Soju vs. Shochu: What’s the Difference?Soju and shochu are two distilled spirits from East Asia that are often compared because of their similar names, overlapping histories, and shared cultural roles as everyday liquors. Although they may seem interchangeable at first glance, they differ in ingredients, production methods, flavor profiles, alcohol content, cultural context, and how they’re typically consumed. This article breaks down those differences and explains how each spirit fits into its country’s food culture and global cocktail scene.
Origins and history
Soju
- Origin: Korea. Soju’s roots trace back to the 13th–14th centuries when distillation technology came to Korea from the Middle East via Mongol and Persian influences.
- Historical context: Once a household-made spirit, modern soju became industrialized in the 20th century, especially after rice shortages during and after the Korean War led producers to substitute other starches and begin large-scale production.
- Cultural role: Soju is a ubiquitous, affordable daily-drinking spirit in Korea, commonly consumed with meals and at social gatherings.
Shochu
- Origin: Japan, primarily associated with Kyushu (e.g., Kagoshima, Miyazaki). Distillation in Japan is believed to have begun around the 16th century, influenced by techniques from the Asian continent.
- Historical context: Shochu has long regional variations tied to local ingredients and traditions. It remained more of a regional specialty until broader interest and marketing increased national consumption.
- Cultural role: Shochu occupies a versatile role — from casual home drinking to premium artisanal bottles — and is often paired with specific regional dishes.
Ingredients
Soju
- Traditional base: Historically made from rice, wheat, or barley.
- Modern variants: Many mass-market sojus use cheaper starches such as sweet potato, tapioca (cassava), or other grains. Some premium brands have returned to rice or use multiple grains.
- Flavor impact: Neutral grain bases lead to a relatively clean, mild flavor that is easy to mix with fruit juices and cocktails.
Shochu
- Common bases: Sweet potato (imo), barley (mugi), rice (kome), buckwheat, and even sugar cane or chestnut in some locales.
- Single-origin focus: Many shochu are labeled by their base ingredient (e.g., imo shochu), and that ingredient strongly influences aroma and taste.
- Flavor impact: Shochu’s character ranges from earthy and robust (sweet potato) to smooth and cereal-like (barley) or delicate and clean (rice).
Production methods
Soju
- Distillation: Historically distilled, but most mass-market soju is now made by dilution of distilled ethanol with water and flavoring agents (a process similar to making neutral spirit-based liqueurs). Some premium soju are genuinely distilled from fermentations.
- Fermentation: When distilled traditionally, soju begins with a fermented mash of grains or starches.
- Filtration and smoothing: Many producers filter the spirit and add sweeteners or flavor enhancers to create a smooth, approachable product.
Shochu
- Distillation: Typically produced by single or double pot still distillation from fermented mash, preserving more of the base ingredient’s character.
- Koji use: Shochu fermentation often relies on koji mold (Aspergillus oryzae), which saccharifies starches into fermentable sugars — the same basic process used for sake and miso — but with different strains and techniques.
- Aging: Some shochu are aged in tanks, clay pots, or wooden casks; aging can add complexity and mellowness.
Alcohol content and labeling
- Soju: Most commercial soju ranges from 12% to 24% ABV, with many popular brands clustered around 16–20% for the mainstream market. Low-alcohol (8–12%) flavored sojus also exist.
- Shochu: Generally higher on average, commonly ranging from 25% to 30% ABV, though variations exist — some are bottled at 20% and others can be much stronger.
Labeling differences
- Soju labels often emphasize brand and flavor; some premium sojus will specify ingredients or single-origin rice.
- Shochu labels commonly specify the base ingredient (imo, mugi, kome), the distillation method, and sometimes the koji strain or region.
Flavor profiles
Soju
- Profile: Clean, neutral, slightly sweet or grainy, and very smooth—especially the mass-produced varieties.
- Versatility: Because of its neutral flavor and lower ABV range, soju is easy to drink straight, mix with soda or juices, and use in cocktails.
Shochu
- Profile: Wide range depending on base:
- Imo (sweet potato): earthy, fruity, sometimes savory with a distinct aroma.
- Mugi (barley): nutty, cereal-like, mild.
- Kome (rice): clean, delicate, sake-like.
- Complexity: Shochu tends to present stronger, more distinct base-driven flavors than mainstream soju.
Serving traditions and pairings
Soju
- How it’s served: Typically served chilled or at room temperature in small shot glasses; communal pouring and drinking rituals are important in Korea (pouring for elders, two-handed offers, accepting with two hands).
- Food pairings: Korean barbecue, spicy stews (jjigae), and savory anju (drinking snacks). Soju’s clean profile complements strong, spicy, and fatty foods.
Shochu
- How it’s served: Enjoyed neat, on the rocks, diluted with hot/cold water (oyuwari/mizuwari), or with soda. Serving temperature varies by type — some are warmed, some chilled, some with hot water to release aromas.
- Food pairings: Regional Japanese cuisine — grilled fish, sashimi, yakitori, and heavier or rustic dishes depending on shochu type. Shochu’s diversity allows intentional pairing with specific ingredients.
Price and market positioning
- Soju: A dominant mass-market presence in Korea; many brands are very affordable. Premium and artisanal sojus exist but are less common globally.
- Shochu: Strong regional artisan tradition; price varies widely. Some high-quality, aged, or single-ingredient shochu can be premium-priced and collected.
Cocktails and mixability
Soju
- Cocktails: Extremely cocktail-friendly due to lower ABV and neutral flavor. Popular mixed drinks include soju with fruit juices, the soju bomb (soju dropped into beer), and flavored soju spritzers.
- Modern trends: Flavored sojus (peach, grapefruit, yogurt) have expanded its appeal, especially to younger drinkers.
Shochu
- Cocktails: Used in cocktails that highlight its character or in simple highballs and chu-hai-style drinks. Bartenders may substitute shochu for vodka/gin to add unique base notes.
- Traditional mixes: Mizuwari (with cold water), oyuwari (with hot water), with oolong tea, or with soda.

| Flavor | Neutral, smooth, slightly sweet | Wide range: earthy, nutty, delicate |
| Serving | Shots, chilled; communal rituals | Neat/rocks, mixed with water/soda; temperature varies |

How to choose between them
- For neutral, easy-drinking, and cocktail use: choose soju.
- For distinct, ingredient-driven flavors and sipping with specific foods: choose shochu.
- For lower alcohol: soju typically. For stronger, more flavor-forward spirit: shochu typically.
Try this tasting approach
- Choose one rice-based soju and one rice-based shochu to keep the base consistent.
- Serve each at the recommended temperature: chilled for soju; room temperature or slightly warmed for shochu depending on label guidance.
- Take small sips, note aroma, mouthfeel, sweetness, and finish. Repeat with an imo (sweet potato) shochu to experience a bolder contrast.
- Pair each with small bites: plain grilled meat for soju; grilled mackerel or pickled vegetables for shochu.
Closing note
Though soju and shochu share historical links and a common place at the table, they are distinct spirits with different traditions, production techniques, and flavor identities. Understanding those differences makes it easier to choose the right bottle for cooking, mixing, or sipping.
