Study the phenol index in red grapes introduced in Georgia.
2018
The article provides an index of phenolic maturity in red grape varieties introduced in Georgia. In addition to determining the sugar/acidity index of red grape varieties for the beginning of vintage, modern winemaker countries measure the phenolic maturity index. The phenolic maturity index quantitatively shows the maximum number of phenolic compounds accumulated in the berries at the last stage of the ripening. The dynamics of the change of phenolic compounds in the introduced eight red grape varieties available at the Georgian agriculture collection base were studied. For each grape variety, the phenolic maturity index was determined, which allows conclude that the use of these introduced varieties are recommended to produce high-quality red wines.
