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.

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.

Comparisons

  • Job’s tears vs barley teaJob’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 teaTwo 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 teaThe 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 teaTwo 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 riceThe two roasted grains of Japanese daily drinking, one drunk alone by the jug and the other almost always blended with green tea.
