WEDNESDAY, NOVEMBER 12, 2025. BY LODI WINEGRAPE COMMISSION.
The California Association of Winegrape Growers (CAWG), in partnership with regional grower and vintner associations including the Lodi Winegrape Commission, hired Land IQ to develop an in-season, statewide winegrape acreage assessment.
Acreage was assessed as of August 1, 2025.
Land IQ has been mapping vineyards for the California Department of Water Resources since 2014. This mapping effort differentiates winegrapes from the other vineyard crops which also includes table grapes and raisins. Land IQ draws upon on multiple lines of evidence including agronomic and remote sensing knowledge, unique field boundaries, robust on-the-ground verification, customized image analysis, artificial intelligence and machine learning algorithms to classify vineyards.
The acreage estimate takes into account standing winegrape vineyards between October 1, 2024 through August 1, 2025. Standing acreage reflects all vines physically in the ground, including bearing and non-bearing vineyards, as well as vineyards that have been mothballed or abandoned but not yet removed. Removed vineyards were also determined through spatial analysis for the same period.
The 2025 statewide acreage is:
477,475 acres of standing winegrapes
38,134 acres of removed winegrapes
The table below shows standing winegrape acreage and removals by California county as of August 1, 2025.
More detailed information is available to grower members of cooperating associations. If you are a Lodi Winegrape Commission assessment-paying grower (Crush District 11), you may contact Stuart Spencer to get more information. Our updated Lodi AVA standing winegrape acreage as of August 2025 is 82,303 acres, with Crush District 11 at 82,646 acres.
A second informational webinar on this mapping project will take place on November 20, 2025 at 10am PT. Click HERE to register. The first webinar recording is below.
This cooperative project was funded and supported by: CAWG, Allied Grape Growers; Clarksburg Winegrape Growers Association; Lake County Winegrape Commission; Livermore Valley Winegrowers Association; Lodi District Grape Growers Association; Lodi Winegrape Commission; Napa Valley Grapegrowers; Paso Robles Wine Country Alliance; Santa Barbara Vintners; Sonoma County Winegrape Commission; Suisun Valley Vintners & Growers Association; and Temecula Valley Winegrowers Association.
