Abstract:Grapevine cultivation at high altitudes provides a viable option for producing premium quality wines in the context of climate change. This is primarily attributed to cooler temperatures, wider thermal amplitudes, and increased UV-B radiation. Although high UV-B levels can cause oxidative-stress, grape berries acclimate by generating UV-blocking anthocyanins and antioxidant compounds accumulated in the berry skins, thereby enhancing the organoleptic qualities and aging capacity of wine. This UV-B exclusion stu… Show more
