(Coetzee and Adelsheim, 2016)įinally, there are mechanical improvements growers can make to their process to mitigate rising temperatures and improve productive yield. In recent times, harvesting is starting earlier…in 2007 the harvest began on January 23 in 2010, on January 21 and in 2015, on January 7”. Vriesenhof Vineyards, a local competitor, has also shifted its production schedule: “usual to start the harvest around February 5. The length of the production time is adapted to get the right quality. ![]() GUILD SOMM AUSTRALIA WINE MAPS FULLSome competitors in other Southern hemisphere countries, such as in Chile, are picking their grapes a full month earlier than traditional seasons. Potential improvements – rotating supply schedules/mechanical upgradesĪnother potential solution to deal with projected temperature increases is altering the supply chain timing – rotating the growing and picking season. GUILD SOMM AUSTRALIA WINE MAPS UPDATENederburg has had to update their sales strategy and attract different end consumers and distributors for their updated products. Nederburg’s long term change in grape choice impacts Nederburg’s entire business model given demand depends on carefully curated wine tastes. From these, Nederburg developed an Italian blend that was the first of its kind to be launched in the Western Cape. ![]() Both Tempranillo and Graciano (exhibit 1) were planted in 2004, and Nederburg previously introduced Italian varietals such as Sangiovese, Nebbiolo and Barbera. In the short term, Nederburg’s viticulturist, Bennie Liebenberg, highlighted that the winery has been experimenting with more traditional Mediterranean grapes suited to warming temperatures for more than a decade. GUILD SOMM AUSTRALIA WINE MAPS SERIESPathways to Just Digital Future Watch this tech inequality series featuring scholars, practitioners, & activists These grapes are run in smaller batches concurrently with the traditional grape crops, to observe their comparative yield and ripening time. Nederburg is running tests with these unusual grape varieties, experimenting and planning for future vintages. ![]() and Australia, for its ability to withstand extreme weather conditions – important for dealing with extreme variance in the medium to long term. Chambourcin is a well-known hybrid in the U.S. European and American species), and have the potential to be more robust – one of the most successful hybrids has been the Vidal Blanc, a grape which is resistant to cold weather and is used in Canada to make ice wine.

The UN Panel on Climate Change projects a 2C warming scenario, while researchers at the World Bank have modeled for a 4C increase – changes that will have a drastic impact on types of grapes grown worldwide (Gledhill, Hamza-Goodacre and Low, 2013) Further, climate can dictate taste cool climate grapes produce wines with lower alcohol and a lighter body, while hotter climates tend to produce bolder wines with higher alcohol. Growing seasons average approximately 170-190 days, and the specificity in climate and geographic traits required (exhibit 1) means that wine grapes are more susceptible to climate variability and long-term climate change than other commodities. Optimists have pointed out that the exciting possibilities of wine from northern regions (who’s ready for Scandinavian wine!), but for grape varieties central to regional industry and culture, changing temperatures could mean entire wine growing regions becoming obsolete.Īverage temperature and growing season length directly influence grape ripening and fruit quality. However, global warming looms large, threatening to redraw the global supply map. The Spanish proverb sums up the world’s love affair with wine – an industry forecasted to reach more than 30 billion liters by 2020 (TechNavio, 2016).
