Heatwaves Are Transforming Our Food: From Stronger Champagne to Bitter Lettuce
Discover how heatwaves are altering food production, from bitter lettuce to stronger champagne and arsenic-laden rice.
POLICY WIRE — Paris, France — This summer’s extreme heat has begun to reshape the way we grow and consume food, with effects ranging from stronger champagne to more bitter greens. As global temperatures rise, agricultural practices and food quality are being redefined in ways that may soon become the new normal.
France, long known for its strict food regulations, has had to make some unusual adjustments. The 2026 Champagne vintage will feature a higher alcohol content, up to 15%, due to rapid grape ripening caused by prolonged heat. Industry leaders warn that this shift could signal a long-term trend as climate conditions continue to evolve.

Heat is not just affecting wine. Droughts have forced temporary changes to cheese production rules, including reduced grazing time for cows. Lettuce, under stress, tends to bolt and become bitter, while tomatoes can fail to ripen properly. In the UK, early harvests and reduced yields have already impacted wheat production, and rising temperatures may increase arsenic levels in rice. These changes are not just about availability—they are altering the very nature of what we eat.
