| The 48-year-old winemaker explained that unlike his own nearby vines, which were old, with deep roots, these vines were unable to tap the earth’s underground reserves of water, leaving grapes vulnerable to this year’s drought and brutal summer sun. | The 48-year-old winemaker explained that unlike his own nearby vines, which were old, with deep roots, these vines were unable to tap the earth’s underground reserves of water, leaving grapes vulnerable to this year’s drought and brutal summer sun. |

| A 2016 study by NASA and Harvard of grape harvest dates going back to the 1600s found that climate change pushed harvests forward drastically in France and Switzerland in the second half of the 20th century. | |
| Other studies have suggested that traditional wine-growing regions in Europe and around the world will become too hot for the berries traditionally linked to their earth and climate, or terroir, and will be forced to adopt varietals built for heat. | Other studies have suggested that traditional wine-growing regions in Europe and around the world will become too hot for the berries traditionally linked to their earth and climate, or terroir, and will be forced to adopt varietals built for heat. |
| The vexing possibilities are worthy of contemplation over a fine wine: What is Bordeaux if it becomes inhospitable to cabernet franc or merlot? What is Burgundy without pinot noir? What if southern England supplants Champagne as a home to sparkling wine? | The vexing possibilities are worthy of contemplation over a fine wine: What is Bordeaux if it becomes inhospitable to cabernet franc or merlot?

| “It’s 20 days earlier on average due to climate change,” Ion Bruno, 50, a worker who has been picking the grapes for the last three decades, said as he clipped a stem. | |
| Drought, more than heat, threatens the grapes, he said, adding that instead of steady rainfall, precipitation now comes in downpours that run off the hillsides and do little to slake the thirst of the vines. | |
| “Decades ago there would be snow on the ground in November,” said his partner Bruno Novelli, 58, as they moved to a new vine. “And now it doesn’t snow anymore.” | “Decades ago there would be snow on the ground in November,” said his partner Bruno Novelli, 58, as they moved to a new vine. “And now it doesn’t snow anymore.” |

| His son, Maurizio, 37, also spoke of the benefits of the sunshine. But he added that temperatures above 100 degrees “are not good for the wine; the berries become unbalanced and too fat, with too high an alcohol content.” | |
| He said that they knew how to deal with anomalies, but that if intense heat waves became permanent, “We’ll have to plant bananas and pineapples.” | |
| That, of course, would be a tragedy to the world’s wine connoisseurs, who have come to worship this region’s Barolos and Barbarescos, nebbiolos and barberas. The wine has also been good to its best producers. | That, of course, would be a tragedy to the world’s wine connoisseurs, who have come to worship this region’s Barolos and Barbarescos, nebbiolos and barberas.
