calcium tartrate

Lemma: calcium tartrate
Etichetta di dominio: EN
Etichetta grammaticale: C.N.
Definizione: Crystalline salt that forms in wine. (1)
Nota: Some everyday wines produced in large quantities contain enough calcium to cause precipitation of calcium tartrate during bottle ageing, although this was most common in the era of the concrete tank. When the concrete tanks were new, or had had their protective coating of tartrates remove, wine dissolved enough calcium carbonate form the concrete surface to cause subsequent calcium tartrate instability. Stainless steel tanks, or lined concrete ones, have overcome the problem of calcium tartrate instability. (2)
Contesto: Calcium tartrate is NOT responsive to tempera¬ture like potassium bitartrate is. (3)
