Every Korean kitchen from the 1980s and 90s had one: a thick, ridged glass bottle, originally filled with Delmonte orange juice, that never quite made it to the recycling bin once the juice was gone. It got rinsed out, refilled with something pale amber, and set in the refrigerator door, where it stayed for years. Ask anyone who grew up with one what was actually inside, and the answer is almost always the same. Boricha — barley tea, brewed dark and cold, the default drink of a Korean summer whether anyone thought to call it that or not.
That bottle is retired now, replaced by whatever pitcher happens to be on hand, but the habit survived it completely. Walk into plenty of Korean restaurants today and a pitcher of boricha will land on the table before you've even opened the menu, the way other countries might set down tap water. It's the closest thing Korea has to a national default beverage — caffeine-free, faintly sweet without any sugar in it, and so unremarkable in the best way that most people never stop to ask how a roasted grain ended up as everyone's house water. The answer starts with the grain itself.
A Grain That Colors Winter Fields Green
Barley is a winter crop, which already sets it apart from most of what grows in a Korean field. It goes into the ground in October or November, right as rice fields are being cleared, and spends the coldest months as one of the only green things visible on the landscape — hollow-stemmed stalks that grow chest-high, tipped with slender spikes of grain that ripen the following April and May. By early summer, just as the rice paddies are being flooded and replanted, the barley is ready to harvest. The timing used to matter more than it does now: the gap between last year's rice running out and that year's barley coming in was tight enough to have its own name, boritgogae, "the barley hill," though these days it survives mostly as an expression rather than a lived experience.
What actually gets harvested comes in two forms. Geotbori, or hull-on barley, holds onto its outer husk even after threshing, which is exactly what makes it the barley of choice for roasting into tea, brewing into malt, or fermenting into gochujang — the husk toasts beautifully and adds body to whatever it's steeped in. Ssalbori, or hull-less barley, threshes clean the way rice does, which makes it the barley people actually cook and eat, mixed into rice or eaten on its own. Korea grows both, with geotbori more associated with the southeast and ssalbori with the southwest, though today plenty of households simply buy whichever their local market carries.
For all the ways Korean cooking uses barley — in rice, in malt, in paste — its most enduring role might be the simplest one: roasted whole in a dry pan until it darkens, then simmered briefly in water. That one step is where boricha begins, and where a fairly plain grain harvested in the last cool days before summer turns into the drink that will define the hottest months ahead.
Boiling the Water, and What Went Into It
Buying water to drink is a fairly recent idea in Korea. Bottled water was actually illegal to sell domestically until 1994, available only to foreign visitors around the 1988 Olympics, so for most of the twentieth century, drinking water simply meant tap water — usually boiled first, especially in older buildings where aging pipes and infrequently cleaned water tanks gave people good reason to be cautious. But a pot of plain boiled water isn't especially pleasant to drink; it tends to taste flat, and depending on the plumbing, it can carry a faint chlorine edge. Roasted barley solved both problems at once, and in summer it did something more: cooled, it turned a chore into the thing everyone actually wanted to drink once the heat set in.
That's also why boricha, alone among Korean teas, is sold in oversized tea bags built for boiling a full pot at once rather than steeping a single cup — a whole kettle, made to outlast a hot afternoon. The practice became so routine that plenty of Korean kids who grew up in the 1980s and 90s genuinely assumed that boiled water simply turned into boricha, and in July and August, the fridge was rarely without a pitcher of it sweating quietly on the shelf.
The habit of boiling tap water at home faded for reasons that had little to do with barley itself. A shift in public confidence around tap water quality in the early 1990s changed things, bottled water was legalized a few years later, and water purifiers gradually became standard kitchen fixtures. But the drink that habit left behind never really needed defending on its own merits. Summer in Korea still runs on it — a pitcher in the fridge, a glass poured over ice without much ceremony, and a table at nearly any restaurant where it shows up before you've even opened the menu.
Roasting Your Own
There's a specific smell that marks a Korean kitchen in early summer: something between popcorn and toasted nuts, drifting from a dry skillet where a handful of barley is turning from pale to deep brown. That's the whole method, more or less. Barley tea is traditionally made with one of the two plain varieties described earlier, geotbori for a deeper, more full-bodied aroma, or ssalbori, which roasts a little lighter and cleaner. Both are traditional, and the choice mostly comes down to what's on hand, which is also why specialty barleys, like this black barley rice grown on Jeju's Aewol coast, roast into a perfectly good cup too, just with their own character. This one in particular comes out closer to cocoa than the usual amber, since the same anthocyanins responsible for its dark color seem to deepen the toastiness as it roasts.
Making it at home is less a recipe than a rhythm. Spread the grains in a dry skillet over low heat and shake the pan often, watching for the color to darken and the smell to shift from raw grain to something closer to popcorn, roasted nuts, and, right at the end, a whisper of cocoa. That transition usually takes ten to fifteen minutes, and it's worth resisting the urge to rush it, since barley roasted too lightly makes a thin, grassy tea instead of a rounded one. Once roasted, simmer about two tablespoons of grains, roughly 15 grams, per liter of water for ten minutes, then strain.
From there, boricha earns its keep both ways. Drink it warm and it's genuinely soothing, the kind of thing that settles a meal the way tea does elsewhere. But let it cool completely and pour it over ice, and it turns into something else entirely: glassy, deeply savory-sweet, almost smoky, with a finish that's more refreshing than a plain glass of water has any right to be. Most Korean households treat the hot version as an afterthought and save the real enthusiasm for the cold pitcher, and it's hard to argue with that instinct once you've tried both.
Made in batches, it keeps in the refrigerator for several days, which is exactly how most families have always treated it, less something to prepare fresh each time than a pitcher that's simply always there, ready before anyone's thirsty.
Beyond the Kettle
Boricha rarely travels alone. Most versions sold in Korea today are actually blends, roasted barley mixed with corn, or sometimes gyeolmyeongja, the roasted seeds of sicklepod, a plant long used in traditional Korean herbal medicine and valued especially for eye health. On its own, gyeolmyeongja brews into a faintly sweet, mildly herbal tea, and stirred into boricha it rounds out the flavor without ever competing with the barley. Roasted corn in particular has become such a common partner that plenty of people assume it was always part of the tea. It wasn't, but it's a welcome addition if you want a milder cup: just roast a handful of dried corn kernels alongside the barley and adjust the ratio to taste.
However it's blended, boricha holds up cold better than almost any other Korean tea, which is exactly why it became the drink people reached for through the hottest months. On a humid afternoon with the air conditioner working overtime, there's something almost ceremonial about the sound of ice cracking in a glass before the tea hits it. Pour it over, and there's very little else to do.
FAQ
Does boricha have caffeine?
No. Since it's made from roasted barley rather than tea leaves, boricha has no caffeine at all, which is part of why it's served so freely to children and used as an everyday substitute for plain water in Korean households.
Can I use barley I already have at home, even if it's meant for cooking rice?
Yes. There's no strict rule requiring a specific type of barley for boricha — what matters more is the roasting. Barley meant for rice, including glutinous or specialty varieties, will still make a good tea; it just may taste slightly different from the plainer hull-on barley traditionally used.
What is gyeolmyeongja?
Gyeolmyeongja, known in English as sicklepod seed, is a small seed long used in Korean and Chinese herbal medicine, most often associated with eye health. Roasted and brewed on its own, it makes a mildly sweet, herbal tea, and it's a common partner mixed into boricha to soften the flavor.
Why is boricha so associated with that glass Delmonte bottle?
In the 1980s and 90s, Delmonte orange juice came in a thick, ridged glass bottle with a built-in grip, and once the juice was finished, the bottle rarely got thrown away. It was heavy, hard to break, and easy to hold even when wet, which made it close to ideal for refrigerator storage. Korean households refilled it constantly with boricha, so much so that it earned a nickname roughly translating to "the nation's water bottle." The bottle itself disappeared once lighter, cheaper plastic took over, but it remains a specific, shared memory for anyone who grew up with one in the fridge.
How long does homemade boricha keep?
About the same as milk — roughly a week or two in the refrigerator. Keep it in a sealed pitcher or bottle, and give it a smell before drinking if it's been sitting for a while, since a cold liquid grain tea can turn faster than water.
Is there an instant version if I don't want to roast barley myself?
Yes, tea-bag versions of pre-roasted barley are widely sold and work well for anyone short on time. Simply steep a bag in hot water, let it cool, and refrigerate. It won't have quite the same depth as home-roasted barley, but it's a fair shortcut for a daily pitcher.
