While there are substantial studies suggesting that characteristics of wine are related to regional microbial community composition (microbial terroir), there has been little discussion about what factors affect variation in regional microbial community composition. In this study, we compared the microbial community composition of leaves and berries of a grape variety (Carmenere) from six different Chilean vineyards within 35 km of each other. In order to determine relationships between spatial proximity and microbial compositional dissimilarity, we sequenced amplicons of the internal transcribed spacer (ITS) region for fungi and 16S rRNA gene for bacteria. Results showed that both the fungal and the bacterial community compositions of the studied vineyards differed, but this difference was much clearer in fungi than in bacteria. In addition, while bacterial community dissimilarity was not correlated with geographic distance, the leaf and berry fungal community dissimilarities between locations increased with geographic distance. This indicates that spatial processes play an important role in structuring the biogeographic pattern of grape-associated fungal communities at local scales, which might in turn contribute to the local identity of wine.
