This thesis deals with the content of biogenic amines in natural wines. It compares the results of the sensory evaluation of the analyzed samples with the results of the chemical analysis of the basic parameters of the wine and with the results of the analysis of the content of biogenic amines. In the literature review, the chemistry and toxicology of these substances is described. The biochemistry of processes and the conditions under which they originate are explained in detail. Part of the review deals with the technical process of detection of biogenic amines. The experimental part describes the material and methods of determination of the sensory and chemical parameters. Both analysis are compared and statistically processed. The results show that biogenic amines are formed primarily by lactic acid bacteria and are found to be present in larger amount in wines that have undergone spontaneous malolactic fermentation. Based on these conclusions the propositions for future research and its applications in process of winemaking is made.
