What Minerals Do They Put in Dasani Water for Its Signature Taste?

After Dasani's initial source water is purified using reverse osmosis, trace amounts of minerals are added back into the product for flavor. This process is the answer to the question of what minerals do they put in Dasani water, and it is a key step in creating the brand's consistent, signature taste.

Quick Summary

Dasani water is purified via reverse osmosis, and trace minerals are added to enhance its taste. The specific minerals include magnesium sulfate, potassium chloride, and sodium chloride.

Key Points

• Purified Tap Water: Dasani begins as municipal tap water that is then purified through reverse osmosis.

• Added Minerals: The specific minerals added for taste are magnesium sulfate, potassium chloride, and a trace of sodium chloride.

• Taste Consistency: Minerals are re-added after purification to give the water a consistent, crisp flavor.

• FDA Regulation: The added minerals are present in trace, safe amounts regulated by the FDA.

• Sodium-Free: As of July 2025, Dasani began transitioning to a zero-sodium formula.

• Reverse Osmosis: This purification process removes most impurities and minerals, making the re-mineralization step necessary for flavor.

The Dasani Purification and Re-Mineralization Process

Dasani water originates from local municipal water supplies and undergoes a stringent multi-stage purification process to remove impurities. This ensures a consistent base product before the addition of minerals.

Added Minerals for a Consistent Taste Profile

To achieve its consistent taste profile across bottling plants, Dasani adds specific minerals after purification. Without these additives, purified water would lack a distinct flavor. The added minerals are primarily magnesium sulfate, potassium chloride, and a small amount of sodium chloride.

• Magnesium Sulfate: Also known as Epsom salt, it contributes to the taste and potentially mouthfeel.
• Potassium Chloride: A salt substitute used to enhance flavor. It is considered safe in the small quantities used.
• Sodium Chloride (Salt): Added in a dietarily insignificant amount to round out the flavor without making it taste salty.

Dasani vs. Other Water Types

Dasani's production method creates a product distinct from other types of water.

Addressing Common Criticisms

Dasani has faced criticism, including its withdrawal from the UK market in 2004 following the revelation it was purified tap water and a contamination recall. Concerns about the added minerals have also been raised. However, the quantities used are regulated by the FDA and are considered safe for consumption. The company maintains that the sodium content is dietarily insignificant.

Conclusion

In summary, what minerals they put in Dasani water are trace amounts of magnesium sulfate, potassium chloride, and sodium chloride. These are added after extensive purification of municipal water, including reverse osmosis, to ensure a consistent and controlled flavor. This differs from natural spring water, which relies on naturally occurring minerals for taste. The added minerals are for taste enhancement and are present in safe, insignificant amounts, despite some past controversies and online misinformation. The purification and re-mineralization process is central to creating Dasani's specific brand taste.

Frequently Asked Questions

Why does Dasani add minerals to its water?

Dasani adds trace amounts of minerals, including magnesium sulfate and potassium chloride, to its purified water to enhance the flavor and ensure a consistent, crisp taste profile.

Is Dasani water just bottled tap water?

Yes, Dasani water starts as municipal tap water. However, it undergoes a multi-stage purification process, including reverse osmosis, before minerals are added back in.

What are the specific minerals found in Dasani?

The primary minerals added to Dasani for flavor are magnesium sulfate, potassium chloride, and a trace amount of sodium chloride (salt).

Is the salt in Dasani a health concern?

No, the amount of sodium chloride added to Dasani is dietarily insignificant. According to Coca-Cola, the amount is so small it is declared as 0mg per serving on the nutrition label based on FDA rules.

Are the minerals in Dasani safe to drink?

Yes, the minerals are added in very small, regulated amounts and are not considered a health concern for standard consumption. Bottled water is regulated by the FDA.

What is the purpose of reverse osmosis in Dasani's production?

Reverse osmosis is a purification process that removes most dissolved solids and impurities from the source water. This provides a clean, pure base before the specific minerals are added for taste.

How does Dasani's mineral content compare to spring water?

Unlike natural spring water, which contains minerals from its underground source, Dasani's mineral content is artificially added after purification to create a consistent, manufactured taste profile.
