When most people ask “what soju,” they’re implicitly asking about the clear, slightly sweet, low-alcohol spirit that dominates Korean drinking culture. The easy, direct answer is that soju is Korea’s national spirit, a clear distilled beverage typically ranging from 16% to 25% ABV, made most commonly from starches like tapioca, sweet potato, or rice. While traditional, premium soju can be a complex, higher-proof spirit, the soju you’re most likely to encounter in any bar or grocery store worldwide, like Chamisul or Chum Churum, is a diluted, neutral-tasting product designed for mass appeal and easy drinking.
Defining What Soju Really Means
The question “what soju” carries more weight than it seems because the term encompasses two distinct categories, much like how “whiskey” can mean a cheap blend or a single malt. Most of the time, when soju is mentioned, it refers to:
- Diluted Soju (Chamisul, Chum Churum, etc.): This is the dominant form, a neutral spirit produced from various starches, distilled, and then diluted with water to a lower alcohol percentage. It’s often filtered through bamboo charcoal for a clean finish and sometimes has a touch of added sweetness.
- Traditional Distilled Soju (Andong Soju, Hwayo, etc.): This is the craft, often artisanal version. Made exclusively from fermented rice or other grains, it’s distilled to a higher proof (often 25% to 45% ABV or more) and can carry complex aromas and flavors, sometimes aged in earthenware. It’s less common but represents the historical roots of the spirit.
The Soju You’ll Most Likely Encounter: Diluted Soju
For the vast majority of drinkers, soju means the clear, relatively low-proof bottles that line the shelves of Korean restaurants and Asian markets. Brands like Jinro’s Chamisul Fresh (around 17% ABV) or Lotte Chilsung’s Chum Churum Original (around 16.5% ABV) are the global ambassadors of soju. These spirits are designed to be smooth, easy to drink, and pair well with food, particularly the rich flavors of Korean cuisine. They are typically served chilled, often neat, or as the base for various cocktails.
What Soju Isn’t (Common Misconceptions)
Many people have a simplified or even incorrect understanding of soju. Here are a few things to clarify:
- It’s Not Always Rice-Based: While rice was traditionally the primary ingredient, government regulations during the Korean War era led to the use of other starches like tapioca, sweet potato, and wheat. Today, many mass-market sojus use a blend of these.
- It’s Not Always “Strong”: Compared to typical Western spirits like vodka or whiskey (which are 40% ABV+), the most popular soju brands are significantly milder, often in the 16-20% ABV range. This makes them more akin to a strong sake or a fortified wine in terms of alcohol content.
- Flavored Soju Isn’t the Original: The explosion of fruit-flavored sojus (grapefruit, peach, strawberry) is a relatively recent phenomenon, popularizing soju among younger drinkers. These are usually diluted sojus with added flavorings and often an even lower ABV, typically around 12-14%. They are not representative of traditional soju.
- It’s Not Just a Shot Drink: While shots are common, especially in drinking games, soju is often enjoyed slowly, neat, alongside food, or mixed into popular Korean drinking rituals like the Somaek (soju and beer mix).
The Other Side of Soju: Traditional & Premium Distilled Varieties
For those seeking a more refined experience, traditional distilled soju offers a different world. These are handcrafted, often from 100% rice, using ancient methods. Brands like Andong Soju, Hwayo, or Moonbaesool offer a much higher proof (from 25% up to 45% or more) and exhibit complex flavors—often nutty, floral, or even earthy notes. They are typically enjoyed neat and savored, much like a fine whiskey or brandy. These premium sojus are harder to find outside of Korea or specialist liquor stores but provide a truer glimpse into the spirit’s rich heritage.
How to Enjoy Soju
The most common way to enjoy soju is chilled, in small shot glasses, often shared among friends. It’s almost always consumed with food, particularly Korean BBQ, stews, and a variety of banchan (side dishes). The low-key flavor profile of diluted soju makes it an excellent companion that cleanses the palate without overpowering the meal.
Final Verdict
When you ask “what soju,” the answer you’ll most often encounter is the clear, mildly sweet, diluted spirit like Chamisul or Chum Churum, typically around 16-20% ABV. For a deeper, more traditional experience, seek out a premium distilled soju. The takeaway: soju is more than just a shot; it’s the versatile cornerstone of Korean social drinking.
