The aim of this study was to determine the influence of temperature during the second fermentation and aging of spar- kling wines (AOC Cava) on their foam properties. The results indicate that sparkling wines elaborated at 12 °C have a maximum height (HM) and a stable height (HS) of the foam significantly higher than the corresponding ones produced at 16 °C. This better foam properties observed in sparkling wines obtained at low temperature are probably related with their higher protein and oligosaccharide concentration.
