Oenological potential of local and new selection grape varieties

Abstract

Currently, in the Republic of Moldova the assortment of red wine grape varieties is dominated by the classic French varieties. In recent decades, however, there has been a growing interest in red wines produced from local varieties. This research shows the oenological potential of the local red wine grape varieties Negru de Causeni and Copceac and the new selection variety Codrinschii, while the local grape variety Feteasca Neagra was selected as a control one. The dynamics of the maceration-fermentation process and the accumulation of the phenolic complex and the oenological potential of the produced dry red wines were studied. Physical-chemical indices of the experimental red wines were identified, including organic acids, phenolic complex, and monomeric anthocyanins content. The research allowed to establish the prospect of producing dry red wines rich in phenolic and coloring substances from Copceac and Codrinschii grape varieties.
