Calcium tartrate, exactly calcium L-tartrate, is a byproduct of the wine industry, prepared from wine fermentation dregs. [ 1 ] [ 2 ] [ 3 ] It is the calcium salt of L - tartaric acid , an acid most commonly found in grapes . [ 4 ]
In contrast to tartaric acid, if the grapes are too acidic, calcium carbonate is used to bring them down to the level needed to make wine. [10] In addition, many also use oak, oak slices, fermentation agents, tutu, and more, according to the quality of grapes and the different styles of wine.

A bunch of Cabernet Sauvignon wine grapes at varying levels of ripeness. Ripening is a process in fruits that causes them to become more palatable. In general, fruit becomes sweeter, less green, and softer as it ripens. Even though the acidity of fruit increases as it ripens, the higher acidity level does not make the fruit seem tarter.
Malic and tartaric acid are the primary acids in wine grapes. The acids in wine are an important component in both winemaking and the finished product of wine. They are present in both grapes and wine, having direct influences on the color, balance and taste of the wine as well as the growth and vitality of yeast during fermentation and protecting the wine from bacteria.
Bowen also predicts that other natural options may become more popular, including minerals such as calcium carbonate (white) and iron oxides (red, brown and black), fruit and vegetable extracts ...
