it goes through different steps and observations and can reveal hundreds of nuances and different colors.
a) First, you will have to determine that its surface called the disk shows its brilliance and mirror-like aspect. This will promise of a healthy and perfectly created wine. At that step, its robe will be determined; it may be dense, dark or translucent.
b) Secondly, the light should let appear a glossy and limpid beverage, deprived of cloudiness called the turbidity of the wine (NTU). This observation will show that the wine has been properly filtered or vinified. On the other hand, a “cloudy” or loaded wine would be broken, unfit or spoiled. This analysis will determine the robe of the wine.
