How do you make sprouted brown rice at home? Rinse whole brown rice, soak it in clean water, then drain and keep it moist and covered, rinsing a few times a day until a tiny white tip appears. Stop before the sprout is longer than the grain, then cook it fully. White rice will not sprout because milling removes the germ.
Key takeaway: Sprouted brown rice, also called germinated brown rice or GABA rice, is whole brown rice soaked until it starts to germinate. A Thai study found soaking at 91°F (33°C) for 300 minutes raised GABA from 6.71 to 18.74 mg/100 g. The Whole Grains Council counts it as whole grain if the sprout is no longer than the kernel. Cook it fully and chill leftovers fast.

What Is Sprouted Brown Rice?
Sprouted brown rice is whole brown rice that has been soaked and kept moist until the germ starts to grow. It is sold in the US as germinated brown rice, GABA rice or by the Japanese name hatsuga genmai. The Whole Grains Council says sprouted grains still count as whole grains as long as the sprout is no longer than the kernel.
Only brown rice works. Milling white rice removes the bran and the germ, so there is nothing left to sprout. Parboiled and instant brown rice have been heat-treated and usually will not germinate either. Buy plain, raw brown rice and check the date, because old rice sprouts poorly.
- Short or medium grain: soft texture after sprouting.
- Long grain: firmer, separate grains.
- Not suitable: white, parboiled or instant rice.
How Do You Sprout Brown Rice at Home?
Sprouted brown rice needs only a bowl, a jar or strainer and clean water. The steps match other grain sprouts in our sprouting seeds guide: soak, drain, keep moist and rinse until the tip shows. Warmth speeds it up, but warm, wet grain also grows bacteria, so rinse often and keep everything clean.
- Rinse 1 to 2 cups of brown rice until the water runs clear.
- Cover with 2 to 3 times as much clean, cool water and soak for several hours.
- Drain, then keep the rice in a covered strainer or jar at room temperature.
- Rinse and drain 2 to 3 times a day.
- Stop when most grains show a tiny white tip, before it passes kernel length.
- Cook right away, or refrigerate and cook within a day.
A sprouting jar with a mesh lid makes draining easy.
How Long Does Brown Rice Take to Sprout?
At home it usually takes about 1 to 2 days in a warm room, depending on the rice and the temperature. Watch the grain, not the clock: stop at the first visible tip. In the 2018 Thai study on Phitsanulok 2 rice, both a warmer soak and a longer soak raised GABA, with the best result at 91°F (33°C) for 300 minutes.
- Soak: several hours; that study found 5 hours at 91°F (33°C) best for GABA.
- Germination: about 1–2 days at room temperature.
- Stop point: a tip about 0.04 in (1 mm) long, shorter than the grain.
- Too far: long sprouts, sour smell or slime.
Does Sprouted Brown Rice Have More GABA and Nutrients?
Studies say yes for GABA. In the 2018 study, GABA rose from 6.71 mg/100 g in raw rice to 18.74 mg/100 g, and total phenolics also rose. The Whole Grains Council reports an Ecuador study in which fiber rose 6.1 to 13.6% with sprouting and phytic acid dropped noticeably across six varieties.
Health claims are another matter. These studies measured what is in sprouted brown rice, not whether eating it treats any condition. Enjoy it for its softer texture and sweeter flavor, and see claims about blood pressure or sleep as unproven unless a medical source backs them.
Is Sprouted Brown Rice Safe to Make at Home?
It is safe with clean handling and full cooking. Food Standards Australia New Zealand (FSANZ) lists cooked rice among the foods at higher risk for Bacillus cereus. Its advice is to cook food thoroughly, serve it right away or keep it hot, and cool leftovers quickly in a fridge at 41°F (5°C) or colder.
- Clean gear: wash bowls and strainers in hot, soapy water first.
- Fresh water: change the soak water and rinse often.
- Toss bad batches: sour smell or slime means start over.
- Leftovers: FSANZ says eat within 3–4 days, or within 1 day for vulnerable people.
How Do You Cook Sprouted Brown Rice?
Cook sprouted brown rice like regular brown rice but with a little less water and time, since the grains have already absorbed water. A rice cooker’s brown-rice or GABA setting works well. Start with about 1 1/4 to 1 1/2 cups of water per cup of sprouted rice and adjust next time for texture.
- Drain the sprouted rice well.
- Add water at about 1 1/4–1 1/2 cups per cup of rice (300–360 mL per 240 mL).
- Simmer covered until tender, often 25 to 35 minutes on the stove.
- Rest 10 minutes, then fluff.
- Cool leftovers quickly and refrigerate.
For other easy grain sprouts, try sprouted wheat berries or quinoa sprouts.
FAQ About Sprouted Brown Rice
Can you sprout white rice?
No; milling removes the germ, so only brown rice sprouts.
How long should brown rice soak for GABA?
A 2018 study found 5 hours at 91°F (33°C) gave the most GABA.
When is sprouted rice ready?
When a tiny tip shows, before the sprout is as long as the grain.
Is sprouted brown rice still whole grain?
Yes, if the sprout is no longer than the kernel.
How do you store cooked sprouted rice?
Cool it fast and refrigerate at 41°F (5°C) or colder.
Does sprouted rice cook faster?
Usually a little faster, with less water.
