Keywords: Climate change, viticulture, remote sensing, sustainability, Winkler Index
Climate is a primary determinant of viticultural potential, directly influencing grape phenology, yield, and wine style. In recent decades, climate change has introduced increasingly complex challenges for vineyard managers and the wine industry. The critical objective of modern wine growing is to maximize yield and minimize water consumption without compromising quality. This research aims to assess how viticultural climate classifications have changed over time and what these shifts imply for sustainable vineyard adaptation. Using time series analysis of historical climate records and remote sensing data, vineyard regions are classified annually based on the Winkler Index. The study identifies trends in heat accumulation, temporal shifts in viticultural zones, and evolving regional suitability for grape production. These findings offer insights into the long-term effects of climate change on viticulture and aim to support evidence-based adaptation strategies and business decisions for growers and winemakers.
