October 28, 2025 •

3 min read

According to official marketing, Han Spirits explicitly confirms its products, including Han Soju, are gluten-free, providing reassurance for consumers with dietary restrictions. However, understanding the broader context of soju production is important for anyone managing a gluten-free lifestyle.

Quick Summary

Han Soju is marketed as gluten-free, primarily using rice for distillation. The distillation process generally removes gluten, but ingredient variations in other soju brands and additives can introduce risks for highly sensitive individuals.

Key Points

Explicitly Labeled: Han Soju is marketed as gluten-free by the manufacturer, Han Spirits, making it a safe choice for most.
Distillation Process: The process of distilling soju removes gluten proteins, rendering the final spirit gluten-free, even if fermented from gluten-containing grains.
Rice-Based: Han Premium Soju is made from high-quality, polished rice, a naturally gluten-free grain.
Additives in Flavored Soju: Flavored soju varieties may contain gluten-based additives, so stick to unflavored Han Soju or verify the specific product's ingredients.
Cross-Contact Concern: Individuals with Celiac disease or severe sensitivities should be aware of potential cross-contact risk, although it is minimal in distilled spirits.
Check the Label: Always look for explicit 'gluten-free' labeling on the bottle, even with generally safe spirits.

Is Han Soju Safe for a Gluten-Free Diet?

Yes, according to its producers, Han Soju is considered safe for those on a gluten-free diet. The company markets its products as gluten-free, which is a strong indicator of its safety profile for most consumers. Han Premium Soju, for example, is a grain-based distilled spirit made with high-quality, polished rice during its fermentation and distillation process. For many soju brands, the raw ingredients can vary widely, but for Han Soju, its marketing directly addresses and confirms its gluten-free status.

The Science of Distillation and Gluten

The reason most spirits, including soju, are considered safe even if they originate from gluten-containing grains is the distillation process itself. Distillation involves heating a fermented liquid and collecting the resulting alcoholic vapor. This process effectively separates the alcohol from the heavier, non-volatile components of the mash, which includes the gluten proteins. The gluten proteins are left behind in the distillation pot, and the final distilled spirit contains no gluten. For this reason, reputable health organizations like Beyond Celiac confirm that distilled alcohol is generally gluten-free, regardless of the starting grain.

Potential Risks and How They Apply to Soju

While distillation is highly effective, risks can still exist, particularly for individuals with Celiac disease or severe gluten sensitivities. The potential for risk comes from two main sources: additives and cross-contact.

Additives: This is a major concern, especially with flavored varieties of soju. After distillation, manufacturers might add flavorings or sweeteners, which could potentially contain gluten. Popular flavored sojus, such as those with peach or grape, could include additives that are not pure and gluten-free. It is crucial to check the specific brand's ingredients for confirmation.
Cross-Contact: This is a risk for extremely sensitive individuals. If a spirit is processed in a facility or on equipment that also handles gluten-containing products, there is a theoretical, albeit small, risk of cross-contamination. While the distillation process mitigates this risk significantly, it's a valid concern for the most sensitive.

Comparison: Soju vs. Other Gluten-Free Spirits

This table outlines the gluten-free status of common spirits, comparing them to soju.


Spirit	Traditional Base Ingredient	Distilled?	Generally Gluten-Free?	Notes
Han Soju	Rice (Polished)	Yes	Yes (explicitly marketed)	Safe choice; explicitly labeled gluten-free.
Traditional Soju	Rice, wheat, barley, sweet potato	Yes	Yes (but check additives)	Most unflavored versions are safe, but check for barley or additives.
Vodka (Potato)	Potato	Yes	Yes	A naturally gluten-free option.
Vodka (Grain)	Wheat, corn, rye	Yes	Yes (due to distillation)	Distillation removes gluten, but check for celiac sensitivity concerns.
Tequila	Blue agave	Yes	Yes	Naturally gluten-free.
Rum	Sugarcane	Yes	Yes	Naturally gluten-free.
Whiskey	Barley, corn, rye	Yes	Yes (but check for celiac concerns)	Distilled, but some celiacs avoid due to starting grain.

How to Verify Gluten-Free Status

For those who are highly cautious, here are some steps to verify a soju's gluten-free status:

Look for Labeling: Check the product's bottle for official 'gluten-free' certification or explicit statements. Han Soju provides this, which is a significant plus.
Contact the Manufacturer: If in doubt, reach out directly to the company. Han Spirits provides information on their website, often through trade resources.
Stick to Unflavored Varieties: Original soju is less likely to contain gluten-based additives than flavored versions. If you choose a flavored soju, exercise more caution.
Consider Ingredients: While most soju uses rice, some brands may use wheat or barley. The distillation process should still render it safe, but this is a good point for extremely sensitive individuals to consider.

Conclusion: Is Han Soju Right for Your Diet?

Based on available information and explicit company claims, Han Soju is a reliable choice for a gluten-free lifestyle. The brand markets its products as gluten-free, using polished rice as a key ingredient, which aligns with standard gluten-free alcohol practices. While the distillation process makes most spirits safe, Han Soju's specific labeling provides an extra layer of assurance. Always be mindful of potential additives in flavored versions and consider individual sensitivity levels, especially for those with Celiac disease. For a broader perspective on gluten-free alcohol safety, resources like the Beyond Celiac website offer excellent guidelines.
