MAREUIL-SUR-AY, FRANCE -- Champagne grape pickers have had to start the harvest earlier this year, as climate change forces the makers of the French sparkling wine to rethink how they make the coveted bubbly.
High temperatures and the worst drought on record have caused massive wildfires and led to restrictions on water usage across France. But they also boosted grape maturity.
An August harvest, rather than in early September last year, used to be a once in a lifetime experience in Champagne in the past, said Charles Philipponnat, president of the family-owned Philipponnat Champagne winery that produces several hundred thousand bottles a year. Not anymore.
"It's quite clear that global warming is having an effect now," he said in his winery in northern France.
Around him, pickers hired for the short harvesting season and paid on what they pick were rushing around in temperatures well above 30 degrees Celsius (86 degrees Fahrenheit) as the sun beat down on the steep hillside where the precious Pinot grape grows.
It is important to pick the grapes before they become over-ripe and supercharged with sugar.
"I think we're at the turning point," Philipponnat said. "So far, global warming has helped: harvest in good weather conditions without rain, without too much cold, with ripeness and little rot."
Producers across France are expecting this year's harvest to yield a good quality vintage when it makes its way to market, a relief after frost and mildew fungus attacks ravaged vineyards in 2021, something dry and hot weather helped prevent this year.
"What's coming now is possibly over-ripe grapes," Philipponnat said. "Possibly too dry summer seasons that will cause other problems, that we'll need to adapt to. We'll need to adapt our viticulture, and adapt our oenology – the way we make the wines."
One of the first steps has been picking the grapes earlier than in the past decades, and not just for Champagne.
Harvesting season this year was about two weeks early this year in most large wine regions of France - something likely to be a lasting trend, winemakers said.
"The wines may become different and we may have to adapt to other grape varieties or cultivation methods that are a little different from what we do now," said Laurent Pinson, Chablis wine producer in Burgundy, in central-eastern France.
While harvesting there used to take place around October in the 1980s, it progressively moved forward so much that harvesting early September is now the norm, with occasional cuttings in August, Pinson said.
