The diploma thesis “Evaluation of acid changes in grapes and wines” is divided into theoretical and practical part. In the theoretical part were described individual acids, possibilities of their regulation in musts and wines and selected methods of their determination. In the practical part of diploma thesis, the parameters of the grapes (pH, total titratable acids, tartaric acid and malic acid) were observed during the ripening period. The varieties Müller Thurgau, Pálava, Frankovka and Svätovavrinecké were studied. Berries were taken at regular weekly intervals from 2.8. to 20.9. 2018. In the second part of the experimental part of the work, the wines were monitored in three stages of vinification. The pH, total titratable acid, tartaric, malic and lactic acid parameters were monitored. The results were interpreted using tables and graphs. Subsequently, they were statistically evaluated and described.
