Grapevine epiphytic microbiome (leaves,fruits)

Vine microbiome interacts with soil type, local environmental conditions, cultivars and agricultural practices, all together contributing to the establishment of vine terroir, a proof of quality and geographical identity of the produced wines. Today we know little about the composition of the vine microbiome in local Greek varieties and the factors shaping its composition. In this frame we asked the following questions (a) which factors shape the composition of the vine microbiome and how these operate at different geographical scales (viticultural zone vs nation level) (b) which is the composition of the vine microbiome in these Greek varieties. To provide answer, we collected grape and leaf samples at harvest (year 2019 and 2020) from four Greek cultivars Vidiano, Agiorgitiko, Roditis and Sideritis at different geographic scales.
