Wine can be divided into white wine, red wine and rosy wine according to color. However, the color of wine varies from grape variety, production area and brewing method to vary millions. Even wines of the same category will have subtle to significant differences in color. The reasons are as follows:
1. Brewing process:
The color of wine mainly comes from the skin soaking process during brewing, and the skin soaking occurs after the grapes are removed and broken! The thickness of the color depends on the length of the soaking time!
2, grape variety :
Different varieties have their own unique characteristics. Grape varieties such as Cabernet Sauvignon , Syrah , Merlot are usually dark black and blue and purple, while Pinot Noir and Grenache will be lighter.
3. Grape ripening degree:
Usually, the more ripe the grapes are, the higher the sugar content, the darker the color of the grape skin. In addition to the high alcohol content, the wine produced will also be particularly darker. The opposite is the shallower.
4. Acidity:
The color of wine is also deeply affected by the sour taste. The higher the sour taste, the brighter the red wine, and the lower the sour taste, the more blue and purple it is.
5, aged
Anthocyanin are phenolic substances that will condense with each other into larger molecules, and finally precipitate into rosperm. This phenomenon also makes the red wine gradually fade in the aging process because the red pigment decreases. The tannin in red wine becomes softer as the oxidation process becomes softer and softer as the aged ages, and it also turns the tannins from colorless to reddish brown, turning the red wine's color from purple-red to brown and orange-red. In old age, only a faint brick red is left.
The color of white wine is usually lighter, almost transparent when it is first brewed, with a light yellow glowing green, looking bright and fresh, but as the wine age increases, the color of dry white will gradually deepen and turn yellow, but the green will gradually disappear. The white wine fermented and cultivated in oak barrels is oxidized and absorbs tannins in a small part of the barrel. The color is always darker than the wine made in stainless steel barrels, and it often shows a golden tone when young.
What can you see through color?
1. It can determine the difference between warm and cool production areas!
2. Analyze the different years!
3. Determine the quality of the best and the second!
4. See if there are any signs of aging!
5. Is the wine spoiled?
