Abstract
the article discusses core and additional characteristics of sparkling wines obtained
from wine materials produced using on-skins fermentation from ‘Cabernet-Sauvignon’
grapes grown in various microzones of Crimea. distinctive characteristics of sparkling
wines have been revealed (redox potential and active acidity values, mass concentration of aldehydes and amine nitrogen, percentage of monomeric and polymer
forms of phenolic substances from the sum of phenolic substances, intensity and
color tone), based on which the samples were divided into two groups depending
on their origin: group 1 - Yalta: Vasilyevka, Gurzuf; 2 group - Bakhchisarai region:
Vilino, Plodovoye villages. the obtained data can be used as additional indicators to
characterize sparkling wines produced from wine materials made from grapes grown
in various microzones of Crimea.
