Wine production in Portugal declined significantly in 2025, reflecting the combined impact of adverse weather conditions and growing international trade uncertainty.
Data from the National Institute of Statistics (INE) and statements from the Portuguese Wine and Spirits Association (ACIBEV) confirm a challenging year for the sector, particularly for smaller winegrowers with limited technical and financial resources.
According to ACIBEV, the 2025 harvest registered a 14% decrease compared to 2024 and a 16% drop versus the average of the past five years. Ana Isabel Alves, executive director of ACIBEV, attributes this contraction primarily to climatic instability, which increased production costs and reduced yields across most wine regions.
A Difficult Agricultural Year
The 2025 agricultural cycle proved demanding from the outset. Persistent spring rainfall combined with mild temperatures created ideal conditions for vine diseases, particularly downy mildew, forcing winegrowers to carry out repeated phytosanitary treatments. These interventions significantly raised production costs and placed additional pressure on smaller producers, many of whom struggled to apply all necessary measures in time.
The situation worsened during the summer months, when high temperatures and prolonged drought led to sunburn and dehydration of the grapes. These conditions reduced berry weight and directly impacted overall production volumes. While larger wineries were better equipped to manage these challenges, smaller operations experienced disproportionate losses.
Lower Volumes, High Quality
Despite the reduced quantities, both ACIBEV and major producers report very good grape and wine quality in 2025. INE forecasts point to wines with balanced sugar levels and strong aromatic concentration, suggesting promising results in the bottle.
Sogrape, one of Portugal’s leading wine groups, confirmed a decline in harvested volumes, with variations depending on region and grape variety. However, the company considers the impact manageable due to its diversified sourcing strategy, inventory management, and broad portfolio spanning multiple brands and export markets.
Casa Santos Lima also reported lower production compared to 2024 but emphasized the excellent quality of the grapes. The winery indicated it has sufficient reserves to meet market demand, mitigating short-term supply risks.
Inventory Adjustment and Price Implications
The reduction in production may influence price dynamics. According to Ana Isabel Alves, a decrease in output of 10% to 20% could help reduce accumulated inventories ahead of the 2025 harvest, potentially contributing to price stabilization. However, she cautioned that relying on production cuts as a balancing mechanism is structurally unfair and places undue strain on winegrowers.
Export Challenges and Global Competition
Beyond domestic factors, international trade conditions further complicated the outlook for Portuguese wine in 2025. ACIBEV noted that exports were negatively affected by uncertainty surrounding US tariff policy. Importers hesitated to place orders due to the risk of tariff changes occurring while shipments were en route to the United States.
Portuguese wines also face intensified competition from producers in Argentina, Australia, Chile, and New Zealand, which currently benefit from lower tariffs when entering the US market. Sogrape highlighted that the 15% tariff imposed on European wines has generated significant uncertainty, adding to pressures already present since the pandemic.
Strategic Responses and Outlook for 2026
In response to these challenges, wineries are increasingly focusing on innovation and market diversification. Casa Santos Lima, for example, continues to develop wines tailored to different price segments and consumer preferences, while expanding into new export destinations.
Looking ahead, ACIBEV expects overall sales to remain stable, supported by the EU–Mercosur trade agreement and the potential approval of a future trade deal with India. Nevertheless, both Sogrape and Casa Santos Lima approach 2026 with caution, anticipating intensified competition and persistent uncertainty in both domestic and international markets.
While 2025 may be remembered as a year of lower volumes, it also underscores the resilience of Portugal’s wine sector—one capable of maintaining quality standards and adapting strategically in the face of climatic and geopolitical pressures.
