Sourcing and Purity: Ancient vs. Modern Origins
One of the most significant distinctions between these two popular unrefined salts lies in their origin. Redmond Real Salt is sourced from an ancient, protected seabed in Redmond, Utah, that is believed to be millions of years old. Covered by layers of volcanic ash, this salt deposit has been shielded from modern environmental pollutants and contaminants, including microplastics. This provides a unique selling point for those concerned about ocean pollution.
In contrast, Celtic salt, or sel gris, is harvested from modern ocean waters, traditionally from the coastal regions of Brittany, France. The salt is collected in clay-lined ponds where the seawater naturally evaporates, and it is hand-harvested using age-old techniques. Because it comes from the current ocean, it is more susceptible to modern-day environmental factors, though reputable brands take care to minimize these concerns. Its characteristic light gray color comes from the clay minerals it is harvested with.
Mineral Content and Composition
Both Redmond and Celtic salts are prized for their naturally occurring trace mineral content, which is retained due to minimal processing. While standard table salt is stripped of these minerals, both Redmond and Celtic versions offer a wider spectrum of elements beneficial for health. However, their specific mineral compositions differ slightly based on their source.
Redmond Real Salt contains over 60 trace minerals, including potassium, calcium, and magnesium, which give it a subtle, sweet flavor profile. The company provides a full elemental analysis, which details the specific percentages of its mineral content, including sodium chloride, calcium, and potassium.
Celtic salt also contains a rich blend of minerals, with some analyses showing higher levels of magnesium and moisture content, giving it a unique taste and texture. Its mineral content is dependent on the specific coastal region and harvesting conditions. Proponents often tout its high magnesium levels as beneficial for hydration and muscle function.
Culinary Applications and Flavor Profile
The subtle differences in mineral composition lead to distinct flavor profiles and uses in the kitchen. The choice often comes down to personal taste and the dish being prepared.
- Redmond Real Salt: Described as having a subtly sweet and smooth flavor, it's often preferred for general cooking and baking where a clean, enhanced salty taste is desired. Its fine grind is versatile for everyday use, while the kosher grain is excellent for seasoning meats.
- Celtic Salt: With a brinier, slightly earthy flavor, Celtic salt is often used as a finishing salt to add a pop of flavor and crunch. Its higher moisture content also gives it a unique texture that some chefs prefer. It is available in various grinds, from fine to coarse.
Comparison Table: Redmond Real Salt vs. Celtic Salt
| Feature | Redmond Real Salt | Celtic Salt |
|---|---|---|
| Origin | Ancient, protected seabed in Utah, USA. | Modern ocean water, traditionally from Brittany, France. |
| Purity Concerns | Minimal risk of modern ocean pollutants due to ancient, protected source. | Potentially exposed to modern ocean pollution, though from reputable sources risk is low. |
| Mineral Content | Over 60 trace minerals, including naturally occurring iodine. | Over 80 trace minerals, particularly noted for magnesium and higher moisture. |
| Sodium Content | Approximately 93% sodium chloride, based on analysis. | Approximately 84% sodium chloride, due to higher moisture and mineral content. |
| Flavor Profile | Subtle, sweet, and smooth. | Briny, earthy, and more complex. |
| Best For | Everyday cooking, baking, seasoning. | Finishing salt, adding texture and a brine-like flavor. |
| Appearance | Pink or red hue from mineral content. | Light gray color from clay harvesting pools. |
Health Claims and Considerations
Both Redmond and Celtic salts are marketed as healthier alternatives to refined table salt due to their mineral content and lack of processing. Some health claims associated with unrefined salts include better hydration, electrolyte balance, and improved digestion. However, it is important to remember that the amount of trace minerals in a typical serving of salt is very small and should not be relied upon as a primary source of these nutrients.
For example, while Celtic salt is often lauded for its magnesium content, a quarter teaspoon contains only a tiny amount of this mineral. The health benefits are more directly tied to replacing refined salt (which lacks these minerals and often contains anti-caking agents) with an unrefined alternative.
Another point of consideration is iodine. Standard table salt is often iodized to prevent iodine deficiency, a public health measure implemented in many countries. While Redmond Real Salt claims to have naturally occurring iodine, the amount can vary. Celtic salt is not a reliable source of added iodine. If you switch to an unrefined salt, you may need to ensure adequate iodine intake from other dietary sources like seafood, dairy, or iodized supplements.
Making Your Choice: Which Salt is Right for You?
The decision of whether Redmond Real Salt or Celtic salt is better largely depends on your priorities. If purity from modern pollutants is your main concern, Redmond's ancient, protected source is a strong contender. If you prefer a briny, flavorful finishing salt with a higher moisture content, Celtic salt may be your ideal choice. For those who use kosher salt in their meat preparation, Redmond's kosher-grain option is specifically recommended for its ability to pull out proteins and create a perfect caramelization. Ultimately, both are excellent unrefined alternatives to processed table salt, and many home cooks enjoy using both for different culinary purposes.

Conclusion: Flavor, Purity, and Personal Preference
In the debate over whether Redmond Real Salt or Celtic salt is superior, there is no single right answer. Both are minimally processed, mineral-rich alternatives to standard table salt, each with its own merits. Redmond's appeal lies in its ancient, protected source and smooth flavor, while Celtic salt is celebrated for its briny complexity and traditional harvesting methods. Rather than choosing one over the other, many culinary enthusiasts incorporate both into their kitchen to take advantage of their distinct qualities. The best salt for you is the one that best suits your personal health priorities and culinary tastes.
A Final Word on Salt and Health
Regardless of which unrefined salt you choose, remember to consume it in moderation. The American Heart Association continues to advise monitoring overall sodium intake to support cardiovascular health. While unrefined salts offer trace minerals, they still consist primarily of sodium chloride, and excessive consumption can lead to health issues. A balanced diet rich in whole foods remains the most reliable way to obtain essential vitamins and minerals.
