The object of the study is the production technology of high-quality Cahors wines. Although a number of studies have been conducted on the production of Cahors wines, the factors affecting the composition and quality of the wine material-particularly the regime of thermal treatment of the mash, as well as the type of alcohol and the method of fortification and their influence on the physicochemical composition of Cahors wine material-have not been sufficiently studied.
The total content of phenolic compounds in the control sample produced by the white winemaking method was 980 mg/dm3, whereas it reached 2740 mg/dm3 in the red winemaking method, 3230 mg/dm3 during thermovinification, and 3860 mg/dm3 in the Kurdamir method. A similar pattern, with some exceptions, was observed for color compounds. Relatively prolonged thermal treatment (4 hours) resulted in a pronounced caramelized note in taste and was evaluated 0.2 points lower than the preceding variant. In terms of quality, the second variant subjected to thermal treatment at 65°C for 3 hours performed better, receiving a score of 8.7 points. According to the results of organoleptic analysis, samples fortified with wheat alcohol were rated 0.9–1.6 points higher than the others.
Determining the effects of technological methods on the composition and quality of Cahors wine material samples, the duration of CO2 maceration, and the changes in physicochemical composition caused by thermal treatment, as well as the correct selection and use of alcohol for Cahors wines, is of practical importance for production. The results obtained can be applied in wineries and wine-producing enterprises
