Greek wine output will climb modestly in the 2026/2027 season despite punishing summer heat that scorched vineyards across southern Europe. Data from the Central Cooperative Union of Vine and Wine Products (KEOSOE) puts the projected harvest at 1.67 million hectolitres, a 1.2% gain over the prior season.
The figures, drawn from European Commission estimates, represent roughly 20,000 additional hectolitres compared to the 1.65 million recorded previously. Meanwhile, total EU wine production looks set to hold steady near 139.2 million hectolitres.
That stability masks sharp regional contrasts. Italy remains the bloc’s top producer at an estimated 41.12 million hectolitres, though that marks a 7.6% drop from 2025 levels. Spain follows with a Commission forecast of 37.6 million hectolitres, while France expects 33.86 million. German production could climb to 8.03 million, Portugal to 6.67 million, and Romania might surge 32.5% to 4.57 million.
Hungary and Austria face steep declines. KEOSOE projects Hungarian output falling 42% to 1.75 million hectolitres and Austrian production dropping 32% to 1.74 million.
Extreme heat accelerated grape ripening. Harvest crews in Italy’s Veneto region started eight to ten days early, while Spanish pickers began in late July, roughly two weeks ahead of schedule. One broker called the timing unprecedented. Quality assessments across Europe nonetheless remain positive.
Rising inventories present a separate challenge. Italian wine stocks reached approximately 41 million hectolitres by late September 2026, up 14% year over year. White wine reserves grew especially fast, with PDO stocks climbing 23.7% and PGI stocks jumping 34%.
Spain reported similar pressure. Combined wine and must stocks hit 40.1 million hectolitres, a 21.9% increase from the previous year. As a result, market watchers warn that swelling supplies in Italy and Spain could depress prices across the continent, even as Greek producers enjoy modest gains.
