Addressing Climate Change and Evolving Market Demands

When people think of rice, they often imagine aromatic basmati or sticky Japanese sushi rice. But in the United States—especially in California—Calrose rice holds a place of its own. As a medium-grain variety with the perfect balance of texture and flavor, Calrose has quietly become a staple in homes and restaurants alike.

What is Calrose?

Calrose is a medium-grain rice variety developed specifically for California’s climate.

  • It’s rounder and shorter than long grain rice.
  • When cooked, it becomes slightly sticky but still holds its shape well.
  • It’s ideal for dishes like sushi, rice bowls, poke, and even 비빔밥(bibimbap).

Its soft, moist texture and ability to absorb flavors have made it a favorite in both Asian cuisine and fusion-style cooking across the U.S.

The U.S. Rice Market: Long Grain vs Medium/Short Grain

The U.S. rice industry is largely divided into two market segments:

  • Long Grain Rice: Grown mostly in Southern states like Arkansas and Louisiana; preferred for its fluffier, less sticky texture.
  • Medium Grain Rice: Dominated by California, used in Asian dishes and gaining popularity across diverse cuisines.

Among medium grain varieties, Calrose is by far the most dominant, accounting for 70–80% of all medium-grain rice production in the U.S.

Market Size of Calrose Rice

Based on 2023 USDA data:

  • Total U.S. medium-grain rice production: approx. 2.87 million metric tons
  • Calrose share (estimated 70–80%): around 2.0–2.3 million metric tons
  • At an average farm price of $0.46 per kg (based on $21/cwt),
    👉 the Calrose market size is roughly $900 million to $1.2 billion USD

That’s a huge number for a single variety—and it reflects Calrose’s continued relevance in both domestic and export markets.

Where is Calrose Grown?

Calrose rice is grown almost exclusively in California, particularly in the fertile plains of:

  • Sacramento Valley
  • Counties like Colusa, Butte, Glenn, and Yolo

These areas offer ideal growing conditions—plentiful water, warm days, and cool nights—that help produce high-quality medium-grain rice year after year.

  1. Perfect Texture
  • Slight stickiness, but not overly glutinous. Great for both traditional and modern dishes.

2. Holds Shape After Cooking

  • Makes it ideal for sushi, rice bowls, and dishes requiring defined grains.

3. Reliable and Productive for Farmers

  • Consistent yields and disease resistance make it an efficient crop for California growers.

4. Widely Available

  • Found in mainstream retailers like Walmart, Costco, and on Amazon.
  • Popular among Asian-American households and increasingly among general consumers.

The History of Calrose

(Source: Kenyon review)

  • Developed in 1948 by the California Cooperative Rice Research Foundation
  • The name “Calrose” comes from:
    • “Cal” = California
    • “rose” = referencing the shape and quality of the grain, likened to the delicacy of a rose

Originally bred to meet the needs of the growing Japanese-American population and the rise of sushi culture in California, Calrose quickly became the standard for U.S. medium-grain rice.

Today, it’s not only a domestic favorite but also a major export to markets like Japan, South Korea, and the Middle East.

Calrose is more than just a rice variety—it’s a cultural bridge between East and West, tradition and innovation. As America’s most recognized medium-grain rice, it plays a vital role in the U.S. agricultural landscape and in kitchens around the world.

So next time you enjoy a sushi roll, a comforting rice bowl, or even a homemade bibimbap, there’s a good chance Calrose was part of the story.
