Abstract
Recent work has shown that sulfide appears to interact more strongly with copper (Cu) in wine than other likely copper-complexing species [1-2]. In low oxygen conditions during bottle aging, the total copper concentration in wine has been linked to increases in the hydrogen sulfide concentration, as well as other volatile sulfur compounds, a process contributing to the reductive development of wine [3]. A portion of the hydrogen sulfide that accumulates in wine during reductive aging has been attributed to release sulfide from sulfide-bound Cu in low oxygen conditions although to date, the exact mechanisms of release remain to be established [3-4].
This study investigated removal of sulfide-bound Cu from red and white wines by different membrane filter media and the influence of wine matrix on sulfide-bound Cu filterability.
