The microbiota reveals different physiological characteristics and depends on the grape ripening stage and the availability of nutrients with different effect on wine production. The microbiota of grape berries (n = 12) was isolated and identified in the present study. The samples were collected in September 2018. Grape berries were obtained from Vrbovo vineyard located in Slovakia. The grape berries investigated belonged to Blue Frankish, Cabernet Sauvignon, Chardonnay, Dornfelder, Feteasca regala, Green <em>Veltliner, </em>Irsai Oliver, Mūller Thurgau, Pálava, Pinot Blanc, Rhinriesling and Welschriesling varieties. The microorganisms were cultivated on Malt extract agar (MEA) at 25 °C for five days in aerobically for microscopic filamentous fungi and Tryptone Soya agar (TSA) at 37 °C for 24 – 48 h aerobically for bacteria and yeasts. Total bacterial counts on different wine grape berries ranged from 2.57 ±0.09 in Chardonnay to 4.39 ±0.21 log CFU.g<sup>-1</sup> in Pálava. Microscopic filamentous fungi count ranged from 1.18 ±0.03 in Blue Frankish to 2.60 ±0.17 log CFU.g<sup>-1</sup> in Welschriesling. MALDI-TOF MS Biotyper mass spectrometry was used for identification of microorganisms (bacteria and yeasts) and microscopic filamentous fungi with manuals. The most identified microscopic fungal species was <em>Alternaria</em> sp., for yeasts <em>Issatchenkia orientalis </em>and <em>Leuconostoc mesenteroides </em>subsp. <em>mesenteroides</em> for bacteria<em>.</em></p>}, number={1}, journal={Potravinarstvo Slovak Journal of Food Sciences}, author={Kačániová, Miroslava and Kunova, Simona and Felsöciová, Soňa and Ivanišová, Eva and Kántor, Attila and Puchalski, Czeslaw and Terentjeva, Margarita}, year={2019}, month={Mar.}, pages={174–181} }
