Wine Regions in a Changing Climate

Climate change is reshaping the wine map. Historically cool regions such as England and southern Sweden are now successfully experimenting with Pinot Noir and Chardonnay; Champagne harvests ever earlier and sees rising alcohol levels. In the Mediterranean region — southern Spain, Sicily — extreme summer heat and drought threaten traditional grape varieties. Growers respond by moving cultivation to higher altitudes, using thick-skinned varieties, or adapting pruning styles. Research from the climate institute INRAE in France shows that the harvest date in Bordeaux has shifted almost three weeks since 1980. These changes affect terroir, and with it the future credibility of appellations.
