French winemakers set candles and straw afire to save vines from frost
Temperatures plunged equally low as -5°C overnight in wine regions in Burgundy and Bordeaux, which could hurt shoots already well-adult because of earlier mild weather.

French winemakers have lit candles and burned bales of straw to attempt to protect their vineyards from sharp spring frosts, with the forecast of more cold nights this week raising fears of serious damage and lost production.
Temperatures plunged as low every bit -5°C overnight in wine regions including Chablis, in Burgundy, and Bordeaux, which could injure shoots already well-developed because of earlier mild atmospheric condition.
Outside Chablis, known around the world for its fruity, acidic white wine, a deep orange glow from tens of thousands of candles hung over the rolling vineyards in the early hours.
Winemaker Laurent Pinson said he had put between 300 and 600 large candles – burning cans of paraffin – across many of his 14 hectares of vines.
"The harvest is at pale over a few nights – i, two or three nights – and if we take no harvest, that means no sales, no vino for consumers," Pinson told Reuters.
Although it was still as well early to appraise the damage, producers said it was inevitable.
"Information technology will also be common cold overnight from today to tomorrow so there is a lot of worry," said Christophe Chateau, from the Bordeaux wine producers grouping CIVB. "With two nights in a row there is twice every bit much take a chance of the vineyard existence damaged."
Winemakers also put out smouldering harbinger bales to provide a smokescreen to prevent the early sun from burning frozen shoots; sprayed water over the vines with the aim that the ice that forms protects them from freezing; and installed heaters and wind towers that mix the cold air about the ground with warmer air above.
Spring cold snaps accept been happening before in the year, in April rather than early May around xx–25 years ago, meaning the fall in temperatures tin be greater, Pinson said.
"Then we are no longer on small bound frosts at -1°C/-two°C, we tin can come across frosts at -4°C, -v°C, -six°C or even more in some areas – information technology is very problematic because in terms of protection (of the vineyard) there is no longer the aforementioned efficiency at all," he said.
A severe cold spell in Apr 2022 damaged vineyards so much that annual French vino output was the lowest in history. Frosts had already caused harm the previous yr and again in 2019.
