The History

In 1769, Spanish Franciscan missionaries planted the first citrus trees at Mission San Diego de Alcalá. They weren't thinking about juice. They wanted shade, scent, and vitamin C for sailors battling scurvy on the long Pacific crossings. They had no idea they were planting the seed of a billion-dollar industry.

The industry took shape in the 1870s when the transcontinental railroad made it possible to ship fresh oranges east. Suddenly an orange wasn't a luxury import. It was affordable, exotic, and distinctly Californian. Southern California marketed itself as the land of sunshine and health. The orange became its emblem.

The California Fruit Growers Exchange (later renamed Sunkist) was founded in 1893 as one of America's first agricultural cooperatives. Their innovations in branding, advertising, and cold-chain logistics turned a regional crop into a national commodity. The "Sunkist" stamp on an orange was one of the first recognizable food brands in American history.

By the mid-20th century, juice had overtaken fresh fruit as the primary use of California's Valencia crop. The post-war suburban boom turned OJ into a breakfast ritual. "A glass of sunshine" in every American kitchen. California growers leaned into the CDFA's quality codes and positioned their juice as the premium choice. The label became the argument.

Today California's citrus acreage is a fraction of what it was at peak in the 1940s. Urbanization claimed most of the original groves. But what remains is concentrated, premium, and fiercely protected. The industry pivoted from volume to value. The "100% California" label became the marker of that shift.
