Grapes are the #1 agricultural crop in California.
That would be almonds. There are 1.3 million acres of almonds in the state. Grapes come in second with 844,000 acres. In 2021, California’s grape acreage declined slightly, while nut crops—almonds, walnuts, and pistachios—all saw acreage increases. For as delicious and nutritious as nuts are, there’s a big downside here. Unlike grapes, nut crops require copious amounts of water. It’s nuts that the state now in a mega drought (defined as a drought that lasts for decades) continues to promote water-guzzling crops.
