grapes in Margaret River mature early

………………………………….

Predicted rising temperatures in the Margaret River region in the next few years are expected to have a significant impact on the quality of wine grapes, with early maturity an increasing concern.

Curtin University associate professor Mark Gibberd said a new study of WA’s wine regions showed a “demonstrable” change in grape maturation. AHA Viticulture senior consultant Jim Campbell-Clause said rising temperatures for the past eight years had made earlier vintages “pretty well the norm”. The trend is a warming trend, he said.
