What Is Soju? A Comprehensive Guide

Soju, a cornerstone of Korean culture, is rapidly gaining popularity worldwide, making it a lucrative addition to any restaurant, bar, or retail establishment. South Korea is the largest producer and consumer. Jinro Soju, a leading brand, has consistently been the world's best-selling spirit by volume. The increasing interest in Korean cuisine and culture worldwide, driven by phenomena such as K-pop and Korean dramas, has significantly boosted soju's presence in international markets.

Understanding soju and its appeal can help business owners tap into this growing market. Offering soju can attract a diverse clientele, including those familiar with Korean culture and those curious to explore new and exotic beverages.

But what is soju?

By comprehensively understanding soju, restaurants, bars, and small business owners can effectively incorporate this versatile spirit into their offerings, enhancing the customer experience and tapping into a vibrant and expanding market. This guide will explore the history, production, types, cultural significance, and practical aspects of incorporating soju into your business offerings.

What Is Soju?

So, what is soju? At its core, soju is a clear, distilled spirit that originates from Korea. Its alcohol content generally ranges from sixteen percent to twenty-five percent, positioning it between lighter beers and more potent liquors like vodka. Soju's defining characteristic is its mild flavor and subtle sweetness, making it incredibly versatile for drinking straight and mixing into cocktails.

Soju's unique characteristics stem from its production process and ingredients. Unlike vodka, known for its neutrality, soju retains a slight sweetness and a smooth texture, partly due to using different starches and sometimes added sweeteners.

Other defining characteristics include:

  1. Alcohol Content: Traditional soju tends to be on the higher end of this spectrum, while diluted soju is usually around twenty percent or lower. This makes soju accessible to a wide range of consumers, from those who prefer stronger spirits to those who enjoy lighter drinks.
  2. Flavor Profile: The flavor profile of soju can vary significantly depending on the ingredients and production methods used. Traditional soju often has a richer, more robust flavor, while modern diluted soju is lighter and sometimes slightly sweet due to added sugars.
  3. Versatility: Soju's mild flavor makes it highly versatile. It can be enjoyed neat, on the rocks, or as a cocktail base. Its lower alcohol content compared to many distilled spirits also makes it a popular choice for social drinking.

The History of Soju

Understanding what soju is requires delving into its rich and storied history, which spans several centuries and reflects Korea's dynamic cultural and historical shifts. The evolution of soju is a testament to the resilience and adaptability of Korean culture, as well as the spirit's deep-rooted significance in Korean society.


The history of soju begins in the 13th century during the Goryeo Dynasty (918-1392). Mongol invaders, who had learned distillation techniques from the Persians, introduced these methods to Korea during this period. The Mongols used arak, a distilled spirit, as a base, which they adapted using local Korean ingredients.

Initially used for medicinal purposes, soju became a popular beverage deeply embedded in Korean culture. Familiarizing yourself with this rich history can enhance your storytelling when presenting soju to your customers.

Understanding what soju is also means recognizing its cultural significance. In Korea, soju is more than just a drink; it is a social ritual and a symbol of hospitality. It is commonly consumed during meals, celebrations, and social gatherings. Soju is often shared among friends and family, with specific customs such as pouring drinks for others and receiving them with both hands as a sign of respect. Incorporating these cultural aspects into your service can give your customers a more authentic and engaging experience.

How Is Soju Made?

Traditional soju is primarily made from rice, but the modern production process often incorporates a variety of starches, including wheat, barley, potatoes, sweet potatoes, and tapioca. This shift began during the Korean War when rice shortages prompted the use of alternative starches. The primary steps in soju production are fermentation, distillation, dilution, and sometimes flavoring.

  1. Fermentation: The chosen starches are mixed with water and fermented using yeast and nuruk (a traditional Korean fermentation starter) to convert the starches into sugars and then into alcohol.
  2. Distillation: To increase the alcohol content, the fermented mixture is then distilled using a pot still, which results in a richer and more complex flavor. Modern methods may use continuous stills for greater efficiency and consistency.
  3. Dilution: The high-proof spirit is usually diluted with water to achieve the desired alcohol content. This step is especially prominent in producing diluted soju, popular in contemporary markets for its lower alcohol content and lighter taste.
  4. Flavoring: Some soju varieties are flavored with fruit essences or other additives to cater to different palates. Popular flavors include peach, apple, and grapefruit.

Different Types of Soju

Understanding the various types of soju is essential for effectively incorporating this popular Korean spirit into your restaurant, bar, or retail offerings. The diversity in soju's production methods, ingredients, and flavors means there is something for every palate, providing an excellent opportunity to cater to a wide range of customers.

Traditional Soju

Often referred to as "Andong soju," this type of soju is rooted in centuries-old methods. It is known for its higher alcohol content, typically around forty-five percent, and its rich, complex flavor profile.

Diluted Soju

The most common type in the market today, is characterized by its lower alcohol content and smoother taste. This type of soju appeals to a broader audience, including those who prefer lighter spirits. 
Flavored Soju: This type has gained immense popularity, especially among younger consumers and those new to soju. These variations infuse the traditional spirit with fruit flavors and other essences to create a sweeter and often more accessible beverage.

Premium Soju

Premium soju represents the high-end segment of the market, focusing on quality ingredients, traditional methods, and unique flavors. These sojus are often marketed as artisanal products and can command higher prices.

How Does Soju Compare to Other Spirits?

When comparing soju to other spirits, its closest counterpart is vodka due to its clear appearance and similar use in cocktails. However, soju differs significantly in flavor and cultural context:

  • Vodka: Known for its neutrality and high alcohol content (typically forty percent), vodka is a staple in many Western cocktails. In contrast, soju's milder flavor and lower alcohol content make it more approachable for casual drinking.
  • Sake: Often confused with soju, sake is a Japanese rice wine with a completely different production process. Sake is brewed like beer, while soju is distilled like vodka. Sake generally has a lower alcohol content (around fifteen percent) and a distinct flavor profile that is less versatile for mixing.
  • Shochu: This Japanese spirit is perhaps the closest relative to soju, as it is also a distilled beverage made from various starches. Shochu can have a wide range of alcohol content and flavor profiles, much like soju, but it is typically less sweet and can be stronger.

How to Serve Soju

Understanding soju extends beyond its history and production; it encompasses the art of serving this iconic Korean spirit. Properly serving soju not only enhances the drinking experience but also honors its cultural traditions. For restaurants, bars, and small business owners, mastering the etiquette and techniques of serving soju can significantly elevate your service and create a memorable customer experience.

Traditional Serving Etiquette

In Korean culture, soju is often consumed in a communal setting, and how it is served and consumed is imbued with cultural significance. Here are some critical points of traditional soju etiquette:

  1. Pouring for Others: One of the most important aspects of serving soju is the custom of pouring for others rather than oneself. This practice fosters a sense of community and respect. When pouring soju for someone else, use both hands to hold the bottle. If you're the recipient, grab your glass with both hands or at least your right hand while supporting your wrist with your left hand.
  2. Receiving a Drink: When someone pours soju for you, accepting it with both hands is polite. This gesture signifies respect and gratitude. After receiving the drink, waiting until everyone in the group has been served before drinking is customary.
  3. First Drink: Traditionally, the first drink of soju is often consumed in one go as a shot. This is especially true in formal or celebratory settings. After the first round, subsequent drinks can be sipped more leisurely.
  4. Toasting: Toasting is an integral part of the soju-drinking experience. The most common toast is "Geonbae" (건배), which means "cheers." When toasting, it’s respectful to clink glasses at a lower level than your seniors or superiors.
  5. Refilling Glasses: It’s considered polite to refill others’ glasses when empty to ensure that no one’s glass remains empty for long. However, never pour your drink; it’s a communal activity where everyone cares for each other.

Serving Temperature

Soju is typically served chilled, which helps to enhance its smoothness and subtle flavors. Here are some guidelines for serving soju at the right temperature:

  1. Chilled Soju: Most soju varieties are best enjoyed cold. Store bottles in the refrigerator and serve them straight from there. Chilled soju is refreshing and smooth, making it an ideal choice for many occasions.
  2. Room Temperature Soju: While less common, some traditional or premium soju may be served at room temperature to allow their more complex flavors to be fully appreciated. If serving soju this way, ensure the environment is cool and comfortable.
  3. On the Rocks: Although not traditional, some people enjoy soju over ice, which slightly dilutes the alcohol, making the drink even more refreshing, particularly on a hot day.

Serving Vessels

The choice of serving vessels can also impact the soju experience. Here are the types of glasses typically used:

  1. Soju Shot Glasses: Small, typically holding around 50 ml, these glasses are the standard for serving soju. Their size encourages moderation and frequent toasts.
  2. Traditional Korean Pottery: Consider using traditional Korean pottery for a more authentic and cultural experience. These cups, often handmade and intricately designed, can enhance the drinking experience with their aesthetic appeal.
  3. Cocktail Glasses: If you’re serving soju cocktails, use appropriate cocktail glasses. Highball glasses, martini glasses, and other types of cocktail ware can present soju-based drinks elegantly.

Modern Serving Suggestions

While traditional serving methods are essential, modern settings may call for some variations to cater to diverse customer preferences. Here are some contemporary serving suggestions:

  1. Soju Cocktails: To attract a wider audience, create a menu of soju-based cocktails. Popular options include the Soju Mojito, Soju Martini, and fruit-infused soju drinks. These cocktails can be an excellent way to introduce soju to customers who may not prefer straight spirits.
  2. Soju Flights: Offer soju flights featuring different brands and flavors. This allows customers to sample a variety of soju and discover their preferences. A soju flight can be an engaging and educational experience, perfect for soju newcomers.
  3. Food Pairings: Highlight food pairings on your menu. Soju pairs well with many dishes, particularly Korean cuisine, like kimchi, barbecue, and seafood. Pairing suggestions can enhance the dining experience and encourage customers to order food and soju.

Where to Source Soju for Your Business

Sourcing soju for your restaurant, bar, or retail business involves more than finding a supplier. It requires understanding the various avenues through which you can procure high-quality soju, ensuring reliable supply chains, and exploring exclusive deals to enhance your offerings. 

Local Distributors and Wholesalers

One of the most straightforward ways to source soju is through local distributors and wholesalers. These businesses specialize in supplying alcoholic beverages to restaurants, bars, and retailers, offering several advantages:

  1. Variety and Selection: Distributors often carry a wide range of soju brands, including popular ones like Jinro, Chamisul, and Charm, as well as lesser-known artisanal varieties. This allows you to offer your customers a diverse selection.
  2. Reliability: Established distributors have reliable supply chains and can provide consistent deliveries. Building a good relationship with a distributor can ensure a steady supply of soju, even during peak demand periods.
  3. Pricing: Buying in bulk from wholesalers can help you secure better pricing, improving your profit margins. Distributors may also offer promotions or discounts for regular customers.

Importers and Specialty Suppliers

Consider working with importers and specialty suppliers for premium and niche soju varieties. These companies focus on bringing unique and high-quality products from Korea to the international market.

  1. Exclusive Products: Importers can provide access to exclusive or hard-to-find soju brands that are not typically available through local distributors. This can set your business apart by offering something unique to your customers.
  2. Quality Assurance: Specialty suppliers often have stringent quality control measures to ensure the authenticity and quality of the soju they import. This is particularly important for premium soju offerings.
  3. Cultural Expertise: Importers who deeply understand Korean culture and market trends can offer insights and recommendations on which products might resonate best with your customer base.

Direct from Manufacturers

Establishing direct relationships with soju manufacturers can be beneficial if you aim to feature a specific brand prominently in your establishment. This approach can offer several benefits:

  1. Brand Partnerships: A direct partnership with a manufacturer can lead to marketing support, co-branded events, and exclusive promotions to attract more customers.
  2. Customization: Some manufacturers may offer customized labeling or special editions for your business, adding a unique touch to your offerings.
  3. Cost Efficiency: Direct sourcing can sometimes reduce costs by eliminating the intermediary, though this depends on your order volume and the manufacturer's policies.

Online Marketplaces

Online marketplaces are becoming increasingly popular for sourcing soju, especially for small businesses or those looking to try out different brands without committing to large orders.

  1. Convenience: Online platforms offer the convenience of browsing and ordering from a wide range of soju brands with just a few clicks. This can be particularly useful for small businesses or new ventures.
  2. Variety: Many online marketplaces stock a diverse selection of soju, including both mainstream and niche brands. This variety allows you to experiment with different products to see what resonates with your customers.
  3. Competitive Pricing: Online marketplaces often have competitive pricing and frequent promotions, which can be advantageous for cost savings.

Trade Shows and Industry Events

Attending trade shows and industry events focused on alcoholic beverages can provide excellent opportunities for sourcing soju. These events bring together manufacturers, distributors, and importers, allowing you to explore new products and establish valuable connections.

  1. Networking: Trade shows are an excellent platform for networking with industry professionals, learning about the latest trends, and finding potential suppliers.

Local Korean Communities and Markets

Engaging with local Korean communities and markets can be a great way to source authentic soju, especially if you’re looking for traditional or lesser-known brands.

  1. Community Connections: Building relationships with local Korean communities can provide insights into popular soju brands and trends. Community recommendations can guide you toward trusted suppliers.
  2. Cultural Events: Local Korean cultural events or festivals often feature stalls selling authentic Korean products, including soju. Participating in these events can help you discover new products and suppliers.
  3. Korean Markets: Korean grocery stores and markets often stock a range of soju brands. Establishing a relationship with these local vendors can ensure a steady supply of soju and possibly favorable terms.

Factors to Consider When Sourcing Soju

When deciding where to source soju for your business, consider the following factors to ensure you make the best choice:

  1. Quality and Authenticity: Ensure that the soju you source is of high quality and authentic. Working with reputable suppliers and checking for proper certifications can help guarantee this.
  2. Supply Consistency: Reliable supply is crucial, especially for popular items on your menu. Choose suppliers with a proven track record of consistency.
  3. Pricing and Margins: Consider your budget and desired profit margins. Compare prices from different suppliers to ensure you get the best deal without compromising quality.
  4. Customer Preferences: Understand your customer base and their preferences. This knowledge will help you choose the suitable types of soju to stock, whether traditional, flavored, or premium varieties.
  5. Regulatory Compliance: Ensure that all sourced soju comply with local regulations and licensing requirements for selling alcoholic beverages.

By exploring these various sourcing options and considering the critical factors mentioned, you can effectively stock a diverse and high-quality range of soju.
