Abstract

The results of the technological evaluation of white technical forms and grapevine varieties, bred by ARRIV&W – branch FSBSI FRARC are presented: 11-17-4-7, 11-17-5-1, 11-18-5-8, 11-17-3-5, 11-17-1-2, 11-17-4-12, 11-17-4- pk, from which samples of natural dry white wines were made according to classical technology.
