That the climate has turned unfavourable for the Australian wine regions and is not likely to turn favourable in near future is something which is haunting the Australian wine grapes growers for long. If one is to go by the wildfires due to dry spells, rise in temperature extremities, irratic rainfall, and the reducing yields of berries, the conclusion is unmistakeable. On the financial side of the wines business in Australia, the unpredictable weather is casting its shadow on wines sales and revenue earnings.
The trends of changing weather have been forecasted by CSIRO which has clearly stated that in next 15 years, the temperatures will rise 0.3 degree Celsius to 1.5 degree Celsius. This will mean more dry spells and more raging wildfires, which are already affecting Australian wine growth. Temperature plays a major role during the ripening period of the grapes. It has to be just the right temperature. Being either too hot or too cold would result in change in sugar content and flavouring compounds.
Well, so much so for the adverse impacts. What is the solution? Many wine growers have already began looking for the new vistas for viticulture. This include exploring new cooler regions for the growth of wines. Whether moving up on altitude or latitude, possibilities are being explored to find cooler and suitable climes.
Besides looking for the new regions, technological intervention in farm practices are also being explored. These include developing sturdier varieties of fruit using modern farming bio-technologies. A fresh look is also being given to how the vineyards are managed in order to mitigate the effects of climate change.
So, while the threat from climate change is real, a range of solutions are being implemented to prevent the adverse impact on Australian wines.
