California's grape acreage totalled 897,000 acres in 2016
The major source of the grape detailed data was a questionnaire mailed to all grape growers from a database. The mailing was sent in late October 2016 to approximately 9,100 grape growers. The questionnaire contained previously reported crop, variety, and acreage information preprinted.
To arrive at the estimated grape acreage, the grape acreage data base was compared with data provided from the pesticide application data maintained by County Agricultural Commissioners and the Department of Pesticide Regulation.
