Historical Winegrape Production Statistics
The accompanying graphs show the historical winegrape production statistics for San Luis Obispo and Santa Barbara Counties, through 2015. The data values come from the Agricultural Commissioner’s Crop Reports for each county. San Luis Obispo County winegrape 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.
These graphs will be updated annually when the most recent crop reports become available for each county. These 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 2015 dollars; the inflation adjuster is from the US Dept. of Labor.
