RT info:eu-repo/semantics/article T1 Effect of different ageing techniques on the polysaccharide and phenolic composition and sensorial characteristics of Chardonnay white wines fermented with different selected Saccharomyces Cerevisiae yeast strains A1 Barrio Galán, Rubén del A1 Medel Marabolí, Marcela A1 Peña Neira, Álvaro K1 Polysaccharides · Phenolic compounds · White wines · Saccharomyces cerevisiae yeast strains · TDS sensory analysis AB Polysaccharides, mainly mannoproteins, play an important role on technological and sensory quality ofwines. These compounds are released to the wine during alcoholic fermentation and, thereafter, during yeast autolysis in the ageing process. The effect of the ageing on lees and other alternative ageing techniques were studied in Chardonnay Chilean white wines previously fermented with different Saccharomyces cerevisiae yeast strains (Zymaflore VL2 and Lalvin CY3079). The Lalvin CY3079released higher amounts during alcoholic fermentation and during the first stages of the ageing than the Zymaflore VL2, which could produce a positive effect on the colour intensity of wines. Some statistically significant differences on phenolic families and sensory attributes were observed after alcoholic fermentation, during the ageing period and bottle storage, but this depended on the yeast strain used,the ageing technique applied and the period of ageing and bottle storage analysed.
