Spain’s wine sector entered the spring with lower production, smaller stocks and weaker exports, according to data from the Interprofessional Wine Organization of Spain, known as OIVE, based on the INFOVI registry for March 2026.
The organization said total wine production in the first eight months of the 2025/26 campaign reached 28.9 million hectoliters, down 7.1% from the same period a year earlier. Must production fell even more sharply, dropping 27.3% to 4.2 million hectoliters. Combined wine and must output stood at 33 million hectoliters, a decline of 10.3%.
March itself was a very quiet month for production, with just 3,631 hectoliters of wine recorded. OIVE said the figures include producers that make fewer than 1,000 hectoliters a year, whose output was reported separately in the expanded November 2025 declaration.
By color, among producers with more than 1,000 hectoliters of output, white wines accounted for 16.2 million hectoliters, down 9.4%, while red and rosé wines totaled 12 million hectoliters, down 4.7%. Producers below the 1,000-hectoliter threshold increased output by 12.1% to 610,555 hectoliters.
Castile-La Mancha remained by far the largest producing region, accounting for 56% of recorded wine production in the first eight months of the campaign and 85% of must output.
The expanded March data also broke production down by product type. Of the 28.2 million hectoliters produced by larger wineries, 10.4 million hectoliters were wines with protected designation of origin, or DOP; 9.5 million hectoliters were varietal wines; 5.5 million hectoliters were wines without any geographic or quality indication; and 2.9 million hectoliters were wines with protected geographical indication, or IGP.
