Barley Tea
Herbal infusion
About this tea
Barley tea is a roasted-grain infusion — not a true tea — made by steeping or boiling kernels of roasted barley in water. Known as mugicha in Japan, boricha in Korea, and damai cha in China, it is a caffeine-free everyday staple enjoyed steaming hot in winter and ice-cold by the pitcher in summer. The roasting gives it a warm, nutty, toasty character with gentle malt sweetness and a clean, slightly bitter finish. Beloved for being soothing on the stomach and endlessly refreshing, barley tea is one of the most widely consumed household beverages across East Asia.

Origin & Production
Barley tea originates in the grain-growing regions of East Asia, where barley has been a staple cereal for millennia. In Japan it is the quintessential summer drink, brewed by the pitcher in nearly every home. Korea adopted boricha as an everyday substitute for plain water, often served at the table in restaurants. China brews damai cha as a digestive and cooling drink. The barley itself is grown in temperate farmland — much of Japan's mugicha barley comes from regions like Tochigi and Kyushu — and the finished product is sold as whole roasted kernels, ground granules, or convenient brewing bags.
Production process
Harvesting & cleaning
Mature barley kernels are harvested, threshed, and cleaned. Both hulled and unhulled barley are used; the grain is sorted to remove chaff and debris before roasting.
Roasting
The defining step: kernels are dry-roasted at high heat until deep brown and aromatic. Roasting develops the toasty, nutty, malty flavor and the rich amber color, while driving off any raw grain taste.
Cooling & grading
Roasted kernels are cooled quickly to lock in aroma. They are graded by roast level — lighter roasts give a softer, sweeter cup, darker roasts a bolder, more bitter brew.
Packaging
The product is packed as whole roasted kernels for boiling, as coarse granules, or sealed into single-serve brewing bags. Airtight packaging protects the volatile roasted aroma from going stale.
History & Tradition
Barley tea has been part of East Asian daily life for centuries, evolving from a court and warrior-class refreshment into the universal household drink it is today.
Early Japanese roots
Roasted barley infusions are recorded in Japan as early as the Heian period (794–1185), when the drink was enjoyed by the aristocracy as a warming, caffeine-free beverage.
Samurai refreshment
By the warring-states Sengoku era, mugicha was a popular drink among samurai and common people alike, valued for being inexpensive, hydrating, and free of caffeine's stimulation.
Teahouse popularity
During the Edo period (1603–1868), mugicha-jaya (barley tea stalls) appeared in cities, selling cups of the roasted brew to travelers and townsfolk as a cooling summer refreshment.
Home refrigeration
The spread of home refrigerators in the 20th century turned iced barley tea into the defining drink of the Japanese and Korean summer, brewed by the pitcher and kept cold in the fridge.
Bottled & convenient
Ready-to-drink bottled mugicha and boricha and single-serve brewing bags became supermarket staples, cementing barley tea as an everyday substitute for plain water across East Asia.
Health Benefits

Barley tea contains no caffeine, making it a gentle all-day drink suitable for children, evenings, and anyone avoiding stimulants. It is widely used as a flavorful alternative to plain water.
Soothing for digestion
Traditionally sipped after meals, the warm roasted infusion is regarded across East Asia as comforting and easy on the stomach, a familiar part of everyday digestive routines.

Its caffeine-free, mellow profile makes barley tea a fitting drink for unwinding in the evening or sharing at the family table without disturbing sleep.
