Every country has a national drink. Korea has a national drinking system, and the difference matters more than you’d think.

Spend a few days in Seoul and you’ll notice the drinks arrive with rules attached — who pours for whom, which hand does the pouring, and when you’re allowed to make eye contact with your elders. Korea has built an entire social architecture out of what goes in the glass and how you drink it.

Read the drinks correctly and you’re reading the country. Get the etiquette wrong and you may have just insulted someone’s grandfather.

And it doesn’t stop with alcohol. Coffee reflects the country’s relentless work ethic and obsession with efficiency. Tea carries centuries of tradition. Even banana milk has something to say about modern Korea.

Because in South Korea, every drink has a job to do.

Soju: The Best Selling Liquor on Earth

You’ve probably seen soju before without realizing what it was: those little green bottles that seem to be on every Korean restaurant table. What you probably don’t know is that those bottles are Jinro Soju — the best-selling liquor brand in the world.

More than Smirnoff vodka. More than Bacardi rum. More than Jack Daniels.

You get the picture. It’s popular stuff.

But the remarkable part is that outside of Korea, most of the world barely drinks soju. (Although, that may change as Korean barbecue restaurants continue to become more and more popular in the US). Koreans, on the other hand, drink absolutely heroic amounts of soju.

Traditional soju is a distilled spirit made from fermented grain, historically rice. The modern green-bottle stuff is different: it’s generally made by diluting a highly distilled neutral spirit with water and, often, sweeteners. The base alcohol can come from rice, barley, wheat, sweet potatoes, tapioca or other starches.

Soju is generally cheap, a little bit sweet, low enough in alcohol to keep pouring — and strong enough that eventually you probably shouldn’t. And it comes in approximately 31 different flavors.

That’s not a design flaw. It’s the point.

Soju isn’t designed for quiet contemplation. Nobody is swirling a green bottle under soft focus lighting and discussing its delicate finish. It’s there because drinking in Korea is a group activity.

And drinking in Korea has an organizational chart.

You pour for the person next to you. They pour for you. When drinking in front of an elder, you turn your head slightly away. Someone proposes a toast. The bottle goes around again.

Every pour acknowledges a relationship: older and younger, boss and employee, host and guest. The drink is almost incidental. It’s the exchange that matters.

Nowhere is this more obvious than at the hoesik, the Korean company dinner — a close cousin of Japan’s nomikai. Everyone leaves the office, heads to the bar, and starts passing around the green bottles.

Soju loosens Korea’s rigid boundaries of age, rank and seniority just enough for people to relax, joke, and occasionally say something to the boss that would have been a really bad idea earlier in the day.

But the hierarchy never actually disappears. Everyone may be getting progressively less capable of walking in a straight line, but they still know exactly who’s older, who’s senior, and who’s supposed to pour for whom.

Chimaek: Chicken + Maekju (Beer)

Korean beer has a reputation for being light and unremarkable, which is largely accurate. Hite, Cass and OB — the big three — are clean, cold and beer flavored. They check all the boxes.

But I think the whole point of beer in Korea might just be chimaek: chicken + maekju (beer), one of Korea’s iconic food-and-drink pairings.

If you’ve never had Korean fried chicken before, you are missing out on one of the world’s greatest foods. It’s crispier than its American cousin and often arrives with a sauce that manages to be sweet, spicy, sticky and addictive all at once.

The beer isn’t there to demand attention. It’s there to wash down another piece of fried chicken.

Somaek and Drinking Rounds

Then there’s somaek — the name is a mash-up of soju + maekju (beer), and it’s exactly what it sounds like – a beer cocktail made by mixing soju into a beer.

I mean, I mix beer with Sprite. I’m not here to judge.

Korean drinks culture approaches a night out as a series of acts: 1-cha, 2-cha, 3-cha — first round, second round, third round — moving from restaurant to bar to noraebang (karaoke bar) like a play with increasingly questionable judgment between acts. The somaek usually shows up between the rounds, which is generally a reliable sign that the evening is entering a new phase.

There is such a thing as 4-cha and beyond, but at that point the numbering system feels less informative and more cautionary.

Makgeolli: Cloudy with a Chance of Rice

Makgeolli is Korean rice wine, although it doesn’t make a particularly convincing first impression. It’s cloudy, milky-white, slightly fizzy, and has sediment at the bottom that you’re supposed to mix back in before drinking.

Basically, it ignores most of the visual cues we have collectively agreed indicate that a beverage is good to drink.

Makgeolli is one of Korea’s oldest alcoholic drinks. Unlike clear sake or wine, it isn’t fully filtered, so rice sediment remains in the liquid, giving it that milky appearance, creamy texture and slightly sweet, grainy flavor.

The fizz comes from fermentation. Traditional unpasteurized makgeolli can still contain live yeast and lactic acid bacteria, and some people swear it has gut-healthy probiotic benefits.

So it’s basically health food.

Traditionally, it’s poured from a kettle into little bowls rather than glasses. And yes, I bought the bowls.

For centuries, makgeolli was inexpensive everyday alcohol, particularly associated with farmers. There’s no elaborate glassware, no ceremony, no complicated rules about who pours for whom.

After soju’s organizational chart, makgeolli feels like casual Friday.

Korea Runs on Caffeine

If you’d asked me to name South Korea’s national beverage before visiting, I would have said soju.

And I would have been wrong. It’s iced coffee.

Everyone is carrying one. Office workers. Students. Construction workers. Retirees. People shopping. People commuting.

Korea embraced coffee relatively recently, and then, in characteristically Korean fashion, went completely overboard. Seoul is now absolutely carpeted with coffee cafés. Korea has more than twice as many coffee cafés as Starbucks has locations in the entire world.

Which makes perfect sense, because coffee may be the ideal fuel for a country that runs on ppalli-ppalli — literally quickly, quickly.

You’ll understand ppalli-ppalli approximately twelve minutes after arriving in Seoul. People walk quickly. Trains arrive quickly. Food arrives quickly. Elevators close quickly. Someone will pass you on a subway escalator while you’re already moving at a speed you personally consider ambitious.

Coffee simply joined the system.

Barley Tea & Corn Tea: The Drinks Nobody Tells You About

Although green tea is very popular in South Korea, it’s not the most popular tea. That distinction belongs to boricha (barley tea) and oksusu-cha (roasted corn tea). They’re nutty, toasty, and highly unlikely to appear on anyone’s list of the Ten Drinks You Must Try in Korea.

Which is precisely why they’re interesting.

These are the drinks of ordinary life. They show up in restaurants, homes, thermoses and refrigerators. Nobody explains it. Nobody presents it with two hands.

Barley tea (boricha) tastes exactly like what you’d expect if someone toasted a handful of barley, waved it meaningfully over a pitcher of water, and called it a beverage.

Imagine the smell of a very wholesome breakfast cereal translated into water. It tastes like something your grandmother would give you because she knows what’s good for you and doesn’t particularly care whether you enjoy it.

And then there’s corn silk tea (oksusu-suyeom-cha). Yes, corn silk. The stringy stuff you spend ten minutes picking off an ear of corn and throwing in the trash.

Korea looked at that and thought: beverage.

Corn silk tea has a distinctly corny taste. Not corn-on-the-cob-with-butter corn. More like soggy popcorn.

Neither of these teas is going to make you gasp and say, My God, what an extraordinary beverage.

And that’s the best part.

Culture isn’t only found in elaborate rituals and famous drinks. Sometimes it’s the thing nobody thinks to tell you about because nobody there thinks it’s remarkable.

Banana Milk: Pure Joy

I love banana-flavored things. Not necessarily bananas themselves, mind you. Don’t get me wrong. I like bananas just fine. But give me banana taffy, banana Runts, or Circus Peanuts — those fluffy orange marshmallow things that taste nothing like peanuts and only theoretically like bananas — and I’m in.

So when I heard about banana milk in Korea, I knew I had to track some down.

Banana-uyu is sweet, creamy, unapologetically banana-flavored and sold everywhere in a squat little plastic container that has become almost as famous as the drink itself.

There’s actually a reason it exists.

Binggrae introduced banana-flavored milk in 1974, when bananas were an expensive luxury in South Korea and the government was encouraging people to drink more milk. The solution was wonderfully straightforward: take the nutritious thing people weren’t particularly excited about and make it taste like the exotic fruit they couldn’t afford.

And it worked. Possibly too well.

Banana milk became a cultural institution. Generations of Koreans grew up drinking it. What started as a clever way to sell milk became one of those tastes permanently attached to childhood.

Naturally, I bought the silly little jar. I took a sip, and it tasted like banana candy. And it was magnificent.

To really enjoy it, you have to access the palate of your inner seven-year-old, but if you don’t do that once in a while, what’s the point?

Konjac Jelly: Water Should Not Require Chewing

While waiting in line at Olive Young to pay for an absurd amount of Korean skincare, I spotted these little Capri Sun-like pouches in a refrigerator case. At first I thought they were more skincare – refrigerated face masks seem like a totally Korean thing to do. But they were sitting next to actual drinks, so I decided they were probably edible, and bought one.

Oh my God. This was the best thing I drank in Korea.

This is konjac jelly — a strange cross between a beverage and a snack. Made with konjac, a plant-based fiber, it’s basically flavored water with slippery, chewy bits of jelly that you have to drink and eat simultaneously (I’m not really selling it, am I?). They come in flavors like apple, peach, grape and lychee. The first sip is mildly disorienting because water should not require chewing, but once you recalibrate your expectations, they are ridiculously addictive.

Since coming home, I’ve been ordering them online by the case.

Ginseng Tea: The Gift That Keeps On Coming

My dad traveled a lot when I was a kid, and trips to Korea — or trips where he was working with Koreans — inevitably meant he came home with ginseng tea. Lots of ginseng tea.

And my mother hated it.

Insam-cha (ginseng tea) isn’t necessarily something you buy for yourself. It’s something you’re given. Business partners exchange it in gift boxes. Guests bring it to hosts. It appears in the luggage of anyone who’s spent time on the receiving end of Korean hospitality. In a culture built on reciprocity, showing up empty-handed simply isn’t an option.

Dad would open his suitcase and there it would be, another beautifully packaged box of Korean ginseng tea.

Mom: Oh goodie. More ginseng tea.

At one point, I swear we had an entire closet full of the stuff. I never tried it because my mother hated it, and as a kid this seemed like enough scientific evidence that I would hate it too.

Fast-forward several decades to Shanghai, where I finally tried ginseng tea and discovered something.

I love ginseng tea.

By then, of course, my mother had long since given away our strategic reserves.

And now, whenever I drink it, I think of my mother standing over another open suitcase, wondering what on earth she was going to do with all of that ginseng tea.

That’s the thing about gifts like ginseng tea. What they signal can matter more than what’s actually in the cup. In a culture fluent in reciprocity and obligation, sometimes the drink isn’t really the gift.

The gesture is.

The Final Sip

Line these drinks up — soju’s hierarchy, makgeolli’s nostalgia, chimaek’s easy sociability, ginseng tea’s gift-giving, banana milk’s pure joy and coffee’s relentless efficiency — and a pattern starts to emerge.

None of them is really just about what’s in the glass.

That’s the thing travel guides sometimes get backwards about drinking culture. The interesting question isn’t simply, What should I order?

It’s Why is everyone drinking this?

Figure that out and the country starts to make a different kind of sense.

In Korea, that might mean turning your head when you take a shot of soju. Drinking an iced Americano while moving at a pace you previously associated with emergency evacuation. Eating fried chicken with a beer that knows its place. Or discovering, several decades too late, that you actually like the ginseng tea your mother spent years trying to get out of the house.

Pay attention to what a culture drinks, and eventually its values start showing up in the glass. Korea’s just happen to come with an organizational chart.

Geonbae! 🥂
