The Surprising Low Sodium Content of Most Beers
Contrary to some popular beliefs, most mainstream beer styles, such as lagers and ales, are very low in sodium. A standard 12-ounce can or bottle often contains only 10 to 20 milligrams of sodium. For context, the recommended daily allowance for sodium is less than 2,300 milligrams for most adults, and even lower for those with certain health conditions. This means a single beer contributes less than one percent of your daily sodium intake.
Where Does the Sodium Come From?
Sodium isn't a primary ingredient brewers add to most beers. The small amounts present are derived from two main sources:
- Brewing Water: The natural mineral composition of the water used in brewing is the most significant source. Different geographical regions have water with varying mineral profiles, which historically influenced the types of beers brewed there. A brewer may adjust their water profile, which includes sodium content, to achieve a desired flavor or to mimic water from famous brewing cities like Dublin or Burton-on-Trent.
- Malt and Other Ingredients: While less significant, trace amounts of sodium also come from the malt and other ingredients used in the recipe. These natural sources contribute minimally to the final sodium count.
The Exception to the Rule: Gose and Specialty Beers
While most beer styles are low in sodium, there are exceptions. The most prominent example is the Gose (pronounced goes-uh), a traditional German wheat beer.
Characteristics of Gose:
- Intentional Salt Addition: Gose is brewed with added salt and coriander, giving it a distinctive tart and salty flavor profile.
- Historical Roots: The saltiness in original Gose came from the naturally saline water of the Goslar river in Germany, though modern brewers add salt intentionally.
- Craft Innovation: The craft beer movement has seen a resurgence of Gose, with many brewers experimenting with fruit additions and other variations, like watermelon or mango, which balance the salt and tartness.
Beyond Gose, some brewers use salt to add complexity to other styles. Salt can enhance sweetness in stouts or reduce the perception of bitterness in certain ales. For instance, a salted caramel stout would use sea salt to create a richer, more balanced flavor.
Comparison Table: Sodium in Different Beverages
To put the sodium content of beer into perspective, consider this comparison table. The values for beer represent typical averages, while specialized or craft versions may vary significantly.
| Beverage (approx. 12 oz) | Average Sodium (mg) | Notes |
|---|---|---|
| Regular Beer | 10–20 | Standard lagers and ales |
| Light Beer | 5–15 | Slightly less due to lighter composition |
| Gose Beer | 150+ | Depends on the brewer, intentionally salty |
| Cola | 30–40 | Higher than typical beer |
| Sports Drink | 250–500 | Specifically formulated to replace electrolytes |
| Apple Juice | ~10 | Generally low in sodium |
Health Considerations for Beer and Sodium
For the average person, the sodium content of beer is not a significant health concern. However, there are two key areas where it becomes relevant:
Low-Sodium Diets
Individuals on a low-sodium diet for conditions like high blood pressure or heart disease should be mindful of all sources of sodium. Standard beers are generally acceptable in moderation, but specialty styles like Gose or heavily salted varieties should be consumed with caution. Always check the nutritional information for specific craft beers, as sodium content can vary widely.
Beer Potomania: A Rare But Serious Condition
While not caused by high salt levels, it's crucial to understand a rare condition called beer potomania, or beer-induced hyponatremia. This occurs when an individual consumes a very large volume of beer while maintaining a poor diet, particularly one low in protein and other solutes. Because beer has very few solutes, this excessive fluid intake dilutes the body's sodium levels to dangerously low levels, a condition called hyponatremia. This can cause neurological symptoms and is a serious medical emergency. It is an extreme case and not a risk for casual or moderate drinkers.
Conclusion
In conclusion, the claim that there is much salt in beer is largely a myth for most standard varieties. The vast majority of beers are a minimal source of dietary sodium, with the trace amounts coming from the natural minerals in brewing water and malt. The exception to this rule is the Gose style and certain modern craft beers where salt is an intentional, character-defining ingredient. For most drinkers, the sodium in beer is not a concern, but those on low-sodium diets or who drink excessively should be aware of the different levels and potential risks.

Frequently Asked Questions
Is a lager high in salt?
No, lagers are typically very low in sodium, with most mainstream varieties containing well under 20 milligrams per serving.
Why do some people add salt to their beer?
Historically, some added salt to improve the taste of lower-quality beer or to settle the head. In modern times, adding beer salt is a tradition in some areas, believed to cut bitterness and enhance flavor.
What is beer potomania?
Beer potomania is a rare and dangerous condition of low blood sodium (hyponatremia) caused by excessive beer consumption combined with a poor diet. It is not caused by high salt in the beer itself, but rather the low solute content.
Can I drink beer on a low-sodium diet?
Yes, most standard and light beers are fine for those on a low-sodium diet due to their minimal sodium content. However, specific styles like Gose and excessively salted craft beers should be avoided or consumed very rarely.
Does light beer have less sodium than regular beer?
Light beer can have slightly less sodium than a regular beer, but both are generally considered very low in sodium compared to other beverages and overall dietary intake.
Does the sodium in beer affect the taste?
Yes, sodium can influence flavor. At low to moderate levels, it can enhance malt sweetness and improve mouthfeel, while at higher concentrations (like in a Gose), it will contribute a noticeable salty taste.
Are there any beer brands that are specifically low in sodium?
Most mainstream and craft beers are already low in sodium. If you are extremely sensitive to sodium, checking the nutrition label is always the best option. Light lagers like Bud Light or Michelob Ultra are consistently very low.
Keypoints
- Typically Low in Sodium: Most standard and light beers contain very little sodium, often less than 20 mg per 12-ounce serving.
- Brewing Water is the Primary Source: The trace amounts of sodium in most beers come from the natural mineral content of the brewing water and ingredients like malt.
- Gose is a Salty Exception: The German Gose beer style is intentionally brewed with added salt and coriander, making it a distinctly salty and tart beer.
- Not a Major Dietary Concern: For most people, the low sodium levels in beer are not a significant contributor to their daily intake, unlike processed or restaurant foods.
- Excessive Drinking Poses a Rare Risk: Extremely heavy beer consumption paired with a poor diet can lead to a serious medical condition called beer potomania (hyponatremia) due to fluid dilution, not high salt levels.
