Abstract
Five types of red wine produced from the grape varieties from the Metohia
region (vintage 2014) were characterized on the basis of their chromatic
properties. The properties of bottled wines: Merlot, Vranac, Prokupac,
Cabernet and Game were analyzed. Chromatic characteristics of these wines
were observed four times during the year - spectrophotometer measurements
were performed on wines aged 0, 4, 8 and 12 months. Intensity, hue and
brilliance of color of these wines were determined (by the usual method of
Glories). The amount of coloring matter was determined by the usual method of
Durmishidze and the percentage of polymeric anthocyanins was calculated as
well. Wine ageing decreased the color intensity while the color hue value
increased. It was also found that contribution of wine color red pigment
decreased with wine ageing, while the percentage of yellow pigment in wine
increased. The total amount of colored substances in wines studied decreased
with wine ageing, while the percentage of polymeric pigments in wine
increased. This study presents the methodology for analyses of the chromatic
characteristics, and explains the origin influence of wine on these
properties. On the basis of these correlations the quality of red wine can be
established.
