From the University of Adelaide:
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% of global wine production.
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,” Professor Anderson says.
“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%.
“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.”
