Mugicha
Roasted barley, infused hot or cold, and the default household drink of a Japanese summer. Korea’s boricha and China’s damai cha are the same idea arrived at separately.
Identity
- Botanical name
- Hordeum vulgare
- Family
- Poaceae
- Part used
- Seed
- Origin
- Western and central Asia, where barley was domesticated; the drink is East Asian
- Drunk in
- Japan, Korea, China, Taiwan
Character
Toasty and mildly sweet with a clean finish and no astringency. Cold brewing gives a rounder result and is the standard domestic method.
Notes: roasted grain, toast, faint caramel
History
Documented in Japan from the Heian period, when it was a drink of the nobility, and spread to ordinary households in the Edo period. Its modern form as a refrigerated summer staple depends on domestic refrigeration and is a twentieth-century habit.
How it is drunk
Kept in a jug in the refrigerator through the Japanese summer and served to everyone including small children, precisely because it contains no caffeine. Korean households do the same with boricha, often serving it in place of water at meals.
Production
Barley grains are roasted until dark brown, either whole or cracked. Roast depth decides everything: light roasting gives a thin grain drink, dark roasting gives the toasty character the drink is known for.
Preparation
Roasted grain infusion · Cold infusion
Boiling and decoction
1–3 g/100 ml · 98–100 °C · 10 min
Common mistakes
- Steeping it briefly like tea. Barley wants several minutes hot, or hours cold.

Comparisons
- Job’s tears vs barley tea — Job’s tears is called adlay, pearl barley and hatomugi, and is not a barley. The Korean powdered drink made from it is thick and cloudy where barley tea is clear and light.
- Polygonatum vs barley tea — Two roasted, nutty, sweet drinks served in place of water across Korea and Japan. One is a rhizome and the other a grain, and in the cup they are closer than that suggests.
- Corn tea vs barley tea — The two roasted grain drinks of East Asian tables, and they are more often blended together than drunk apart. Corn is the sweeter and barley the more widespread.
- Roasted soybean vs barley tea — Two deeply roasted seed drinks with a malty sweetness, both drunk at the table rather than as a speciality. The legume is heavier in the mouth than the grain by a clear margin.
- Barley tea vs roasted rice — The two roasted grains of Japanese daily drinking, one drunk alone by the jug and the other almost always blended with green tea.

The botanical name, family and distribution above are checked against an external authority. Hordeum vulgare L. — GRIN-Global Taxonomy record— retrieved and read, not countersigned by a named human. That source covers naming and distribution only. Everything else on this page — history, culture, production, flavour, preparation and buying advice — is TeaHQ’s own synthesis with no external source behind it.
Brewing parameters here are typical practice for the category rather than measurements of this plant, and each set says so.
This page makes no safety claim. It describes what Mugicha is, where it comes from and how it is prepared — not what it does to a person. The absence of a safety note here is not a statement that the plant is safe. How TeaHQ handles this.
