The application and efficiency of each method were controlled through conductivity and pH and potassium and calcium levels. Results show that L(+)-CaT acts as an inductor of the KHT and CaT crystallization, while KHT seeding only induced KHT crystallization, and therefore, Ca levels in wine are not reduced. In another test, L(+)-tartaric acid (H2T) was added, leading to some inhibition in the CaT crystallization. ER -
