Determination of biochemical characteristics of Kapistoni and Vermentino wines.
2023
Wine is a product of complex composition, which is obtained by the technological processing of grapes. More than 1000 components have been discovered and studied in it, most of which are characterized by beneficial properties for the human body. The composition of wine is greatly influenced by various factors, such as grape variety, winemaking technology, soil composition, fertilizers and pesticides, and various environmental and climatic factors. Kapistoni and Vermentino were selected for research from numerous varieties grown at the trial-demonstration research base of Jighaura. Dry white wines were produced using a similar technology. Based on the objectives of the research, the main chemical indicators - ethyl alcohol, pH, titratable acidity, volatile acidity, free SO2, bound SO2, and sugars - were determined in wines. Based on the results of the research, it was found that the wines selected for analysis correspond to the limits established by the standard for the main chemical indicators. Tab. 1, Ref. 5.
