Climate change is leading to less and worse tasting sparkling wine

Climate change is driving global wine production to historic lows, with sparkling wine facing specific threats to its quantity and quality. Extreme weather in France, Spain, and Italy has led to reduced yields and price increases for labels like Cava and Prosecco. Higher temperatures are accelerating ripening, which alters the balance of sugar and acid, potentially resulting in higher alcohol levels and less fizzy wines. Projections suggest that if global temperatures rise by 2°C, over half of suitable wine-growing regions could shrink, with up to 90% of traditional areas in southern Europe becoming economically unviable. Adaptation strategies, such as relocating vineyards or using protective technology, are costly and may fail to preserve the unique cultural and flavour characteristics of traditional sparkling wines.

• Global wine production reached a historic low in 2024, decreasing by 4.8% from 2023 and marking the lowest level in over 60 years. While sparkling wine exports grew significantly over 25 years, production quantity and value have declined slightly since a peak in 2021-2022.
• Climate-induced extreme weather has caused significant harvest losses and price spikes for specific sparkling wines. In Spain, 2023 droughts reduced harvests in some regions by over 45%, contributing to a 20% international price increase for Cava. France experienced its smallest Champagne harvest since 1957 in 2021, resulting in approximately USD 2 billion in lost sales.
• Rising temperatures are fundamentally altering the flavour and physical properties of sparkling wine. Heat accelerates ripening, which spikes sugar levels and breaks down acids, leading to wines that may be too alcoholic, lack acidity, or have 'cooked fruit notes' instead of fresh aromas. Higher alcohol levels can also reduce the amount of foam, making the wine less fizzy.
• Harvesting schedules have shifted significantly due to warming; wine-growing regions have seen nearly 100 additional days per season with temperatures over 10°C since 1980. In the Champagne region, harvests now occur 20 days earlier than they did 30 years ago, with August harvests occurring eight times since 2003.
• Global warming poses an existential threat to traditional viticulture. If temperatures rise 2°C above pre-industrial levels, the number of suitable wine-growing regions could shrink by more than half. In southern Europe—specifically coastal and low-lying areas of Italy, Spain, Greece, and southern California—up to 90% of traditional areas could become economically unviable by the end of the century.
• Climate change is increasing health and safety risks for agricultural workers. Higher temperatures lead to more intense labour demands and heat-related fatalities, such as the four grape harvesters who died in Champagne in 2023. Additionally, wildfire smoke in regions like Sonoma County, California, has caused short-term health impacts for over two-thirds of agricultural workers exposed to it.
• Adaptation measures are often prohibitively expensive or insufficient to preserve wine characteristics. Electric heating cables to protect against frost in France can cost EUR 100,000 per hectare. While relocating vineyards to higher latitudes (e.g., Germany and the UK) is an option, it risks losing the unique flavours and cultural heritage associated with traditional regions.
