Sažetak
The ratio of glycerol to D-gluconic acid indicates the "quality" of the rot, with high ratios for Noble Rot and lower ratios for Sour Rot. The aim of this work was to investigate dynamic of glycerol and D-gluconic acid content in wines from late harvest, selected harvest, berries selection, dry berry selection and ice wine of ten different cultivars. Total of 54 Croatian wines from late harvest (vintage 2005, 2006 and 2007) were investigated. Glycerol and D-gluconic acid content were measured enzymatically by spectrophotometry method. Glycerol content ranged from 4.3 g/L for late harvest wine to 23.1 g/L for dry berry selection wine. D-gluconic acid content range from 1.3 g/L for late harvest wine up to 8.2 g/L for dry berry selection wine. The most pronounced cultivar in glycerol and D-gluconic acid production was cv. Gewürtztraminer. Ratio of glycerol to D-gluconic acid fluctuated between harvests, cultivars and vintages and ranged from 2.7 to 15.4. Highest ration was found in cv. Chardonnay ice wine indicated dominant Noble Rot.
