Walk into any Korean convenience store and you’ll see rows of identical small green bottles, along with a growing rainbow of fruit-flavored ones: grapefruit, green grape, plum, peach, and more. If you’re curious about soju flavors, that shelf is the perfect place to start.
Soju is Korea’s best-known spirit, but for many visitors it raises simple questions. What exactly is it? Why are almost all the bottles green? How is a grapefruit soju different from the classic one? And when do Koreans actually drink it?
This guide answers those questions with a focus on culture rather than shopping: where soju came from, why the green bottle became a national standard, how fruit soju appeared and who it was made for, how Koreans pair soju with food, how drinking habits are changing among younger Koreans, and what first-time visitors should know to enjoy it comfortably and responsibly.

What Is Soju?
Soju is a clear Korean spirit, usually served cold in small glasses. Its roots go back roughly 700 years, when the technique of distillation reached Korea, and traditional distilled soju made from grains such as rice is still produced today, typically at 25 to 45 percent alcohol. But the soju most people know, the one in the small green bottle, is a different product. Green-bottle soju is a diluted spirit: it starts as a neutral spirit distilled from starches such as tapioca, sweet potato, or rice, which is then cut with water and lightly sweetened.
Its history was shaped by scarcity. In 1965, a national rice shortage led the government to ban the use of rice for making alcohol, and the ban lasted for more than thirty years. Manufacturers switched to other starches and to the diluted style, and an entire generation grew up knowing soju only as an inexpensive green bottle.
The alcohol content has also changed dramatically. The first commercial soju brand, launched in 1924, was 35 percent alcohol. Through the 1990s, around 25 percent was standard, but competition between the big brands and changing tastes have steadily pushed it down, and in 2026 mainstream green-bottle soju sits at around 16 to 17 percent.
Soju remains one of Korea’s most important drinks, even though Koreans drink more beer by volume. Part of the reason is its price; a standard bottle has long been one of the cheapest drinks in any Korean convenience store. That accessibility is why soju shows up at nearly every kind of gathering, from family dinners to after-work meals with coworkers.
Why Are Soju Bottles Green?
Soju wasn’t always green. In the past, producers bottled it in whatever glass they liked, so bottles ranged from white to brown to blue. That changed in 1994, when Doosan Beverage, a company later acquired by Lotte Chilsung, launched the first soju in a green bottle. The color was chosen to signal a clean, smooth, mild taste, and it was a marketing hit. Competitors soon switched to green bottles of their own. The story then turned from marketing to recycling.
As more brands used similar green bottles, producers realized they could save money if every company used the same bottle. In 2009, seven major soju companies, including HiteJinro and Lotte Chilsung Beverage, made a voluntary agreement with Korea’s Ministry of Environment to use a standardized green bottle. Any bottle could then be collected and reused by any producer, whichever brand originally filled it. If you look closely at an empty bottle, you might even notice another company’s name embossed on the glass.
The results have been impressive. In 2020, about 97.9 percent of soju bottles were collected, one of the highest recovery rates for any beverage container in the world. That’s a nice connection to Korea’s wider recycling culture. There are exceptions. The retro brand Jinro Is Back stepped outside the standard with a light blue bottle, and premium and traditional soju come in all kinds of designs. The toad on the Jinro Is Back label is the brand’s decades-old mascot, brought back with the 2019 retro relaunch. But for most people, the small green bottle remains the instant symbol of soju.
Soju Flavors: Classic vs. Fruit, and Why Grapefruit Became a Thing
Classic green-bottle soju has a clean, neutral, slightly sweet taste, with a noticeable alcohol bite. It’s designed to go with food, and on its own many first-timers find it sharper than expected. Fruit soju changed that. In March 2015, Lotte Chilsung Beverage launched Soonhari, a citron-flavored soju at 14 percent alcohol, described as a new kind of “soju cocktail.” It quickly became a hit, and competitors rushed to release their own versions.
Why did it appear? Part of the answer is a change in who was drinking. More women were joining the workforce and taking part in after-work gatherings, and research by Lotte found that many were reluctant to drink soju or beer because of the high alcohol content and bitter taste. More broadly, younger drinkers were looking for milder drinks they could sip and enjoy, rather than strong liquor that simply gets you drunk. Fruit soju answered both needs.
Today, the lineup of soju flavors includes grapefruit, green grape, plum, peach, apple, strawberry, and yogurt, typically at 12 to 14 percent alcohol, lower than classic soju. Grapefruit is one of the most popular fruit flavors, with a bright citrus taste.
The domestic boom cooled after the mid-2010s, but fruit soju found a second life abroad, where Korean producers have been selling more flavored soju to overseas drinkers. Back home, the next wave has been “zero sugar,” which took off after Lotte launched Saero in 2022. One important caution: because fruit soju tastes sweet and mild, it’s easy to drink faster than you realize, even though it still contains far more alcohol than beer.
When Koreans Drink Soju, and Why Food Always Comes With It
In Korea, soju is rarely enjoyed on its own. It’s a drink for the table. Koreans pair soju with anju, food meant to be eaten with alcohol, and the classic matches are rich, salty, or spicy dishes such as Korean barbecue, stews, and raw fish. That food-first approach is one of the biggest cultural differences visitors notice. As one industry official told The Korea Herald, overseas customers tend to enjoy alcoholic drinks by themselves or with finger foods, while Koreans usually pair soju with various dishes. Traditionally, soju has also been tied to Korean social life, from family celebrations to after-work gatherings with colleagues.
For decades, company dinners called hoesik involved plenty of soju, and joining in was seen as part of building relationships at work. Today, those habits are changing quickly. Younger Koreans are drinking less and choosing lighter soju flavors and lower-alcohol drinks that fit more health-conscious lifestyles, and the traditional drinking culture that once seemed essential for workplace relationships is gradually losing influence. Major brands have lowered their alcohol content to around 16 percent, and zero-sugar options have spread.
Health is a big part of this shift, and many younger Koreans now put exercise and wellness ahead of long nights out. Social gatherings haven’t disappeared, though; they’ve diversified. Many Koreans meet through hobby clubs and interest groups that start online and continue offline, where soju may be on the table but is no longer the main event. For visitors, that means you’ll see both sides of Korea: lively soju-filled tables at neighborhood restaurants, and a younger generation that’s comfortable choosing lighter drinks or none at all.
Soju Etiquette and First-Timer Tips, and How It Compares With Drinking in the U.S.
If you drink soju with Koreans, a few customs go a long way. Hold your glass with both hands when a senior pours for you. Pour for others rather than yourself. You turn your face to the side as a sign of respect — it avoids drinking face-to-face with a senior. Our guide to Korean drinking culture covers these customs in more detail. For first-timers, a few practical tips help. Start slowly. Soju is usually served in small glasses, and there’s no need to keep up with anyone; sipping is perfectly fine. Always eat while you drink; soju is meant to be paired with food. Drink water between glasses. Be extra careful with fruit soju, whose sweetness can hide how strong it is. And remember that it’s perfectly acceptable in today’s Korea to decline a drink, especially if you explain politely, or to fill your glass with a soft drink. A simple phrase like “jeoneun suri yakhaeyo,” meaning “I don’t drink much,” is understood everywhere. For American visitors, the biggest difference is context. In Korea, drinks are almost always served with food, called anju, and the food is part of the experience. In Korea, soju is shared by the bottle at a restaurant table, poured into small glasses for one another, and enjoyed alongside a full meal. The drink is a way to connect, not the destination. Whether you choose a classic green bottle, a grapefruit soju, or a soft drink, the most important part of the experience is the same: the food, the conversation, and the people around the table.
Frequently Asked Questions (FAQ)
Is soju the same as vodka?
No. Both are clear spirits, but green-bottle soju is much lower in alcohol, usually around 16 to 17 percent compared with about 40 percent for vodka, and it’s lightly sweetened.
How big is a bottle of soju?
A standard green bottle holds about 360 milliliters, roughly half the size of a standard wine bottle, and it’s usually shared by everyone at the table.
Why do some soju bottles look blue?
A few brands, such as the retro Jinro Is Back, use a light blue bottle instead of the standard green one. Premium and traditional soju also come in their own bottle designs.
Is traditional soju different from green-bottle soju?
Yes. Traditional soju is distilled from grains such as rice and is usually much stronger, around 25 to 45 percent alcohol, with a fuller, more complex flavor — a very different experience from the mild modern soju flavors.
My Take
A lot of my friends in Korea drink soju after work. They get together, talk, and form groups to go out, and there are so many hobby clubs. It seems like the culture of chatting online and then meeting offline to drink and have fun is really well developed. I was surprised when one friend told me he’s in eight different groups. He said they don’t all meet every week, but honestly, with a full-time job, wouldn’t eight groups be exhausting?
For my generation, soju feels like just part of everyday life, but when I hear about how the younger generation drinks, I think they’re the wise ones. I’m not a strong drinker myself, so I usually drink fruit soju, and watermelon soju is my favorite of all the soju flavors.
