With the irrigation restrictions I am curious how the vines will get water? Grapes need 8 to 10 gallons a week per vine via UC extension. Some of that comes from rain, but 18 inches a year is not enough. I couldn't make it work in socal(I used to live in Van Nuys). I moved to the Willamette valley in Oregon, now we get about 50 inches a year. Tablas creek(Tablas Creek Vineyard Blog) in Paso Robles does dry farming, but they get about the same rain(although not the same distribution) as Burgundy.
