A strong increase in world wine production is expected with a surge of 12% to 282 million hectoliters (mhl) year on year, according to the OIV, the International Organisation for Vine & Wine, after a historic low in 2017 due to adverse weather conditions. This is one of the highest outputs in recent decades and will correspond to around 376 million standard bottles of wine. Falling prices for bulk wine are already reflecting this abundance in supply.
The three biggest wine producing countries saw very large grape harvests: Italy (48.5 mhl, +14%), France (46.4 mhl, +27%) and Spain (40.9 mhl, +26%). Other than Greece and Portugal, all European wine-producing countries recorded high, often above-average harvests. It has been also one of the earliest harvest seasons on record (and the earliest ever in Germany).
Production levels in the United States (23.9 mhl) have remained stable for the last three years, while South America registered significant increases (+23% in Argentina and 36% in Chile). New Zealand had another strong harvest, but both Australian and South African wine production declined compared to 2017.
Significant harvest variation has been a reality of agricultural life for millennia, but there is increasing consensus that the large fluctuations and increasingly earlier harvest dates observed in the last years are linked to weather patterns affected by climate change.
