New wine better than vintage

The quality of the world’s wines has improved over the past 50 years because of global warming, research suggests.

But the future of Chianti, Rioja and Australian wines could be threatened as temperatures continue to rise.

A study of the 27 major grape-producing regions found wines from the 1990s and early 21st century were better and more consistent than in the 1950s. While improved viniculture techniques can explain some improvements, an average two degrees centigrade rise in temperatures has played a crucial role.

The study suggests England could become a significant wine-producing country as temperatures continue to rise over the next century, while Champagnes and Rhine Valley wines could also get better.
