Argentina’s Grape Harvest Begins With Hopes for Higher Yields Despite Uncertain Projections

As the 2026 grape harvest begins in Argentina’s main wine-producing regions, the event is once again shaping the economic and social landscape for thousands of families. In provinces like Mendoza, San Juan, La Rioja, and Salta, the harvest is not just an agricultural milestone but a crucial period that reflects the well-being of local communities. This year, expectations are mixed. There is cautious optimism about a possible increase in grape yields, but concerns remain about climate unpredictability and economic pressures.

Data from the National Institute of Viticulture (INV) suggest that the volume of grapes harvested could rise by 5% to 10% compared to last year. However, these projections are uncertain. Daniel Romero, press secretary for FOEVA, points out that systematic vineyard surveys used to estimate production have been discontinued. “Today, there is no accurate projection because systematic surveys of vineyards, which were used to estimate production volume, have been discontinued,” he says. The harvest has only just begun for white grapes, and conditions could change quickly.

Weather remains a major factor. In 2025, heat waves in Mendoza and San Juan led to early ripening of grapes. At the same time, hailstorms and pests reduced yields significantly. “The weather is an unpredictable enemy,” Romero says. “Part of the harvest was lost and there wasn’t even enough to make must. The plant is increasingly exposed to these blows.” Each province faces its own challenges during harvest season, but most see stable or slightly declining production overall.

Despite new wine-growing areas emerging in Argentina, Mendoza and San Juan continue to be the main centers of activity. These regions face ongoing challenges that threaten their long-term stability. Economically, the grape harvest is vital for Mendoza in particular. It provides seasonal employment and is deeply tied to local identity. But this year’s outlook is complicated by falling domestic wine consumption and declining exports. “The drop in domestic consumption and the decline in exports have us on alert,” Romero says.

Three main issues are shaping this year’s harvest for local economies. First is the shift in rural employment as technology becomes more common in vineyards. Mechanization is reducing traditional jobs for manual laborers. “The activity is becoming much more technical, and that means that human labor is less in demand,” Romero explains. High taxes are also pushing some companies to import technological solutions from countries like Chile.

Second are wage negotiations between workers and employers, which become especially tense during harvest season. Wages are set through national collective bargaining agreements but often adjusted locally at the vineyard level. Unions play an active role in ensuring fair conditions for workers.

Finally, climate change continues to threaten grape production with increased risks from pests and diseases. The vine has historically been a resilient plant but now faces greater vulnerability due to changing weather patterns and environmental stressors. “It is noble, but today it is more vulnerable,” Romero warns.

The grape harvest remains a key indicator of economic and social health in Argentina’s wine regions. It generates thousands of jobs and brings labor issues into focus as wage negotiations coincide with peak activity in the fields. For many families in Mendoza, San Juan, La Rioja, and Salta, the outcome of this year’s harvest will determine their financial stability for months to come. As each season brings new challenges—from unpredictable weather to shifting market demands—the pulse of the harvest continues to measure not only agricultural success but also the resilience of entire communities dependent on wine production.
