Supergrapes could make good wine despite climate change

Experts say “terroir” — the geography, geology and climate of grapes’ native soils — defines the difference between good vintage and bad. But the plants’ sensitivity to their environment also means that climate change presents a massive threat to the industry and that delicate balance. However, new genetic research may stave off those worries, even as the planet warms.

Working with Corvina grapes, a team of Italian geneticists identified genes that help protect the fruit from the vagaries of the weather and could serve as a platform “for breeding new cultivars with improved adaptation to the environment,” the team reports Friday in the journal Genome Biology.
