Aim of this study is to analyse the microbiological composition of grapes and soil from a home vineyard located in Rzeszów.During the research, the following tasks were undertaken: determination of the total number of microorganisms, isolation of themicrobial cultures from grapes and soil, and identification of the bacterial strains and yeast using the MALDI-TOF MS Biotyper massspectrometry. Natural microbiota of grapes and soil are very diverse. Microbiological analysis showed that the total number ofmicroorganisms is higher in the soil, compared to grapes. As the result of the analysis of the microbiota of the home vineyard usingthe MALDI-TOF MS Biotyper mass spectrometry, five species of yeasts and eight species of bacteria were identified. Microbiologicalevaluation of the tested vineyard showed the presence of the yeast strains as Saccharomyces spp., Dekkera anomala, andCandida spp., and the strains of bacteria as Lactobacillus spp., Pantoea agglomerans, Lactococcus spp., Staphylococcus warneri,and Acetobacter spp.
