Calrose is a medium grain rice variety, notable for being the founding variety of the California rice industry.
History
[edit]
Calrose (USDA # C.I. 8988) originated from and was developed at the Rice Experiment Station near Biggs, California,[1] and released to California growers in 1948.[2] 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.[3]
Availability
[edit]Calrose rice is the most recognized variety of California rice in the United States and abroad, especially in the Pacific.[citation needed] The variety is grown in other areas of the world where growing conditions are suitable, such as Australia.
After cooking, Calrose rice grains are soft and stick together, making it good for use in sushi.[citation needed]
Calrose was once a much sought-after variety in Korea, where it was considered exotic. There was even a black market for the variety, and it was smuggled in large quantities.[4]

Grain Properties
Calrose rice is classified as a medium-grain variety of japonica rice (Oryza sativa), characterized by milled grains measuring approximately 6.1 to 6.6 mm in length.[1] This classification places it within the temperate japonica subspecies, which features shorter, plumper kernels compared to the elongated grains of indica types.[3] As the foundational variety developed in California, it set the standard for subsequent medium-grain cultivars in the region.[1] In its uncooked form, Calrose rice presents as pearly white and semi-translucent grains, offering a clean, uniform appearance typical of well-milled japonica varieties.[4] The grains are short and rounded, contributing to their compact storage and handling efficiency in processing. Upon cooking, Calrose rice develops a soft, tender texture where the grains cling together moderately due to its low amylose content (typically 16.5–17.8%), resulting in a cohesive yet not excessively sticky consistency.[1] This moderate adhesion distinguishes it from long-grain rices, which remain fluffy and separate, and short-grain varieties, which become highly glutinous and moldable.[5] The cooked grains typically expand to about three times their uncooked volume, providing a plump, moist profile suitable for versatile applications.[6] Calrose rice exhibits a mild aroma with subtle nutty undertones and a neutral flavor profile that readily absorbs seasonings and complementary ingredients.[4] This understated sensory character enhances its adaptability in diverse culinary contexts without overpowering other flavors.[4]Nutritional Profile
Calrose rice, when cooked, provides a macronutrient profile typical of medium-grain white rice varieties. Per 100 grams of cooked white Calrose rice, it contains approximately 28 grams of carbohydrates, primarily in the form of starch, 2.4 grams of protein, 0.2 grams of fat, and 0.4 grams of dietary fiber.[7] Key micronutrients in cooked white Calrose rice include manganese at about 0.47 milligrams per 100 grams, supplying roughly 20% of the daily value (DV), selenium at 7.5 micrograms (14% DV), and B vitamins such as niacin (1.4 milligrams, 9% DV) and thiamin (0.17 milligrams, 14% DV); it is low in sodium (1 milligram) and contains no cholesterol.[7] The caloric value of cooked white Calrose rice is approximately 130 kilocalories per 100 grams, positioning it as an energy-dense staple food in many diets.[7] Calrose rice has a high glycemic index of 83, attributed to its medium-grain structure and higher amylopectin content, which influences blood sugar response.[8] Brown Calrose rice, retaining the bran layer, offers higher fiber content (about 1.8 grams per 100 grams cooked) and greater levels of antioxidants compared to the white milled version, enhancing its nutritional density.[9]| Nutrient (per 100g cooked white Calrose rice) | Amount | % Daily Value |
