Calrose rice

History

Calrose (USDA # C.I. 8988) originated from and was developed at the Rice Experiment Station near Biggs, California, and released to California growers in 1948. It grew in popularity with growers, marketers, and consumers to become the prominent rice variety in California until the late 1970s. Specific processing and cooking properties were associated with Calrose.

Over the years, improved new varieties of Calrose grain cooking and processing characteristics were released. These medium-sized grains were commingled with Calrose in storage, and later replaced the variety in commercial production, due to their superior performance at many levels. Although that variety of Calrose is no longer grown, Calrose has become a name recognized both in trade and the marketplace for the California-type, medium-grain rice. The name "rose" indicates its medium-grain shape ("Blue Rose" is an earlier medium-grain developed in Louisiana), and "Cal" pays homage to California, the state of the grain’s origin and production. Eighty percent of the California rice crop is Calrose rice.
