•  “A real paradigm shift in our understanding of grape and wine production”

Terroir — the name given to the unique blend of a vineyard’s soils, water and climate — sculpts the flavor and quality of wine. Now a new study led by UC Davis researchers offers evidence that grapes and the wines they produce are also the product of an unseen but fairly predictable microbial terroir, itself shaped by the climate and geography of the region, vineyard — and even individual vine.

Results from DNA sequencing reveal that there are patterns in the fungal and bacterial communities that inhabit the surface of wine grapes, and these patterns are influenced by vineyard environmental conditions, the university says Monday.

The findings appear online this week in the Early Edition of the Proceedings of the National Academy of Sciences.
