The names sound related because they are. But soju and somaek are different things: one is a Korean alcoholic drink, and the other is a mixture that includes it.
If you are exploring Korean drinks for the first time, that small distinction makes menus, recipes and conversations much easier to follow.
The difference at a glance
| Question | Soju | Somaek |
|---|---|---|
| What is it? | A Korean alcoholic drink | Soju mixed with beer |
| Does it contain beer? | No beer is required | Yes |
| Can its flavor vary? | Yes, depending on the product | Yes, depending on both drinks and their proportions |
| Does the name specify alcohol strength? | No; check the bottle | No; it depends on both ingredients and the ratio |
Soju is the ingredient

Soju can be enjoyed on its own or used in a mixed drink. There are plain and fruit-flavored products, and bottles differ in their flavor and alcohol content.
That means “soju” is a useful starting description, but the label still matters. Check the particular product rather than assuming all bottles taste the same or have the same strength.
Our What Is Soju? guide explores the drink, its background and the differences between plain and fruit varieties.
Somaek is the combination
Somaek brings soju and beer together. The name combines soju with maekju, the Korean word for beer.
The beer contributes its own flavor and carbonation, while the soju and the proportions influence the finished mixture. Changing either bottle can change the experience even when your measurements stay the same.

Is somaek stronger than soju?
There is no single alcohol percentage for either category. The answer depends on the products you use.
When the beer has a lower alcohol percentage than the soju, combining them lowers the mixture’s alcohol concentration compared with that soju alone. It does not remove the alcohol you poured, and a larger drink can contain more total alcohol than a smaller one.
For a practical example, imagine soju labeled 16% ABV and beer labeled 5% ABV. At a 1:3 ratio, the approximate combined strength is 7.75% ABV, before any additional dilution. These are example label values, not a claim about every bottle.
The important distinction is between concentration and amount. Read the labels, choose the quantity you want and enjoy at your own pace.
Can you use fruit soju in somaek?
Yes. It changes the flavor of the mixture, so treat it as a different version rather than expecting the same result as plain soju.
When exploring a new combination, make a modest measured pour. Keep track of the bottles and proportions you chose so you can repeat a balance you enjoy.
Which one belongs in a somaek glass?

Somaek inspired our name, but the glass is yours to enjoy with your favorite beverage. For a soju-and-beer mix, Large Somaek’s soju guide lines on the back help you measure your starting pour. Add the matching amount of beer for your chosen ratio, and you can make your perfect mix every time.
The markings do not determine the finished ratio by themselves. You also need to know how much beer you add. Our ratio guide walks through that process.
