Wildfires burning outside Bordeaux are underscoring the climate challenges facing France's largest wine region, where producers are grappling with severe drought, rising temperatures and falling wine consumption. In the vineyards of Margaux, one of Bordeaux's most prestigious appellations, the vines remain intact and wine quality is not expected to suffer from the fires, said Thomas Duroux, director general of Chateau Palmer. France's scorching summer has worsened drought conditions, strained water supplies and left vegetation tinder-dry, fuelling wildfires and threatening crops across the country. ADVERTISEMENTYoung vines, whose roots are not yet deep enough to reach underground moisture, have been the first to suffer. The Bordeaux fine wine market has lost nearly a fifth of its value over the past five years, according to the Liv-ex Bordeaux 500 Index.
