New statewide analysis establishes 477,475 standing acres and 38,134 acres removed
November 4, 2025 (Sacramento, CA) — 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.
“This mapping gives us a new level of spatial accuracy, showing what’s actually planted and where,” said Natalie Collins, CAWG president. “It provides a shared, credible foundation for regional benchmarking, market planning, and informed policy – giving us a reliable baseline to understand change, promote transparency, and plan responsibly for the future.”
Project results will be available to CAWG members and partner-association members via secure login in two formats:
- Statewide report (PDF): Standing and removed acreage by county, crush district, and AVA. Page one of the report can be viewed here.
- Interactive mapping tool: A web application to explore vineyard plantings statewide.
