Climate change is posing a severe threat to Prosecco, according to recent research published in the iScience journal. Originating from Italy’s mountainous vineyards, Prosecco has seen a decline in grape yields due to extreme weather conditions and soil degradation. The risk extends beyond losing an agricultural product as it also threatens entire communities’ history and cultural roots.
Extreme weather events, including sudden, intense rainfall and droughts, are making it increasingly difficult for Prosecco producers. These conditions lead to soil erosion and slope failures in the steep vineyards of Northern Italy. This year, the vineyards experienced massive spring rainfall and hailstones, followed by an extremely hot summer. Such unstable weather could reduce Italian wine grape harvests by up to a fifth.
Prosecco’s distinct flavour is attributed to its high-altitude origin. These mountain-grown grapes are smaller and have a higher ratio of skin to juice, resulting in an intense flavour. The practice of growing grapes on steep slopes is termed ‘heroic viticulture’ due to the challenges it presents, including a serious workforce shortage in the mountains.
It’s not just Prosecco that’s under threat as other European wines like Burgundy, Grand Cru and Cabernet Sauvignon are also at risk.
