You may have heard the objective truth as proven by science that climate change poses an existential threat to the planet, and in the future it's going to hit humanity where it really hurts—the wine glass. Start stocking up your cellar for the end times, because a winepocalypse is nigh.
Wine producers in Western Europe—particularly France and Switzerland—are enduring droughts that actually contribute to a current Wine Boom. According to the Huffington Post, "Droughts are crucial in great wine." They "reduce surface moisture, dry the soil and bring on the harvest." But ever-increasing heat is unsustainable.
“So far, a good year is a hot year,” said Elizabeth Wolkovich, an ecologist at Harvard University. However, she continues, “If we keep pushing the heat up, vineyards can’t maintain that forever.”
Wolkovich and fellow ecologist Benjamin I. Cook studied 400 years of data from France and Switzerland, analyzing harvest times between 1600 and 2007 (woah). Cook notes that climate change is already affecting production, and could force wine growers to use different grape varieties. Cook wrote in The New Republic that with droughts forcing harvests to happen earlier, "There is likely a limit... to how much earlier the fruit can mature and the harvest occur and still have this translate to higher-quality wines."
