Very limited thinking here. Wine sales are not the only use of grapes. Yes they are a different grape, but they are not the whole industry.
California produces nearly 99% of the table grapes and 100% of the raisins in the United States, centered primarily in the San Joaquin Valley around Fresno. I was born in Dinuba, my grandfather had a citris ranch, thompsons as part of it, and his grapes made into raisons were sold world wide by sunkist.
The U.S. table grape market is valued at approximately $4.08 billion annually, while the domestic crop value sits around $2.49 billion. The U.S. raisin industry generates roughly $300 million to $400 million annually in total production value. So griping about wine grapes is a little short sided.
California has enough trouble with water shortages and crops are dying anyway all over the state. Marketing is a mute point by pointing the thought on one piece of it.
