Researchers map out world's winegrape varieties

University of Adelaide researchers have compiled statistics from 44 countries to develop the first database of the
world’s winegrape varieties and regions.

The new database funded by the Grape and Wine Research and Development Corporation (GWRDC) provides
an in-depth analysis of the world’s wine varieties and winegrape growing nations that account for 99 per cent of global wine production.

University of Adelaide School of Economics Professor Kym Anderson said a database of this nature has been
highly sought by the wine industry.

"In the wake of wine’s globalisation, wine producers need to exploit their geographical and varietal distinctiveness
in order to boost their competitiveness. This database, for the first time, offers transparency across the world’s
wine varieties and regions," he said.

This detailed database also uncovers more about changing trends in wine consumer behaviour.

"The database reveals that 20 years ago Airen, a white winegrape variety from Spain, was the most widely grown
globally, but now Cabernet Sauvignon is the world’s most grown winegrape," Anderson said.

"In 2000, white winegrapes were more widely grown; however, in the decade to 2010 red winegrapes increased
their share of the global vine-bearing area from 49 to 55 per cent.

"This is consistent with what we know about changes in wine consumption, with numerous countries moving away
from white and consumption rising in recent years in China where red wine is preferred."

Wine growers can also use this database to adapt to climate change.

"Wine producers are well aware of the impact climate change is having on their winegrapes. They’re continually on the lookout for attractive varieties that perform well in climates similar to what they expect theirs to become in the decades ahead."

GWRDC executive director Dr Stuart Thomson said this database is an exciting new tool for Australian wine

"GWRDC is pleased to have teamed with the University of Adelaide to build and implement this exciting new tool to
further support a competitive Australian wine sector," Thomson said.
