Development of the production technology of divine "Succes" from new selection and local varieties

Abstract

The researches were carried out within the IP Scientific-Practical Institute of Horticulture and Food Technologies, during the years 2018-2023. The grapes of new selection (LuminiTa, Alb de OniTcani, Distil) and local (PlAvaie, Zghihara de HuSi) varieties were harvested from the institute's plantations and processed in the microvinification section. The Aligote grape variety served as a control. The physic-chemical indices of the obtained wines and distillates were determined according to the standardized methods and the OIV methods (including using gas chromatography method). The distillations of the raw material wines were carried out at the distillation installation with periodic direct distillation operation. The raw material wines obtained from the researched varieties were physic- chemically analyzed and then distilled. The obtained results demonstrate that all young wine distillates, according to the physic-chemical indicators, fall within the requirements of the SM-312 norms. The wine distillates were aged on Moldavian oak wood under laboratory conditions. After 4 years, a blend obtained from distillates of new selection and local varieties of 4-year-old was prepared. As a result of the research carried out, the Technological Instruction for the manufacture of divine “Succes” of 4-year-old (IT MD 67-40582515-133: 2023) was developed.
