Google Books’ website contains a treasure trove of information pertaining to California’s prior wine production statistics, the quantities of grape varieties grown in each region, etc, only if one knows precisely how to find it. Otherwise, the attempt can prove to be a rather disheartening!
The publication shown below names most counties’ major grape growers, and identifies the varieties cultivated by each.
If only this information was still made publibly available on an annual basis.

In 2017, a TTB document asserted, “Rose of Peru is a red Vitis vinifera variety, long grown in California, that DNA evidence has disclosed to be identical to the Mission variety…”.
