California Grape Acreage Report, 2002 Crop
Released:    June 3, 2003



SURVEY METHODS

The California Agricultural Statistics Service (CASS) annually conducts an acreage survey of California grape growers. This is a continuation of a long series of annual surveys to provide grape acreage by variety and year planted.

Users are cautioned that this report consists of two parts:

*   Estimated grape acreage -- bearing, non-bearing, and total.

*   Detailed data by variety, year planted, and county -- as voluntarily reported
     by grape growers and maintained in CASS's data base.

With perfect information, the estimated grape acreage and the detailed data would be equivalent. However, this will never be the case for the following reasons:

*   A voluntary census of approximately 10,000 grape growers is unlikely to ever
     attain 100 percent completeness.

*   It is extremely difficult for a small staff in Sacramento to detect growers that are
     planting grapes for the first time.

*   The detailed data reflects vine removals from more than 37,000 acres during the
     past twelve months. Of this number, significant acreage was harvested in 2002
     prior to being pulled out, and that acreage has already been removed from the detailed data.

The major source of the grape detailed data was a questionnaire mailed to all grape growers included in CASS's data base. The mailing was made in late December 2002 to approximately 10,000 grape growers. The questionnaire contained previously reported crop, variety, and acreage information preprinted. Producers were asked to update the information with new plantings, removals, and any other corrections; new growers were mailed a blank questionnaire. Growers were given six weeks to respond by mail. A telephone follow-up was then undertaken. Field personnel personally visited large growers who did not respond by mail or telephone.

To arrive at the estimated grape acreage, the CASS 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.


DATA CLARIFICATIONS

Bearing and Non-bearing Acreage: For purposes of this publication, all varieties are considered non-bearing for three years ( i.e., acres planted in 2000 would not be bearing until 2003). The only exceptions are the Thompson Seedless variety and all table type grapes in Imperial and Riverside counties, which are of bearing age after one year.

Grafting: Graftings on bearing acres are recorded as planted in the previous year ( i.e., Chardonnay grafted in 2002 onto a 1979 variety is recorded as planted in 2001). This assumes that grafted vines will actually bear a full crop in two years as opposed to three years for a newly planted vine.

Varieties: Data are provided for each variety with 50 or more total acres standing in 2002. Acreage for all other varieties are combined in "Other" categories. Care was taken to properly identify each block reported with a recognized varietal name.

Rootstock: Most of the rootstock shown was planted in the past three years. However, some earlier plantings are included. When rootstock was budded over, the year of planting assigned to that block of grapes was the year preceding the budding. For instance, if a 2000 rootstock planting was budded over in 2002, the year of planting assigned to the selected variety was 2001. (See Grafting.) Nursery rootstock is not included.

Period Covered: The primary intent of the 2002 survey was to record removals of grapes since the 2001 harvest and new planting of grapes during 2002. Acreage abandoned in 2002 was excluded from bearing acreage. Planting activity is accounted for on a calendar-year basis.

Grape Crush Districts: Grape acreage data is also being published by grape crush districts (Table 10). A map with descriptions of those districts is located on the inside front cover.


RESULTS

California's 2002 grape acreage is estimated by the California Agricultural Statistics Service (CASS) at 932,000 acres. Of the total acres, 847,000 were bearing and 85,000 were non-bearing. The breakdown by type is as follows: Raisin type totaled 279,000 acres with 273,000 bearing and 6,000 non-bearing; Table type totaled 97,000 acres with 88,000 bearing and 9,000 non-bearing; Wine type totaled 556,000 acres with 486,000 bearing and 70,000 non-bearing.

Varieties are not published for raisin type grapes because no industry funding was received. However, the Thompson Seedless continues to be the leading variety and is used for raisins, fresh market, concentrate and wine.

ACKNOWLEDGMENTS

We sincerely thank the many farm operators, owners, and management firms providing the information. Funding was provided by an assessment on wine grapes plus funding from the California Table Grape Commission. The raisin industry did not fund the acreage survey this year so the raisin variety data are not included in this report.

Several County Agricultural Commissioners provided a significant number of individual grower changes. We would particularly acknowledge the work of the Merced, Napa, and Sonoma county staff.

A special thanks is due the following office staff for the hundreds of hours spent on this project: Kelly Albelo, Pamela Benner, Regina Claypoole, Pearl Gonzalez, Ann Jehn, Janell McAllister, Lupe Moreno, Jeremiah Rhine, and Sheryl Zazzi.
