A study into the impact of climate change on wine grape production has found increased levels of carbon dioxide cause wine grapes to ripen earlier.

The wine industry is investigating how climate change will impact grape production by exposing vines in north-west Victoria to the temperature and carbon dioxide levels predicted by 2050.

Research scientist Rachel Kilmister said an extra two degrees and 200 parts per million of carbon dioxide was having a noticeable impact on the vines and the taste of the wine produced.

"What we are seeing at the moment is that we get earlier ripening from increased temperature, which means we have earlier harvest dates," she said. ... es/6975444
