Although wine is usually classified according to its color – white, red or pink – the matter is more complex than it may seem ‘at first sight’. There is a wide range of parameters that can be analyzed with the view to draw a whole series of conclusions.
Red wines can range from pink and violet tones to opaque and almost black. The whites in turn can show from an almost colorless pallor to an intense yellow color. Pinks, on the other hand, can range from a very salty tone to a deep pink tonality.
When turning the wine in the glass we can see at a glance the body and texture of it. When we stop turning it we can see the ‘tears’ or ‘legs’, which are nothing more than the drops that slide through the inner walls of the cup, and which indicate the density. All this is due to the amount of alcohol that contains the wine, presenting a high content in those “tears” that are formed more dense and consistent.
A priori all wine should have a clean and shiny appearance and, unless it is a special elaboration, it is very rare to find a matte wine, cloudy or veiled, symptoms that can anticipate some type of defect.
With the age the color of the white wines darkens and they can get to take a brown tone, which indicates to us that they have entered in phase of decline losing all its fruity and freshness. The wines with higher natural acidity have a longer life and can be kept in perfect condition for years.
In a white, the pallor indicates that it is a very young wine, which has not been slow to be bottled and consequently has not received aging. The meniscus in these wines is usually almost colorless. If, on the contrary, the white wine is aged on lees or in wooden barrels, the resulting color will be a more intense yellow and a golden rim.
The reds the decrepitude produced by age is manifested in a loss of chromatic intensity, to the point of adopting a brown hue and a border of onion skin color that may even become transparent.
If a red has little chromatic intensity, it can be a sign that it comes from a cold climate. The deeper tones, this is also valid for whites, usually indicates that the wine has been made in a region of warmer weather. In some cases, it is necessary to take into consideration the type of grape used, because there are varieties with less or greater chromatic loading.
