early grapes

Researchers in Australia say they have pinpointed key factors in the early ripening of grapes, providing potential answers for wine growers threatened by global warming.

A team led by Leanne Webb at the CSIRO looked at 10 sites in southern Australia where there were highly-detailed records, stretching from 1985 to 2009, for all of these factors.

The most common driver of earlier ripening was higher temperature, deemed a significant factor at seven sites.
