What Is Soju? A Guide to Korea's Little Green Bottle
You have seen the bottle. Squat, green, twist cap, usually in the middle of a Korean barbecue table or in the cooler at the Korean market. It holds the best-selling spirit brand on the planet. Jinro has topped the global spirits rankings for more than two decades, outselling every vodka, whisky, and tequila label on earth, and most of that volume is still drunk inside South Korea.
So what is soju? The short answer is a clear Korean spirit, usually 16 to 25% ABV, served cold in small glasses. The longer answer is more interesting, because one name covers two very different drinks, and the one in the green bottle exists because of a law passed in 1965. This guide covers what soju is, where it came from, how it is made, what it tastes like, and how it is drunk in Korea.
It is drawn from our free course, Soju: The Little Green Bottle, which goes deeper on every section below.
Key takeaways
Soju is a clear Korean spirit. Most green-bottle soju runs 16 to 25% ABV, well below vodka or whiskey. Traditional distilled soju can reach 45%.
One name covers two drinks. Diluted soju (huiseok) is a neutral spirit cut with water and lightly sweetened. Distilled soju (jeungryu) is pot-distilled from grain with nothing added.
The green bottle came out of scarcity. A 1965 ban on distilling soju from rice pushed producers onto a new recipe, and that recipe became the national default.
Soju is distilled and sake is brewed. Soju's closest relatives are Japanese shochu and Chinese baijiu.
It is a social drink. You pour for others, never for yourself, and it is built to be drunk with food.
What is soju?
Soju is a clear Korean spirit. The name means burned liquor (so for burn, ju for liquor), a nod to distillation, the heating step at the heart of every spirit. Traditionally it was distilled from rice or other grains, though most of it today is made a different way. What stays constant is that soju is clear, clean, and built to drink easily.
Most soju runs 16 to 25% ABV, noticeably lower than vodka or whiskey and closer to a strong wine. Traditional distilled soju is the exception and can reach 45%. In its common form it is lightly sweet and almost always served well chilled. That lower strength is a big part of why soju drinks so easily across a meal.
Two sojus, one name
The most useful thing to know about the category is that the green bottle the world drinks is a different product from what soju used to be. Get this one distinction and the rest falls into place.
Diluted soju (huiseok, 희석식) is the modern standard and almost everything sold today. It is a neutral, highly distilled ethanol cut with water and lightly sweetened. The result is clean, soft, and inexpensive, designed to disappear into a meal.
Distilled soju (jeungryu, 증류식) is the traditional style. It is pot-distilled from grain, full of aroma and character, and often bottled at 25 to 45% ABV. Think of it as a craft sipping spirit.
The green bottle is diluted soju. Traditional soju is distilled and tastes nothing like it. One name, two spirits.
A 700-year history shaped by scarcity
Soju is roughly 700 years old, and distillation came to Korea from outside. It arrived in the 13th century with the Mongols, who had picked up the technique from Persian and Arab distillers. They set up distilleries near Kaesong, the capital of the time, and in the areas around that city soju is still called arak-ju, an echo of the Arabic word arak.
Andong, in the southeast, served as a Mongol logistics base, and distilling took root there for good. Andong soju grew into a celebrated regional style: rice-based, pot-distilled, and strong, traditionally around 45% ABV. It is still made today and stands as the benchmark for traditional Korean soju. For centuries this was what soju meant: a craft product made at home or by regional specialists, varying from town to town.
Then came the hinge of the whole story. In 1965, with the country still recovering from the Korean War and rice in short supply, the South Korean government banned distilling soju from rice. Producers turned to inexpensive starches like tapioca and sweet potato, distilled them to a nearly pure neutral ethanol, then cut that ethanol with water and softened it with sweeteners. That workaround is the green-bottle soju the world drinks today.
The ban held for more than thirty years, long enough for an entire generation to grow up knowing soju only as the inexpensive green bottle. It was lifted in 1999, freeing distillers to use rice, grain, and traditional methods again. Premium distilled soju has been climbing back ever since, led by names like Hwayo and a revived Andong tradition, though the green bottle still dominates the market by a wide margin.
How soju is made
Every soju starts with starch, and the two styles take opposite routes from there. Diluted soju is built down: makers start with a nearly flavorless spirit and add things back. Distilled soju is built up: makers ferment grain and keep the flavor that distillation carries over.
Diluted soju
Starches like tapioca, sweet potato, or rice are fermented and run through a continuous column still up to roughly 95% alcohol. At that strength the spirit is almost pure ethanol, neutral by design, the same idea that sits behind vodka. It is then cut with carefully treated water down to bottling strength, and makers add small amounts of sweeteners and acidity adjusters to round off the edge. The sweeteners are there to soften high-proof spirit cut with water, and brands have been moving toward options like stevia and erythritol.
Many brands then filter through charcoal for an even cleaner taste. Chamisul is famous for a bamboo-charcoal filtration that it markets as the source of its smooth profile.
Distilled soju
The traditional route looks completely different. Grain, usually rice, is fermented with nuruk, a Korean starter packed with wild molds and yeasts that both convert starch to sugar and drive the fermentation. The flavorful mash goes through a pot still, usually just once, which keeps far more aroma, oils, and texture than a column still would. The spirit then rests before bottling, commonly at 25 to 45% ABV, with nothing added. All of the flavor comes from the grain and the still, the way it does in a good whisky.
One more production note explains the numbers on the shelf. Diluted soju once sat near 25% ABV, but competition between the big brands and changing tastes have pushed the mainstream toward 16%, with new lower-strength versions appearing almost every year.
The brands, and how to read a soju label
A soju label tells you what you need if you can find three things: the ABV, the bottle size (the 360ml single-serve bottle is the Korean standard), and the production type. That one word separates a sipping spirit from a barbecue pour.
If the label says jeungryu (증류식), it is distilled and worth slowing down for. The green-bottle standard is huiseok (희석식).
The names you will meet most often:
Chamisul. The Hite Jinro flagship and the green bottle most people picture. Filtered through bamboo charcoal and sold in a few strengths, with the popular Chamisul Fresh around 16% ABV.
Jinro. Hite Jinro's retro-styled line, which revived the company's vintage look. It leans slightly drier and crisper than Chamisul and has been a particular hit with younger drinkers.
Chum Churum. The main challenger, made by Lotte Chilsung. Marketed on alkaline water and a notably soft character, around 16 to 17% ABV.
Fruit soju. Diluted soju sweetened and flavored with peach, grapefruit, green grape, plum, or yogurt, often 12 to 14% ABV. This is how millions of newcomers first try the category.
Premium distilled soju. Hwayo is the best-known modern example, rice-based and sold at several strengths. Andong Soju carries the old regional name, and craft producers like Tokki have taken distilled soju onto international back bars.
What soju tastes like
Classic green-bottle soju is built to be easy. It is clean and clear, lightly sweet, with a soft mouthfeel and very little aroma. Its job is to refresh the palate between bites of rich, spicy, grilled food, so judge it on smoothness and drinkability. Served ice cold in a small glass, it is gently warming and almost neutral. Let it warm up and the rough edges show, which is why it is almost always poured chilled.
Fruit soju leans into sweetness and approachability. The flavored versions taste more like a soft cooler than a spirit, and at 12 to 14% ABV they drink closer to wine in strength.
Premium distilled soju is a different sensory experience. Because a pot still carries character over from the fermented grain, it shows real aroma: floral, nutty, sometimes a clean rice sweetness, with a fuller texture and a long finish. Serve it only barely chilled, or even at room temperature, so those aromas can open up. Tasting it next to a green bottle is the fastest way to understand the gap between the two styles.

Soju vs sake, shochu, baijiu, and vodka
Soju is constantly confused with its neighbors. Sake is Japanese and brewed from rice, closer to beer in how it is made, and Korea has its own brewed rice drinks in cloudy makgeolli and clear cheongju. Soju is distilled, or built from distilled alcohol, which puts it in a different family. Our guide to reading a sake label covers the brewed side.
Shochu is the closest cousin: Japanese, single-distilled from barley, sweet potato, or rice, unsweetened, and usually about 25% ABV. Premium distilled soju lands close to it in both spirit and intent. Baijiu is the Chinese distillate, with a far bolder flavor profile, and we cover it in our baijiu primer.
Vodka is the most useful reference point for the green bottle. Vodka is neutral, strong at around 40% ABV, and unsweetened. Diluted soju is built the same way and bottled gentler, so it drinks like a softer, sweeter, lower-proof relative. That is why soju slots so naturally into vodka cocktails at a lighter strength. Our vodka guide covers how base material and texture shape that category.
How soju is drunk in Korea
Soju is social before it is anything else, and the pouring is the ritual that carries the evening. The first rule is simple: you never pour your own glass. You fill your neighbor's, they fill yours, and the bottle moves around the table all night.
When you pour for someone older or more senior, hold the bottle with your right hand and support your forearm or the bottle with your left. Receiving follows the same logic: take the glass in both hands, and on that first glass turn your head slightly to the side as you sip. Among close friends of the same age the rules relax, but the two-handed pour is never wrong.
The glasses are small, around 50ml, closer to a shot than a wine pour. That size is deliberate. It keeps the bottle moving and the ritual going, because an empty glass is an open invitation for a neighbor to fill it.
Never pour your own glass. You fill your neighbor's and let them fill yours. The whole table notices.
Somaek
The most famous soju mix is somaek, a blend of soju (so) and beer (maekju). A common ratio is about one part soju to three parts beer, which lightens the soju into an easy-drinking round that carries a meal. It is as much a performance as a drink, and the shared round matters more than any precise measure.
Food and anju
Soju is a food drink to its core, and the food it is drunk with even has its own name: anju. Its clean, slightly sweet, lower-proof profile cuts through fat, salt, and chili, so it sits naturally beside Korean barbecue, fried chicken, spicy stews, and seafood. Pair by contrast and refreshment, letting the soju reset the palate between rich bites.
Four easy soju drinks
Soju mixes well because it is light and clean. A few simple builds show it off:
Somaek. Soju topped with cold lager, about one part soju to three parts beer.
Yogurt Soju. 2 oz (60 ml) soju, 3 oz (90 ml) Korean yogurt drink, 2 oz (60 ml) lemon-lime soda, over ice. The one that wins over almost any first-timer.
Watermelon Soju (subak-ju). 3 oz (90 ml) fresh watermelon juice and 2 oz (60 ml) soju over ice. The group showpiece, often served straight from a hollowed-out melon.
Cucumber Soju Highball. 1 1/2 oz (45 ml) soju, 4 oz (120 ml) soda water, 3 cucumber slices, over ice. Clean enough to let a good soju show.
One storage note: keep opened soju in the fridge and use it within a few weeks. There is no aging benefit, and chilled is how the category is meant to be poured.
Why you are seeing more soju in the US
Korean barbecue, K-pop, and K-dramas put the green bottle in front of new drinkers every year, and North American demand has been climbing with them. Soju also fits the broader move toward lighter, more sessionable drinks, a shift we track in our 2026 alcohol industry trends and in what Americans are drinking instead of alcohol.
There is also a licensing reason soju turns up on menus at restaurants that do not serve liquor. In some states, lower-strength soju is grouped with beer and wine.
California. Business and Professions Code section 23398.5 lets any on-sale license that authorizes the sale of wine also sell soju at not more than 24% ABV, and since January 1, 2025 that covers domestically produced soju as well as imported Korean soju.
New York. Alcoholic Beverage Control Law section 81 says a restaurant wine license includes the right to sell beer, soju, and shochu, with soju defined as an imported Korean beverage of not more than 24% ABV.
That is why you find soju cocktails at beer-and-wine restaurants in those states, and part of why mainstream soju stays well under that line. Rules differ by state and change over time, so check your own state regulator before relying on any of this.
Soju FAQ
Is soju the same as sake?
No. Sake is Japanese and brewed from rice. Soju is Korean and distilled, or built from distilled alcohol. Its closest cousin is Japanese shochu.
How strong is soju?
Most green-bottle soju runs 16 to 25% ABV, and the big brands now sit around 16 to 17%. Fruit soju is lower, often 12 to 14%. Traditional distilled soju runs 25 to 45%.
What is soju made from?
Green-bottle soju starts as a neutral spirit distilled from starches like tapioca, sweet potato, or rice, which is then cut with water and lightly sweetened. Traditional distilled soju is made from grain, usually rice, fermented with a Korean starter called nuruk and run through a pot still.
What is the difference between soju and shochu?
Shochu is Japanese, single-distilled from barley, sweet potato, or rice, unsweetened, and usually about 25% ABV. Green-bottle soju is a diluted neutral spirit that is lightly sweetened. Premium distilled soju is the style that comes closest to shochu.
How do you drink soju?
Cold, in small glasses, with food, and with other people. Pour for your neighbors and let them pour for you. Use two hands when pouring for or receiving from someone older. Premium distilled soju is the exception on temperature: serve it barely chilled or at room temperature.
