What is Grain Tea?
Grain tea is a traditional caffeine-free infusion made by roasting grains, seeds, and cereals and steeping them in hot water. Deeply embedded in Korean and East Asian daily life, grain teas are celebrated for their toasty, nutty flavors and gentle health benefits.
Popular Types of Grain Tea
- Barley Tea (Boricha, 돴리차) – The most iconic Korean grain tea. Roasted barley gives a deep, toasty flavor that is refreshing cold in summer and warming hot in winter. A staple in Korean households and restaurants.
- Brown Rice Tea (Hyeonmicha, 현미차) – Made from roasted brown rice, this tea has a mild, nutty flavor and a beautiful golden color. Often blended with green tea (Genmaicha in Japan).
- Corn Silk Tea (Oksusucha, 옥수수차) – Brewed from dried corn silk, this light and slightly sweet tea is traditionally used to support kidney health and reduce bloating.
- Job's Tears Tea (Yulmucha, 율무차) – Made from Job's tears grain, this creamy, nourishing tea is prized for its skin-brightening and digestive benefits.
- Roasted Soybean Tea (Koncha, 콩차) – Rich, earthy, and warming, made from roasted soybeans. A protein-rich, deeply satisfying grain infusion.
Health Benefits of Grain Tea
Grain teas are naturally caffeine-free and offer a range of health benefits. Barley tea is rich in antioxidants and supports digestion. Corn silk tea is known for its diuretic properties. Job's tears tea is celebrated for skin health and anti-inflammatory effects. Brown rice tea provides a gentle energy boost without caffeine.
How to Brew Grain Tea
- Bring water to a full boil (100°C).
- Add grain tea bags or loose grains to the water.
- Simmer for 5–10 minutes for a richer flavor, or steep for 3–5 minutes for a lighter brew.

Grain teas are wonderfully versatile. Serve barley tea as a table water substitute, enjoy brown rice tea alongside meals, or sip corn silk tea throughout the day for gentle hydration support. Most grain teas can be enjoyed without any sweetener.
