Boricha is Korean roasted barley tea, and making it takes about 10 minutes on the stovetop. You bring water to a boil, add roasted barley, and simmer briefly. The result is a nutty, slightly toasty drink that Koreans serve hot in winter and chilled in summer as an everyday alternative to water. It’s completely caffeine-free.
What You Need
The ingredient list is short: roasted barley and water. The standard ratio is about 3 tablespoons of roasted barley grains per 2 liters of water. You can adjust up or down depending on how strong you like it.
The easiest route is buying pre-roasted barley, which is sold at Korean and Asian grocery stores (look for 보리차 on the package). It comes either as loose roasted grains or in pre-portioned tea bags. Loose grains give you more control over strength. Tea bags are more convenient but brew slightly differently, since the barley is usually milled finer inside.
Stovetop Hot Brew Method
This is the classic approach and the one most Korean households use:
- Bring 2 liters of water to a rapid boil in a pot or kettle.
- Add 3 tablespoons of roasted barley grains. If you have a tea strainer basket, use it for easy cleanup.
- Reduce heat to low or medium-low and let it simmer for 5 to 20 minutes. Five minutes gives a light, mild tea. Ten to twenty minutes produces a deeper, more roasted flavor.
- Remove the barley grains or strainer once the tea reaches your preferred strength.
The tea should turn a warm amber or light brown. If you let the grains sit too long after cooking, the flavor can turn slightly bitter, so pull them out once it tastes right to you. To serve it cold, just let it cool to room temperature and transfer to a pitcher in the fridge.
Cold Brew Method
If you prefer a smoother, milder version or just want to prep a pitcher overnight, cold brewing works well. Place roasted barley grains or a tea bag into a pitcher of room temperature water, then refrigerate. It needs at least a few hours, but leaving it overnight produces the best flavor. Remove the grains or tea bag before drinking.
Cold-brewed boricha tastes lighter and less bitter than the hot-brewed version. It’s a good option for summer, and many Korean families keep a pitcher running in the fridge at all times, refilling it as a household staple.
Roasting Your Own Barley
If you can’t find pre-roasted barley, you can toast raw barley at home on the stovetop. Use a dry skillet (no oil) over medium heat and spread the barley in a single layer. Stir frequently to prevent burning. You’re looking for the grains to turn a deep golden brown and smell nutty and toasty, which takes roughly 10 to 15 minutes depending on your heat level.
The color of the finished grain matters more than you might think. Research on roasted barley found that darker-roasted grains actually contain less acrylamide (a compound that forms when starchy foods are heated) than medium-roasted ones. Acrylamide levels peak when barley is roasted at moderate temperatures and then decrease with deeper roasting. So aiming for a rich, dark golden color rather than a pale toast is both better for flavor and a reasonable approach from a safety standpoint. Just don’t let them blacken, which tastes burnt and ashy.
Flavor and How It Compares to Other Teas
Boricha has a clean, roasted grain flavor that’s slightly smoky with a faint bitter finish. It’s not sweet at all, which is part of its appeal as a mealtime and all-day drink. Think of it as closer to the flavor of toasted bread or roasted nuts than to any herbal tea.
A popular variation in Korean households is mixing roasted barley with roasted corn tea (oksusu-cha). The corn adds a natural sweetness that balances the barley’s slight bitterness. You can buy roasted corn kernels at the same stores that sell roasted barley and simply toss both into the pot together. Some people also add dried corn silk, which has a very delicate flavor on its own but rounds out the blend nicely.
Nutrition and Health Profile
Boricha is calorie-free and contains zero caffeine, making it a practical substitute for water throughout the day. The nutritional transfer from grain to tea is modest. Potassium is the most abundant mineral in brewed barley tea at about 13.2 mg per 100 grams, while calcium, sodium, and iron are present only in trace amounts below 2 mg.
Researchers have identified twelve phenolic acids in barley tea, including compounds in the ferulic and coumaric acid families, which function as antioxidants. The roasting process also creates unique metabolites not found in raw barley, contributing to both the flavor and the antioxidant profile. Whole barley grain is rich in B vitamins, iron, zinc, and manganese, though how much of that actually makes it into the brewed tea is still unclear.
In Korean tradition, boricha is considered gentle on the stomach and good for digestion. It’s commonly served alongside meals, and its mild flavor doesn’t compete with food the way coffee or flavored drinks do.
Storage Tips
Brewed boricha keeps well in the refrigerator for 2 to 3 days. After that, the flavor dulls and it can develop an off taste. Store unbrewed roasted barley grains in an airtight container in a cool, dry place, where they’ll stay fresh for several months. If you roasted your own, let them cool completely before storing to avoid trapping moisture.
