This area has a specific microflora composition which changes based on its climate dependence, as well as during the fermentation process of wine production. Therefore, the aim of this study was, by culture examination of the samples, to detect the microbiota of soil, leaves, berries and fermentation must from two vineyards from the Slovak part of Tokaj. The highest total viable count (5.60 ±0.01 log cfu.g<sup>-1</sup>) and the highest total yeast and mould count (4.32 ±0.01 log cfu.g<sup>-1</sup>) in soil samples were recorded in vineyard Berecký. The highest total viable count in soil samples (6.71 ±0.01 log cfu.g<sup>-1</sup>) was confirmed by examination of samples originating from the vineyard of Čierna Hora. When determining the total yeast and mould count, the highest numbers were recorded in the must samples (4.15 ±0.01 log cfu.mL<sup>-1</sup>). Lactic acid bacteria were collected in samples from both vineyards, only in very low numbers. Overall, statistically significant differences (<em>p</em> &lt;0.001) were detected by comparing the microbiota of the samples taken from the Berecký and Čierna Hora vineyards. The specific characterisation and identification of yeast was carried out using ITS-PCR-RFLP methods. The analysis confirmed the presence of yeasts of <em>Saccharomyces cerevisiae</em>, <em>Zygosaccharomyces bailii</em>, <em>Zygosaccharomyces rouxii</em>, <em>Candida parapsilosis</em> and <em>Candida tenuis</em> and their subsequent transfer to the must at varying percentages.</p> ER -
