I bet they wouldn't. The early California vinters were mostly Italian. Ever hear of names like Mondavi, Martini, Sebastiani, Gallo, Nichelini, Simi, Parducci, Pedroncelli, Seghesio, Martinelli, Rafanelli, Riboli, Foppiano? There were a lot of Germans and other Europeans too, but the Italians dominated the California wine trade until relatively recently.
