Syrah production. This made Shiraz the most planted variety in Australia and Australia the world's second largest Syrah/Shiraz grower, after France.

Effects of climate change on wine production Effects of climate change on wine production Climate change in recent times has become a major issue and talking point globally because of its effects on the environment and the repercussions this could be having or possibly have. The effects of climate change on Viniculture (wine production) are described in this article. Grapevines ("Vitis vinifera") are very responsive to their surrounding environment with a seasonal variation in yield of 32.5%. Climate is one of the key controlling factors in grape and wine production, affecting the suitability of certain grape varieties to a particular region as well as the type and
