Research of anthocyanins in red special wine "Nikala"

The article describes red special wines, surrounded by anthocyanins of grape skins and polyphenols from pits. The particular interest of consumers in red natural and special wines is growing daily due to their high content of bioflavonoids. The aim of our study was to study the anthocyanin glycosides of the special “Nikala” wine, made from the colour grape raw materials “Otshanuri Safere”, cultivated in the viticulture micro zone in the Imereti region. Red special wine contains anthocyanins 410.87 mg/dm3, of which 72.13% are aminoglycosides, where the highest amount is Malvidin 41.04%. The special wine contains 13.40% of the glycoside forms of anthocyanins, i.e. 64.37 mg/dm3. From the study of anthocyanins, it can be seen that in a special wine from the “Otskhanuri Safere” Malvidin glycoside is 2.26%, i.e. 9.05 mg/dm3.
