The Fermentation of Fructose in WinemakingGlucose and fructose are the main fermentable sugars in wine must. During alcoholic fermentation, yeast convert most of the glucose and fructose present into alcohol and CO2. Saccharomyces cerevisiae is a glucophilic yeast, preferring glucose over fructose. This issue of ‘The WIne Expert’ further explains this phenomenon.Wine Expert- The Fermentation of Fructose in winemaking 2013

MLF Bacteria – Efficient Contributors to WinestyleThe effects of malolactic fermentation (MLF) on wine aroma and chemical properties of Australian Cabernet Sauvignon were explored at the AWRI , by inoculation with different selected Oenococcus oeni. Significant compositional differences occurred in response to the different MLF treatments and strain dependent changes in volatile aroma compounds were observed. Increases in fruity esters were associated […]

YSEO process: a unique yeast production processLallemand has developed a unique yeast production process called YSEO® (Yeast Security and Sensory Optimization). This process increases fermentation reliability and security and ensures fewer organoleptic deviations, but not all yeast can be prepared by this process. The process (when compared to non YSEO®): Improves the yeast cells assimilation of essential micronutrients and vitamins. Improves […]
