Effectiveness of carboxymethyl cellulose (CMC) on tartaric stabilization of cava base wine
Abstract
Recent EU regulations allow the use of carboxymethylcellulose (CMC) as a stabilization agent in wine. We tested CMC in bases for sparkling wines, which must be stabilized before the second fermentation that raises alcohol concentration by 1,5%. Our results show that CMC was able to stabilize wine against potassium bitartrate precipitation even when alcohol concentration was increased. stability was controlled by the Boulton’s test and by analyzing conductivity at -2°C. However if the wine was not completely stable the addition of CMC caused the appearance of a filamentous precipitate.
