Chromatographic analysis of wine fermentation products using an Aminex® HPX-87C column and a RI detector provide a fast and accurate technique for quantitatively determining ethanol and glycerol. The RI detector detects fermenting carbohydrates, glycerol and alcohol that may be present in the wine. As an example, the figure below presents a typical sugar profile for a cabernet sauvignon wine, obtained with the Aminex HPX-87C column and a RI detector.
