The Fermentation of Fructose in Winemaking

Glucose 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

SO2 production by wine yeast during alcoholic fermentation

This issue of 'The Wine Expert' will discuss how sulphur dioxide is not only an exogenous compound, but is also produced by yeast during alcoholic fermentation.  An understanding of this is important to ensure successful MLF.

Glycerol and winemaking

Glycerol is a non-volatile compound which has no aromatic properties, but which significantly contributes to wine quality by providing sweetness and fullness.  This Issue of 'The Wine Expert' explores its properties and the ways to influence  its production.
