Inside Korean refrigerators, a glass pitcher of tea sits where a water jug might elsewhere — grain-roasted, caffeine-free, and brewed fresh every few days. Here are the five teas Korean families keep on hand year-round.
Steeping vs. Boiling — How Korea Drinks Tea Differently
Korea has a formal tea tradition. Carefully cultivated leaves, porcelain cups, water heated to a precise temperature — the practice is called 다도 (dado, the art of tea ceremony), and it still has devoted practitioners.
But that's not what most Korean parents are doing at the stove every week.
The pitcher in the average Korean refrigerator doesn't contain loose-leaf green tea. It contains roasted barley. Or dried corn silk. Or the ground rhizome of a plant most Westerners have never heard of. These are 생활 차 (saenghwal cha) — "everyday teas," brewed in bulk and consumed the way other households go through filtered water.
This is the most distinctive feature of Korean tea culture: the ceremonial and the utterly ordinary coexist without contradiction. Japan has its own version of this duality — matcha for ritual, hojicha for the lunch table — but Korea takes the casual end of that spectrum further than almost any other tea-drinking country.
Think of it the way an Italian household treats espresso: nobody measures the ceremony, nobody writes a poem about it. You pull the cup, you drink it, you go on with your day. Korean saenghwal cha works the same way, except it lives in the refrigerator, ice-cold, and it has no caffeine.
Understanding this distinction changes how you read a Korean meal. When a host sets a pitcher on the table without explanation, they're not offering you tea in the Western sense. They're offering you water — just a more interesting version of it.
No. 1 — Barley Tea, the Default Setting
보리차 (boricha, barley tea) is the pitcher in more Korean refrigerators than any other drink. The preparation is almost aggressively simple: roasted barley goes into boiling water for about ten minutes, the liquid cools, the solids get discarded or left to settle.
The result tastes like toasted grain — faintly smoky, slightly nutty, with a roasted-grain depth that sits somewhere between a very mild coffee and unsweetened cereal milk. It has zero caffeine.
That last point matters more than it might seem. Boricha is the drink Korean families give to everyone — including infants transitioning to solid food, elderly relatives with heart conditions, and anyone who can't tolerate caffeine. A diluted version is often one of the first liquids a Korean baby drinks outside of milk.
In summer, boricha lives in the fridge and gets poured over ice. In winter, it's reheated on the stove or in a kettle and served warm from a thermos flask at the dinner table.
Japan has an almost identical drink — 麦茶 (mugicha) — and the two traditions likely developed independently. Both countries roast barley the same way, brew it the same way, and use it the same way. Cultural historians debate the parallels, but the practical result is the same: a near-waterlike drink that an entire population accepts without question as their default daily liquid.
How to brew it at home: Drop one or two boricha teabags (available at any Korean grocery store, and increasingly at Asian markets worldwide) into one liter of water. Boil for ten minutes. Let it cool to room temperature, then refrigerate. The pitcher keeps for about three days.
No. 2 — Corn Tea, the One That Surprises Every Foreigner
옥수수차 (oksusucha, corn tea) is the drink that startles most non-Korean visitors the first time they encounter it. The taste is sweet and faintly savory — multiple people describe it, unprompted, as "popcorn water," which is an accurate if inelegant description.
There are two distinct varieties. One uses roasted corn kernels; the other uses 옥수수 수염 (oksusu suyeom, corn silk — the thread-like strands hidden inside the husk). The kernel version is nuttier and richer. The silk version is lighter, almost floral, with a gentler sweetness.
Corn silk tea is particularly popular among women in Korea because it's widely believed — and supported by some preliminary research — to act as a mild diuretic and reduce water retention. Whether or not those effects are clinically established at scale, the reputation is strong enough that bottled corn silk tea lines convenience store shelves alongside sports drinks and canned coffee.
Like boricha, oksusucha is caffeine-free. Unlike boricha, it has enough residual sweetness that some people — especially children — prefer it to the more savory barley version.
If you're encountering Korean cuisine for the first time and find a yellowish, slightly sweet drink appearing at the table, this is probably what you're holding.
How to brew it at home: Add a generous handful of dried corn silk or roasted corn kernels to one liter of cold water. Bring to a boil and simmer for fifteen minutes. Strain out the solids, let the liquid cool, and refrigerate. Premade teabags are also widely available and cut the brewing time in half.
No. 3 — Korean Green Tea, Not the One You're Thinking Of
녹차 (nokcha, green tea) is Korea's oldest documented tea tradition. Written records of tea cultivation on the Korean peninsula date to the Silla dynasty (57 BCE–935 CE), and by the Goryeo period (918–1392) — roughly concurrent with medieval Europe — Buddhist monks had turned green tea into a near-sacramental practice.
The two primary growing regions today are 보성 (Boseong, a coastal county in South Jeolla Province) and 하동 (Hadong, on the Gyeongnam border with North Jeolla). Both sit at the southern edge of the peninsula, where the climate is mild enough to sustain delicate tea cultivation, and both have been producing tea for over a thousand years.
Korean nokcha tastes different from Japanese green tea, and the difference is immediately apparent to anyone who drinks both. Japanese sencha and gyokuro tend toward grassy, oceanic, sometimes sharp flavors. Korean nokcha is softer — less astringent, more understated, with a clean, slightly vegetal finish.
The reason is partly the processing method. Traditional Korean green tea is 덖음차 (deokkeum-cha) — pan-fired in a hot iron pot rather than steamed. Pan-firing arrests oxidation while adding a very faint toasty quality that steaming doesn't produce. It's the same principle behind the difference between French and Chinese green teas: the heat application method shapes the final flavor more than almost any other variable.
For serious brewing, Korean tea masters recommend water at 60–70°C (140–158°F) — well below boiling — and an infusion time of about a minute for the first steep. The same leaves can be resteeped two or three times, with each infusion yielding a slightly different flavor profile.
In practice, most Korean households use teabags and boiling water. The ceremonial version is for weekend afternoons or guest occasions, not Tuesday breakfast.
Timing note: Nokcha contains moderate caffeine. Drinking it after a rich or oily meal helps with digestion — that's its most common everyday role. Avoid it within two to three hours of sleep.
No. 4 — Solomon's Seal Tea, Korea's Least-Known Export
둥굴레차 (doonggulleecha, Solomon's seal tea) is the drink on this list that most often produces a blank look from foreigners, even those with a serious interest in Korea. It doesn't appear in K-drama product placements. It isn't sold in the international sections of most Western supermarkets. It's simply something Korean households have been drinking for generations, quietly, without needing external validation.
The plant — 둥굴레 (doonggulleeh, Solomon's seal, Polygonatum odoratum) — grows wild across East Asia and has been used in both Korean folk medicine and Chinese herbal traditions for centuries. The part that goes into tea is the rhizome: the underground stem, dried and roasted.
The flavor sits somewhere between boricha and a mild herbal infusion. Sweeter than barley tea, less nutty, with a faint woodsy note that might remind you of a very gentle ginger tea without the heat. The roasting adds depth without bitterness.
Traditional Korean medicine associates doonggulleecha with fatigue relief and digestive support — claims that fall more into the category of long-held folk belief than rigorously controlled clinical study, but also claims that haven't discouraged generations of Koreans from drinking it daily.
The tea skews older in its fanbase. It's the drink a grandmother might press on you after a meal, kept in a large thermos on the kitchen counter. There is still a generation of Korean women who harvest Solomon's seal from hillside walks in autumn, dry the rhizomes themselves, and consider the store-bought version a poor substitute.
That home-harvest tradition is gradually shrinking. But the tea itself isn't going anywhere.
No. 5 — Citron Tea, the One That Doesn't Behave Like Tea
유자차 (yuja-cha, citron tea) is genuinely different in category from everything else on this list. It isn't brewed from a grain or a plant steeped in hot water. It's made from 유자청 (yuja-cheong, citron preserve) — a thick, marmalade-like preparation of 유자 (yuja, yuzu citron — a rough-skinned East Asian citrus fruit, more aromatic than a lemon, sharper than a mandarin) rind and pulp, macerated in honey or sugar until it breaks down into a fragrant, semi-liquid syrup.
To make yuja-cha, you spoon one or two tablespoons of yuja-cheong into a mug and add hot water. The syrup dissolves, the rind floats, and you're left with something that looks loosely like a hot lemonade and tastes more complex — citrus-forward, floral, with a honeyed sweetness and a slight bitter finish from the rind.
The closest Western equivalent is stirring lemon curd into hot water, though yuja-cheong has a more pronounced perfume than any lemon-based product. Some people who find lemon tea one-dimensional find yuja-cha revelatory.
Its cultural moment in the Korean year is cold weather. Yuja-cha is what you drink when you feel the start of a cold coming on, when the heating isn't quite keeping up, when you want something warm and restorative that isn't entirely sweet. It occupies the same emotional space that chicken broth holds in American households — comfort, specifically.
Jars of yuja-cheong are sold in Korean supermarkets year-round, and the category has expanded: there are now versions made with ginger, with green plum, and with quince. The original yuja version remains the benchmark.
One preparation note: Don't use boiling water if you're using high-quality yuja-cheong with real rind. Water just off the boil — around 90°C (194°F) — preserves the fragrance better than a rolling boil would.

Why the Pitcher Lives in the Refrigerator
The habit of keeping a large pitcher of cold tea in the refrigerator — rather than water — is old enough that most Korean households no longer think about why they do it. But the origin is practical and specific.
For much of the twentieth century, tap water in Korean cities wasn't reliably safe to drink without boiling. Families boiled water anyway; adding a handful of roasted barley or dried corn silk to the pot cost almost nothing and produced something more interesting than plain boiled water. The practice became habit. Habit became culture.
Water filtration became standard in Korean homes from the 1990s onward, and today most Korean apartments have a countertop 정수기 (jeongsugi, water purifier) delivering cold and hot filtered water on demand. The practical necessity is gone.
The pitcher remained anyway. Boricha and oksusucha teabags are still among the fastest-moving items in the drink aisle at every Korean supermarket chain. The habit is now cultural memory rather than practical necessity — the same reason Italian families still make Sunday sauce even when there's a perfectly good restaurant downstairs.
If you're ever a guest in a Korean home and the host opens the refrigerator and pours you a glass of something brown or yellowish without explanation, they haven't forgotten to ask your preference. That is your drink. That's the default.
What it tastes like is something you should form your own opinion on. Most people, once they've had a cold glass of boricha on a warm afternoon, find they didn't need explaining at all.
Frequently Asked Questions
Is barley tea actually healthy, or is it just marketing?
Barley tea's health reputation is modest but reasonably grounded. It contains no caffeine, making it genuinely safe for people avoiding stimulants. Roasted barley contains antioxidants, and some small studies suggest it may have mild anti-inflammatory properties. More concretely, it's simply a way to stay hydrated without sugar, artificial sweeteners, or caffeine — which puts it ahead of most commercial beverages by default. Korean doctors routinely recommend it for children and the elderly. The health claims you'll see on commercial packaging lean further than the evidence strictly supports, but as a daily hydration habit, boricha is about as benign as drinks get.
How much does Korean tea cost, and where can I buy it outside Korea?
Teabag versions of boricha, oksusucha, and nokcha are inexpensive globally. A box of 30–50 boricha teabags at a Korean grocery store (H Mart in the U.S., T&T in Canada, most Asian supermarkets in the UK and Australia) runs roughly $3–6 USD (3,500–7,000 KRW in Korea). Yuja-cheong jars range from $8–15 USD depending on quality. Doonggulleecha is the hardest to find outside Korea but is available on Amazon and through Korean online retailers shipping internationally. In Korea itself, all five are available at every major supermarket chain — Emart, Homeplus, Lotte Mart — at lower prices than abroad.
What's the best time of year to drink each of these Korean teas?
Boricha and oksusucha are genuinely year-round drinks, though they peak in summer when the refrigerator pitcher gets refilled most often. Nokcha is most appreciated in spring, when new-harvest leaves arrive from Boseong and Hadong — Korean tea drinkers anticipate the first spring flush the way wine drinkers track vintage releases. Doonggulleecha tends to be a cooler-weather comfort drink, though it has no hard season. Yuja-cha is almost exclusively an autumn and winter drink in Korean households — its association with cold relief means it feels incongruous in July, however good it tastes. Time of day matters too: nokcha before 4 p.m., yuja-cha after dinner or before bed.
Can foreigners find Korean teas at cafés in Korea, or only at home?
Nokcha is widely available at Korean cafés — major chains like Caféin and Hollys Coffee carry green tea lattes, and specialty tea houses in neighborhoods like Insadong and Bukchon offer traditional loose-leaf versions. Yuja-cha appears on café menus seasonally, especially October through February. Boricha and doonggulleecha are harder to find commercially because they're so cheap to make at home that no one thinks to charge for them. Some traditional Korean restaurants serve boricha as a table drink in place of water — it arrives in a metal pot without being ordered. Oksusucha in can or bottle form is available at every convenience store (GS25, CU, 7-Eleven Korea) for around 1,500–2,000 KRW.
What's the difference between Korean green tea and Japanese green tea?
The most important difference is processing. Japanese green tea is typically steamed immediately after harvest, which locks in chlorophyll and creates the grassy, oceanic flavor associated with sencha or gyokuro. Korean green tea is pan-fired in a hot iron wok — a technique called deokkeum — which produces a slightly toastier, softer flavor with less astringency. Korean nokcha also tends to be lighter-bodied than most Japanese green teas. Neither is superior; they're genuinely different products. If you find Japanese green tea too sharp or vegetal, Korean nokcha is worth trying. If you want the umami depth of high-grade gyokuro, Korean green tea won't replicate it.
Why do Koreans use tea instead of water as their everyday drink?
The short answer is historical habit that became cultural identity. Before widespread water purification — largely the 1980s and 1990s in Korea — boiling water was a daily necessity, and adding roasted grain to the pot cost almost nothing. The resulting drinks were pleasant, hydrating, and caffeine-free, which made them suitable for all ages. By the time tap water and home filtration systems became reliable, the habit was embedded in domestic routine. There's also a flavor preference component: Koreans who grow up drinking boricha often find plain water comparatively flat. The pitcher of cold grain tea is simply what thirst looks like in a Korean kitchen.
Is corn silk tea safe to drink every day, and does it really reduce bloating?
Corn silk tea is considered safe for daily consumption by most health authorities — it has no known toxicity at normal drinking quantities and has been consumed daily in Korea and parts of China for generations without documented harm. The diuretic effect is real but mild; corn silk contains compounds called maysin and stigmasterol that have shown diuretic activity in animal studies, and the drink does appear to modestly increase urine output in humans. Whether this translates to meaningful bloating or water retention relief varies by individual. People with kidney conditions should consult a doctor before drinking it daily in large amounts, as with any mild diuretic. For healthy adults, a one-liter pitcher per day is within normal Korean household consumption patterns.
