Malted rice, a versatile and essential ingredient in both cooking and beverages, results from germinated rice grains. Its unique qualities, achieved through meticulous malting, bring distinct flavors and culinary possibilities beyond traditional rice. I'll be covering malted rice production, its gluten-free characteristics, and the wide range of culinary applications it offers.

🌾 Grain Highlights
- Discover how malted rice, also known as 'kome-koji,' is made from ordinary rice grains into a flavorful ingredient with a distinct, nutty taste.
- I'll guide you step by step through the detailed process of making malted rice. It starts with selecting and cleaning the grains, followed by soaking, germination, and drying, a process that activates enzymes to convert starches into sugars. This transformation is what makes malted rice ideal for both brewing and cooking.
- We'll also explore how malted rice is used in making rice syrup, rice beer, and traditional Japanese dishes like Shio Koji, Amazake, and different kinds of miso. This will highlight its important role in creating both tasty and healthy meals.
🍚 What is Malted Rice?
Malted rice, also referred to as 'kome-koji' in Japan and known as 'nuruk' in Korea, is a product created by germinating rice grains to release enzymes that convert the starches in the rice into sugars. This process, known as malting, involves soaking the rice in water and then allowing it to sprout.
The germinated rice is then dried, halting the sprouting process. It is often used in brewing and distilling to produce alcoholic beverages, as the sugars it contains are fermentable. It's also used in the production of certain types of vinegar and in some culinary applications for its unique flavor profile. The malting process imparts a distinct taste, often described as a slightly nutty and sweeter taste.
⚙️ How is Malted Rice Made?
The creation of this rice involves a series of steps that convert the starch in rice grains into sugars suitable for fermentation. This procedure, referred to as malting, encompasses the following stages:
- Selection and Cleaning: The first step is selecting high-quality white or brown rice grains. These grains are then thoroughly cleaned to remove any impurities or debris. I prefer brown rice for a nuttier flavor and darker hue compared to white rice.
- Soaking: The cleaned rice grains are soaked in water. This soaking rehydrates the grains, preparing them for germination. The duration of soaking can vary, but it typically lasts for several hours or overnight.
- Germination: After soaking, the rice is drained and allowed to germinate. During germination, enzymes are activated within the rice grains. These enzymes start converting the starches in the rice into simpler sugars. Germination is a critical phase and is carefully monitored for temperature and humidity to ensure optimal conditions. This stage usually lasts for a few days.
- Drying: Once the germination process has produced the desired level of enzyme activity and sugar content, the germinated rice (now called malted rice) is dried. Drying halts the germination process. The drying temperature is controlled to preserve the enzymes that are crucial for the malting process.
- Milling (Optional): Depending on its intended use, malted rice may be processed into a finer form, such as malted rice flour. This step is discretionary and contingent on the intended use of the rice.
❓ Is Malted Rice Gluten Free?
Malted rice is generally considered gluten-free. Gluten is a protein found in certain grains like wheat, barley, and rye but not in rice. Since malted rice is made from rice grains that have been germinated and dried, it does not contain gluten inherently.
It's crucial to be aware of cross-contamination risks, especially if malted rice is processed in facilities that handle gluten-containing grains. For those with celiac disease or gluten sensitivity, even trace amounts of gluten can be problematic. To avoid this, seeking out certified gluten-free malt rice products is recommended.
👩🏻🍳 Uses
Malted rice is a key ingredient in various products and culinary preparations, each using its unique properties:
- Rice Syrup: In making this syrup, the enzymes from malted rice break down its starches into sugars. The resulting liquid is then reduced to a syrupy consistency. This natural sweetener is often used as a substitute for maple syrup in cooking and baked goods.
- Rice Beer: Malted rice serves as an adjunct to barley malt for certain beer varieties. It provides additional fermentable sugars, contributing to the alcohol content without significantly altering the beer's color or flavor profile.
- Shio Koji: This is a seasoning made by fermenting rice with salt and koji mold. The malted rice in Shio Koji imparts a unique umami flavor and tenderizes proteins, making it a popular marinade or seasoning in Japanese cuisine.
- Amazake: A traditional Japanese drink, Amazake is made by fermenting rice with koji. It's often consumed as a non-alcoholic, healthful drink that is rich in nutrients.
- Miso Paste: Traditional miso is often made with soybeans, but some varieties, known as 'Kome Miso' or rice miso, incorporate malted rice. This type of miso offers a distinct taste profile, differing from the more common soybean-only (Hatcho Miso) and barley (Mugi Miso) varieties.
🙋♀️ People Also Ask [FAQs]
Is There A Difference Between Malted Rice And Rice Malt?
While often used interchangeably, malted rice generally refers to rice that has undergone malting. Rice malt, on the other hand, often refers to a sweetener made from malted rice or to malted rice itself in brewing contexts. If you're interested, I have also covered some excellent substitutes for rice malt syrup.
How To Store Malted Rice?
It is recommended to store malted rice in a cool, dry location, shielded from direct sunlight and moisture. It's best kept in an airtight container to protect it from humidity and pests.
