Extreme Heat Pushes Italy’s 2026 Grape Harvest Ahead of Schedule

Italy’s 2026 grape harvest has started about 10 days earlier than usual as extreme heat speeds up ripening, adding new uncertainty to a season already shaped by drought, storm risk and weaker export demand.

Coldiretti, the Italian farmers’ association, said harvesting began in Oliva Gessi, in the Oltrepò Pavese area of Lombardy, at the Defilippi I Gessi winery, where growers are bringing in white grapes for sparkling wine. In that area, harvest work typically starts in the first part of August. This year, the earlier start reflects how sustained summer heat has pushed fruit to mature faster.

The shift is one of the clearest signs yet of how climate change is altering the rhythm of Italian viticulture. Growers are increasingly being forced to adjust vineyard management, labor planning and winery operations around hotter summers and less predictable weather. Coldiretti said this year’s harvest will likely stretch across nearly five months, making it especially hard to estimate final volumes at this stage.

The main question is yield. While high temperatures have accelerated ripening, drought remains a major unknown and could reduce production in some areas. At the same time, record heat and dry conditions are increasing sugar concentration in grapes, a factor that can affect alcohol levels and style in finished wines. For producers, that creates both an opportunity and a challenge as they try to preserve balance in the fruit while deciding when to pick.

For the beverage sector, the earlier harvest matters well beyond the vineyard. It can affect winery scheduling, tank space, grape purchasing decisions and staffing needs during a compressed period of activity. If drought cuts yields in some regions while sugar levels rise quickly, producers may also face changes in wine style, volume and release planning later in the year.

So far, Coldiretti said one threat appears to have eased: downy mildew risk is currently considered limited. The group said quality prospects look excellent in many parts of the country. But that outlook remains exposed to weather shocks during the harvest period.

Hail and unstable weather are still major concerns for the 2026 vintage. Coldiretti said hail has already hit vineyards in scattered areas from northern to central Italy, causing serious damage. That means growers are dealing with two opposing pressures at once: prolonged heat and dryness on one side, and sudden destructive storms on the other.

The unusual timing is not limited to northern Italy. In Tuscany, Coldiretti said Sangiovese grapes could begin to be picked around mid-August, an exceptionally early date for red wine grapes that are traditionally harvested between September and November. If that happens on a broad scale, it would mark a significant break from long-standing harvest patterns in one of Italy’s most important wine regions.

The agricultural group described 2026 as a particularly difficult year for forecasting because conditions vary sharply from place to place and because harvest timing may differ widely by grape variety and region. That uneven picture makes it harder for wineries, cooperatives and buyers to plan production with confidence.

The harvest is also opening against a difficult economic backdrop for Italian wine producers. Coldiretti said wineries are under pressure from bureaucracy, higher production costs linked to geopolitical tensions and changing consumer habits. According to its analysis, bureaucracy costs producers €1.6 billion a year. It also said wine stocks held in cellars were up 6.7% by volume from a year earlier.

Input costs have added further strain. Citing figures from Centro Studi Divulga, Coldiretti said the war involving Iran has added €250 per hectare in extra costs for each farm through higher prices for energy, fertilizers and materials. Those increases come at a time when many producers are already trying to manage tighter margins.

Trade has become another source of pressure. Coldiretti said Italian wine exports fell 7% by value in the first four months of 2026, with shipments to the United States down 15%, weighed by tariffs introduced under President Donald Trump. For wineries that depend on foreign markets, weaker exports add another layer of uncertainty just as the new vintage begins to arrive.

Labor remains a problem as well. Coldiretti said many companies continue to report difficulty finding specialized workers for harvest operations despite recent progress on labor flows and protections designed to address extreme heat conditions in the fields. An earlier harvest can intensify that challenge by forcing employers to secure crews sooner than expected.

Even with those pressures, wine remains one of the pillars of Italy’s farm economy. Coldiretti said the country has about 241,000 active wine businesses, annual turnover of roughly €14 billion and 681,000 hectares of vineyards. It added that 78% of vineyard area is dedicated to geographical indication wines, underscoring how closely production volume and quality are tied to regional identity.

Italy’s wine sector also depends heavily on its wide range of native grape varieties, which gives producers flexibility but also exposes them differently to heat, drought and storms depending on local conditions. That diversity may help some regions adapt better than others as climate patterns continue to shift.

For now, growers are entering harvest with cautious optimism about quality but little certainty about quantity. The season has started early, but much will depend on whether vineyards receive enough water, whether storms stay away and how quickly grapes continue to ripen through August and into the fall.
