Temporal and spatial analyses of temperature in a French wine‐producing area: the Loire Valley

A significant warming trend has been observed across the Loire Valley, a renowned French wine-producing region, with temperature increases recorded at all regional weather stations over the past 60 years. This study highlights that spatial variability in temperature and bioclimatic indices is more pronounced at local scales, particularly within vineyards, compared to broader regional patterns. Using a multi-scalar approach, researchers analyzed data from Météo-France's network and high-resolution temperature loggers placed within vine rows, including those in the sweet wine-producing Coteaux du Layon appellation. The findings underscore the complex interplay between climate change and viticulture, suggesting that microclimatic variations could significantly impact wine quality and vine phenology.
