The tannins in the wine provide interesting nutritional and medicinal properties in the wine glass. Find out what tannins are and what their most important virtues are.
The tannins are completely natural organic substances found in certain foods and beverages. Among the foods with the highest tannin content we can distinguish grapes, spinach or quince. While among the most important drinks we can highlight red wine and tea.
They tend to add nuance or a different flavor to the food or drinks where they are found. For example, in the case of red wine, tannins provide a sensation of dryness, astringency and roughness.
Although these substances are found naturally in the aforementioned foods and beverages, it is possible to obtain them from the maceration of the seeds. Or, in the case of wine, the skins (or, what is the same, the most of the wine).
The tannins of the wine.
The wine’s tannins have several important functions, especially in its different organoleptic properties (taste, texture, smell and color).
For example, when we taste wine, tannins are responsible for it being more or less dry, harsh and also has a certain astringency. While, in terms of color, they are combined with substances such as anthocyanins, acting in such a way that the color of the wine is much more stable, providing the characteristic red color and bluish tones to the wines.
Depending on the time of maturation and long fermentation in wood, the tannins can increase their presence

The grape is one of the richest fruits in tannins. We find them especially in their skin, seeds and scrape.
Its content also depends on the type of grape. Thus, for example, varieties such as the Syrah grape or the Cabernet Sauvignon grape stand out, which stand out for their thicker skin.
