wine, you need to observe its colour. Tilting your glass into the light and against a white background allows you to notice the shades of the wine.
Most people think a darker colour would mean the wine was a fairly aged one, but it’s actually younger wines that tend to look deeper and richer in colour. A lighter flush, almost with an orange glow, means the wine is older.
The age of the wine doesn’t necessarily establish its quality, but it still helps to be in the know.
