ORGANIC ACIDS IN MUST AND WINE FROM GRAPES OF PERVENETS MAGARACHA VARIETY DEPENDING ON AGRONOMIC PRACTICES

Abstract

The influence of shoots load on the qualitative and quantitative composition of organic acids of musts and wines made from Pervenets Magara-cha grapes was studied. The research of influ-ence of agrotechnical measures was carried out on must and wine materials, on the following variants of experiment: load of 30 shoots / shrub; 35 shoots / shrub; 40 shoots / shrub; 45 shoots/shrub. It was revealed that the composi-tion of organic acids in grapes and wine to a greater extent depends on the varietal features of grapes and conditions of the year of harvest, while a clear dependence of the composition of organic acids on the load of bushes with shoots for the variety Pervenets Magaracha as a result of these studies could not be established.
