Identification of the Varietal and Regional Origin of Red Wines by Classification Analysis

Abstract

We examined 144 samples of red dry wines of varieties Cabernet and Merlot, produced in the territory of the main wine-making enterprises of the geographical zones of Krasnodar krai, to consider the possibility of determining the regional and varietal identity of red wines. The concentration of micro- and macroelements in the wines was determined by inductively coupled plasma atomic emission spectrometry. Chemometric studies were performed in the Statistica package environment, using discriminant analysis and classification trees. Adequate mathematical models were proposed for wines to identify the grape variety and the region where it grows. A software product was developed that automates the necessary calculations.
