The Peggy J comment is interesting because normally I find I am in disagreement with her.
Both she and Eric criticize the fact that the grapes aren't on the winery site. I too, think that that wineries should have estate sourced grapes as a condition of approval, but there is apparently nothing in the WDO that requires it. Two tourist wineries have been built recently on Soda Canyon Road on 10 acre sites with no grapes, no residences and difficult winding uphill access driveways. This is not agriculture - just another tourist 'experience' in the remote areas of the county.
