Tannin is a tanning substance. It is an odorless phenolic compound that has a bitter taste. The name tannins combines substances that have different compositions but common properties.
These are the tart taste, the ability to fix with proteins without dissolving them, and the ability to create a dark blue color in combination with iron salts.
Tannins are found in many plants, especially oak and chestnut. Grapes contain tannin, which is found in the skin of the berries and in their seeds.
Grape tannins are condensed tannins that are formed by the polymerization of several molecules. During the maturation of the wine, changes in the degree of condensation affect the color of the tannins.
There should be no tannin in white wines, and tannins are a desirable element in red wines, as they give the wine the ability to age and have a richer taste.
The tannins of the grapes enhance the color of the red wine and participate in the formation of the taste of the wine, giving it fullness and special tartness.
Tannin is also important for the production of whiskey, cognac, brandy and other beverages, which receive from it preservative properties and certain taste characteristics.
Saturation with tannins helps for faster and more active digestion of food. Tannins help digest meat, so for centuries meat has been served with wine.
Tannins are found in apple cider, beer, coffee beans, guarana, rosehip tea, black and red beans, cinnamon, oregano, cumin, vanilla.
Some fruits contain tannins - these are apricots, cherries, nectarines and peaches, pomegranate, blueberries, strawberries.
