Context and purpose of the study - Climate change is a major challenge in wine production. The IPCC (2014) projected that by the end of the 21 st century average temperatures will increase by 1-3.7°C. Consequently, harvest dates could advance by approximately 30 days. A general observed trend is the increase in berry sugar content and decrease in...
