Roasted barley tea has been enjoyed across East Asia for centuries as a refreshing, naturally caffeine-free drink. Known as mugicha in Japan and boricha in Korea, this comforting tea is made by steeping roasted barley kernels in hot or cold water, producing a mild, nutty flavour that can be enjoyed throughout the year.
Today, roasted barley tea is becoming increasingly popular among health-conscious consumers looking for alternatives to coffee, sugary drinks and traditional teas. While research into some traditional uses is still ongoing, roasted barley tea contains naturally occurring antioxidants and other plant compounds that may support overall wellness as part of a balanced lifestyle.
Whether you're already a fan of barley or simply looking to add more wholesome drinks to your daily routine, this guide explores the potential health benefits of roasted barley tea, what the science says and how to enjoy it at home.
What Is Roasted Barley Tea?
Roasted barley tea is made by roasting whole barley grains before steeping them in water. Unlike green or black tea, it contains no caffeine, making it suitable for enjoying throughout the day or in the evening.
The roasting process creates its distinctive toasted aroma and rich, slightly nutty taste. Depending on personal preference, roasted barley tea can be served hot during colder months or chilled over ice as a refreshing summer drink.

Nutritional Profile of Roasted Barley Tea
Although roasted barley tea is low in calories, it contains naturally occurring plant compounds produced during the roasting process.
These include:
- Antioxidants
- Polyphenols
- Pyrazines, which are responsible for its roasted aroma
- Trace minerals extracted during brewing
Because it contains no sugar, caffeine or artificial ingredients when prepared traditionally, roasted barley tea is a refreshing beverage choice for many people. For a full nutrient breakdown of barley itself, see the USDA FoodData Central database.
Potential Health Benefits of Roasted Barley Tea
1. Rich in Antioxidants
One of the most widely studied benefits of roasted barley tea is its antioxidant activity.
Research published in Bioscience, Biotechnology, and Biochemistry identified several antioxidant compounds formed during the roasting process. These compounds may help neutralise free radicals, which are unstable molecules that contribute to oxidative stress within the body. A related study indexed on the U.S. National Library of Medicine's PubMed database examined the antioxidant properties of aqueous extracts of roasted hulled barley.
Although roasted barley tea should not be viewed as a treatment for disease, consuming antioxidant-rich foods and beverages is widely recognised as part of a healthy, balanced diet.

2. Naturally Caffeine-Free
Unlike coffee or traditional tea, roasted barley tea contains no caffeine. According to the U.S. Food and Drug Administration (FDA), caffeine can be part of a healthy diet for most people, but too much may pose health risks — making naturally caffeine-free drinks like barley tea a gentler everyday option.
This makes it an excellent option for people who:
- Want to reduce caffeine intake
- Are sensitive to caffeine
- Prefer a relaxing evening beverage
- Want a family-friendly drink
Many people also enjoy replacing sugary soft drinks with chilled barley tea during warmer months.
3. May Support Oral Health
Some laboratory studies suggest roasted barley tea may help reduce the adhesion of certain oral bacteria responsible for plaque formation.
Research published in the Journal of Agricultural and Food Chemistry found that roasted barley tea inhibited bacterial attachment under laboratory conditions. While more human studies are needed, these findings highlight another interesting area of ongoing research.
Good oral hygiene should always include regular brushing, flossing and dental check-ups.
4. May Help Support Healthy Circulation
Early research has investigated compounds formed during roasting, particularly alkylpyrazines, which contribute to roasted barley tea's characteristic aroma.
Some studies suggest these compounds may influence blood fluidity under specific laboratory conditions. Although these findings are promising, further clinical research is needed before firm health conclusions can be drawn.
As with any food or beverage, roasted barley tea should be enjoyed as part of an overall healthy lifestyle rather than being relied upon for specific health outcomes.
5. A Hydrating Everyday Beverage
Since roasted barley tea contains no caffeine, it can contribute to your daily fluid intake without the stimulating effects associated with caffeinated drinks.
Served hot or cold, it provides a refreshing alternative to:
- Coffee
- Black tea
- Sweetened beverages
- Soft drinks
Many households in Japan and Korea enjoy chilled roasted barley tea throughout the summer as an everyday drink.
