Wine-Searcher reports that climate change is forcing Sancerre producers to reconsider how they preserve the appellation’s identity as warmer and more erratic conditions alter ripening patterns. The article highlights shrinking picking windows, rising alcohol levels, falling acidity, mildew pressure, soil and exposure differences, higher trellising and cover-crop decisions, showing how growers are trying to keep Sancerre focused on terroir rather than simply producing warmer-climate Sauvignon Blanc.
