In concentrations, higher than 5.2 g/L in wine it can contribute to the “sweetness” of a wine. Wine yeasts produce between 5 – 14 g/L in dry wines. It is not possible for the human palate to distinguish between glycerol concentrations in this range. A concentration of 25.8 g/L of glycerol is needed to influence the viscosity of a wine and so accurate measurement is important for winemakers.
