“In the memory of vignerons, there are two major freezes: 1991 and 1994. This is on the level of 1994. It’s historic,” said Guillaume Lapaque, director of the federation of the Indre-Loire wines trade group and the Bourgueil wine syndicate. “It froze on three nights–April 18, April 25 and then April 27.”
Temperatures dipped below freezing in several of France’s prized central wine regions this week, striking both Burgundy and the Loire Valley. In the Côte d’Or, Chablis to the north and Côte Chalonnaise, frost arrived early on the morning of April 25 and again the next night and the morning of April 27, resulting in frost that damaged the newly formed buds.
Farther west, central regions of the Loire Valley, including Chinon, Bourgueil and Vouvray, were similarly hit.
