Abstract
Grapegrowers can be informed to upcoming heatwaves thanks to the Heatwave Service for Australia provided by the Bureau of meteorology. They also have tools to prepare for heatwaves with a number of mitigation options available. These include hydrocooling, canopy management, sunscreen or even shade clothe to reduce direct bunch exposure to sunlight during the summer months. However, with more open spring canopies, or early leaf removal used in some vineyards, young berries may be at risk with the increasing severity and frequency of extreme heat events early i the season. It is thus essential to understand the sole effect of high temperature on berry development, and compounds such as tannins whose biosynthesis start around flowering. In Addition, heatwaves occurring during berry ripening have worsened with berries exposed to air temperature up to 45oC, and reaching well above 50oC of unprotected due to canopy damage.
