Spain’s wineries produced 29.4 million hectoliters in the campaign’s first two months, up 26%

Spain’s wineries produced nearly 29.4 million hectoliters of wine in August and September, the first two months of the 2026/27 wine campaign, a 26% increase from the same period a year earlier, according to data published on Tuesday, November 3, by the Wine Sector Market Information System, known as INFOVI.

The total covers wine made in wineries through September and excludes must. In volume terms, the gain was about 6.1 million hectoliters compared with the opening two months of the 2025/26 campaign.

The September figure by itself was lower than the cumulative increase might suggest. Wineries produced 18.7 million hectoliters in September, slightly less than in September 2025, the data showed. By difference, August production was about 10.7 million hectoliters, based on the rounded totals reported for the two-month period.

That split helps explain why the monthly and cumulative comparisons point in different directions. September output alone eased from a year earlier, but a larger volume had already entered wineries before the month ended. As a result, the campaign reached the end of September with a much higher accumulated production level than at the same stage of the previous season.

The figures underline the effect that the timing of the grape harvest can have on monthly production readings. When the harvest starts earlier, more wine can be produced and recorded in August, changing the comparison for September without necessarily altering the broader picture for the start of the campaign.

For that reason, the 26% increase should not be read as a forecast for the whole 2026/27 season. The INFOVI data describe how much wine had been produced by the end of September, not how the full campaign will end once all regions complete processing and later monthly reports are added.

Spain is one of the world’s largest wine producers, and early campaign data are closely watched because they give the first official picture of how much wine is reaching cellars after the harvest begins. The latest numbers suggest that wineries entered the fall with substantially more wine already produced than they had at the same point in the previous campaign, even though the pace in September itself was slightly softer.

The contrast is important for reading the market. A lower September figure on its own could suggest weaker production, but the cumulative total shows that wineries were ahead of last year after two months. That difference comes from the earlier arrival of grapes and the resulting shift in production into August.

INFOVI is the official market information system for Spain’s wine sector, and the release published on Tuesday, November 3, reflects data closed through September. The report therefore captures only the opening stage of the 2026/27 campaign, when harvest timing can have a strong effect on month-to-month comparisons.
