Last week the University of California at Davis announced its latest research into terroir, that elusive concept that says wine profoundly reflects the place where the grapes it's made from grew. And now we're all trying to figure out what it means. So, I should add, are the scientists who did the study.
Prof. David Mills analyzed the mix of fungi and bacteria in crushed grapes from widely spread vineyards in Napa, Sonoma and Central Coast. By sequencing genes in 273 different lots over two vintages, he and his colleagues found that the microbe communities fell into distinct and predictable patterns depending on their location and grape variety. Intriguingly, the communities in Sonoma looked very different from those in Napa, and Sonoma showed more similarities to Central Coast than it did to Napa.
The big question is what this means for wine.
