Erratic weather in Spain and Italy has led to smaller grape harvests, causing a drop in overall wine production in 2023, according to the International Organisation of Wine and Vine (OIV). However, there are some positive signs as the Burgundy trade organization, Vins de Bourgogne, reported a larger than expected harvest. The OIV warned that while countries like France, Germany, New Zealand, Portugal, and the US are expected to have above-average wine outputs, it may not be enough to offset the declines caused by extreme weather conditions in Argentina, Australia, Brazil, Chile, and South Africa.
