Extreme weather conditions are causing significant problems for wineries in Southern Europe, with the Assyrtiko grape variety, used for white wine, being severely impacted. Yields have dropped sharply due to intense heat, with some predictions suggesting the grape variety could disappear by 2040. This issue is part of a larger problem, with the International Organization of Vine and Wine (OIV) predicting a 10% global wine production drop in 2023, the lowest level in 60 years, due to adverse weather conditions including heavy rains, drought, and early frosts. In particular, production in Greece is expected to fall by over a third, while in Italy and Spain it is expected to fall by over a fifth.
