Three commercial Saccharomyces cerevisiae yeast strains: Viniferm Revelación, Viniferm SV and Viniferm
PDM were evaluated for the production of pomegranate wine from a juice coupage of the two
well-known varieties Mollar and Wonderfull. Further malolactic fermentation was carried out spontaneously.
The same fermentation patterns were observed for pH, titratable acidity, density, sugar consumption,
and ethanol and glycerol production. Glucose was exhausted while fructose residues
remained at the end of alcoholic fermentation. A high ethanol concentration (10.91 ± 0.27% v/v) in combination
with 1.49 g/L glycerol was achieved. Citric acid concentration increased rapidly a 31.7%, malic
acid disappeared as result of malolactic fermentation and the lactic acid levels reached values between
0.40 and 0.96 g/L. The analysis of CIEa parameter and total anthocyanin content highlights a lower degradation
of monomeric anthocyanins during winemaking with Viniferm PDM yeast. The resulting wine
retains a 34.5% of total anthocyanin content of pomegranate juice blend.
