Historical Winegrape Production Statistics

The accompanying charts show the historical wine grape production statistics for San Luis Obispo and Santa Barbara Counties, through 2019. The data values come from the Agricultural Commissioner’s Crop Reports for each county. San Luis Obispo County wine grape records begin in 1969, and Santa Barbara County in 1973; any existing acreages prior to these years were likely considered to be too small to report as separate crops.

The crop reports are available at the following links:
Some of these charts include inflation-adjusted dollar amounts, in which dollar values from earlier years have been expressed in October 2020 dollars; the inflation adjuster is from the US Dept. of Labor.
The Excel files that contain the raw data used in the charts are also available for download:
