Definizione

Reddish-brown precipitate that develops in white wines. 1.

Nota

Exclusive to white wines, copper casse occurs after prolonged storage in the bottle, and requires the presence of proteins, which act as flocculants for the negatively charged colloids formed by the copper. […]
Formation of the precipitate, which has a complex chemical composition, occurs in wines with a total concentration of copper ions that exceeds 0.5 mg/L, and the risk increases at higher concentrations of copper, higher temperatures, and in the presence of light.
2.

Contesto

In addition, polyphenols act as buffering agents against the reduction reactions necessary for copper casse to occur. 2.
