One of the six taste sens ations (besides bitter, fatty, sour, sweet, umami) that is mainly perceived in the front edge of the tongue. However, this taste sensation is also dependent on the wine temperature and is intensified at low temperatures.

Salts in grapes and wine

In the grape and later in the wine produced from it, the minerals are predominantly present as salts of organic acids. The most common organic acids of these salts are tartrate (tartaric acid), malate (malic acid), lactate (lactic acid), succinate (succinic acid) and citrate (citric acid). The organic acids are formed by the grapevine itself or are produced by yeasts or bacteria during fermentation and subsequent maturation of the wine. The concentration of these salty-tasting substances in the wine can vary greatly. It is usually 2 to 5 g/l of inorganic minerals and with a wide range of 5 to 20 g/l of organic acids, as salts together 7 to 25 g/l.
