Adieu, Bordeaux? Frances’ wine-producing areas may dry up by 2050 – study
A warming climate threatens drastic declines for wineries in the
Bordeaux and Rhone regions in France, Tuscany in Italy as well as
beyond the Mediterranean, in Napa Valley in California and Chile,
according to the study published in the American ‘Proceedings of
the National Academy of Sciences’.
It requires cool winters and hot dry summers to produce good
grapes. However, researchers expect big changes in regions with
A warming climate will make it harder to grow grapes in
traditional wine regions.
Hence, nearly three quarters of the world's wine-producing
regions might become unsuitable, the report predicts.
The sharpest decline is expected in Europe, where the scientists
predict an 85 percent decrease in production in Bordeaux, Rhone and
As the average temperature increases by between 2.5 and 4.7° C,
“Southern France will see a lot of declining suitability,”
Lee Hannah, the leading author of the study, told AFP.
The future is also predicted to be less bright for Australian
wine growers, with a 74 percent drop, and California’s, with a 70
Wine growers in the Cape area of South Africa would also be hit
hard, with a 55 per cent decline. Chile's wine producers would
expect losses of about 40 percent, the study found out.
"I think wine lovers will find their wines will come from
unusual areas, and the varieties they're used to getting from
places like France will be changing," Hannah says.
"Enthusiasts will have to begin thinking about wine in a
However, he stresses the study does not suggest the end of wine,
but drinkers might soon be surprised at bottle labels.
“Redistribution in wine production may occur within
continents, moving from declining traditional wine-growing regions
to areas of novel suitability,” the authors wrote. “At
higher latitudes and elevations, areas not currently suitable for
viticulture are projected to become more suitable.”
The climate change may open up other parts of the world to
grapes, as producers may start looking for higher, cooler
The study predicts traditional France and Italy regions could
give way to wilderness areas around Yellowstone Park, or the hills
of Central China becoming prime areas for wine production.
“Global changes in suitability for wine production caused by
climate change may result in substantial economic and conservation
consequences,” predicts the report.
According to the International Organisation of Vine and Wine,
global wine production dropped 6 percent in 2012, the lowest level
in at least 37 years, on smaller grape crops in France, Spain and
