Greek 2026 Wine Harvest Brings Higher Output but Sharper Grape-Price Pressure
Greece’s 2026 grape harvest is producing sharply different regional outcomes, from severe losses in Santorini and Nemea to recovering volumes in Boeotia. High wine inventories and weak demand are pushing grape prices lower across several mainland regions.
Inventories weigh on the 2026 harvest
Greece’s 2026 wine-grape harvest has begun against weak conditions in the European and global wine markets, with large winery inventories and lower demand putting pressure on grower prices. Representatives of wine cooperatives belonging to KEOSEO reviewed conditions across the country at a meeting on 2 September 2026, according to Gargalianoi Online.
The pressure is especially visible in mainland production areas where crops are recovering. In Boeotia, grape output is expected to increase by 20–25%, returning to normal regional levels. Contract prices for Savatiano are set to fall to €0.30 per kilogram, while prices for other varieties are reportedly heading below €0.25 per kilogram. Comparable prices last year were €0.45–€0.48 per kilogram.
Mainland regions face falling prices and weather damage
Achaia expects production near the upper end of its normal range, but opening prices have fallen sharply. Muscat of Rio grapes are being paid at €0.40–€0.45 per kilogram, down from €0.70–€0.75 last year. Mavrodaphne and Roditis are expected to follow the same direction, with Roditis reportedly starting at €0.25 per kilogram versus €0.45–€0.50 previously. Local wineries cite high stocks as the reason for weaker purchasing conditions.
In Amyntaio and Naousa, production is expected to rise despite hail and difficulties controlling powdery mildew. Stocks and reduced demand, particularly weaker sales through restaurants, are weighing on prices even in protected designation of origin zones. Nemea faces a different production problem: frost affected 11,000 of its 25,000 stremmas, with losses estimated at 50–100%. At the same time, local wineries hold substantial wine inventories. Low-priced imported red wine at €0.60 per litre and white wine at €0.50 per litre add further pressure.
Island markets diverge sharply
Santorini remains the most constrained region. Grape volumes have fallen by 88% from 2022, the last year described as having normal production, and the 2026 crop is expected to decline another 35% from last year. Assyrtiko prices are again starting from €10 per kilogram, with limited supplies expected to attract competitive bidding. The shortage threatens wineries that rely solely on island-grown grapes for wines carrying the Santorini designation.
Conditions are more favorable elsewhere. Samos expects production to rise by about 10%, with prices at €0.80 per kilogram. Paros anticipates normal volume and quality after spring rain and a mild summer; Monemvasia is priced at €2.50 per kilogram and Mandilaria at €2.20 because of stronger demand. Rhodes reports higher output, better quality and stable prices of €0.60 per kilogram. Lemnos expects a good but slightly smaller crop after warm August winds, while its cooperative plans another modest price increase. Crete, by contrast, has suffered major vineyard damage from hail and downy mildew.
