Wine lees and tartaric materials, by-products of the grape wine-making process, are, after distillation, treated to obtain calcium tartrate: this is the raw material from which natural tartaric acid is obtained.
The two calcium tartrate and tartaric acid production plants feature cutting-edge technology and a fully integrated computer control system.
Maximum daily output capacity is 25 tons of tartaric acid and nowadays it is the most sophisticated plant in the world.

A top quality fruit is at the base of the production process of the distillates, so that the Distillerie Mazzari S.p.A., are equipped by an efficient system of quality control of its raw materials and only the fruits that pass these tests can go to the next steps of the production process.
