California Growers Unveil Most Accurate Vineyard Acreage Map to Date
Dear Vintners and Growers:
Today, a longstanding project we have engaged in with the California Association of Winegrape Growers (CAWG) was released.
ARTICLE
The California Association of Winegrape Growers (CAWG), in partnership with regional grower and vintner associations, has released the results of the 2025 California Winegrape Vineyard Mapping Project, providing the most accurate, field-verified accounting of California’s vineyard acreage to date.
The analysis identified 477,475 acres of standing winegrape vineyards as of August 2025, and 38,134 acres removed between October 2024 and August 2025.
Conducted by Land IQ, a Sacramento-based agricultural and environmental science firm, the project delivers a comprehensive spatial mapping of vineyard blocks statewide, along with data summaries detailing standing and removed acreage by county, crush district, and American Viticultural Area (AVA). The mapping system uses advanced remote sensing, artificial intelligence, and on-the-ground field verification to achieve vineyard-level precision. Read the rest of the article here.

METHODOLOGIES AND CORRECTIONS
We are aware of the discrepancy between the 2024 Annual Crop Report and the newly released mapping project. We are currently reviewing the differences between the acreage figures historically reported through the NASS Grape Acreage Report and the new data provided through the California Vineyard Mapping Project. The two datasets use different methodologies, and capture information at different times: NASS relies on survey-based reporting, with estimates, while the mapping project uses field-verified, block-level analysis of what is physically in the ground.
Please review your vineyard(s) for accuracy. If you discover that your vineyard is not accurately mapped, please complete the attached Discrepancy Form. As growers in all regions begin reviewing the interactive map, we expect to identify and clarify any errors that may exist.
SEMINARS FOR QUESTIONS
CAWG will be hosting two webinars with Land IQ, the firm that led the mapping project . All industry is welcome to attend to learn more about the project, functionality of the mapping tool, and ask any questions you may have. Here are the dates/times/registration links:
