Within just the last six weeks I’ve experienced global warming up close and personal: 92-degree late-May weather in Burgundy, 102 degrees in Walla Walla before the end of June, and the steam heat of a New York City summer. But somehow Mendoza, Argentina’s engine of wine production, a semi-arid desert region that could not produce wine without irrigation from melting Andes snow, has not had a classically warm, dry growing season since 2012 – until this year, that is.
