Best Alkaline Water Brands: pH Levels, Taste and Mineral Comparison

Alkaline water is one of the most searched bottled water categories. Some shoppers look for the best alkaline water brands, while others want to know which bottled waters are naturally alkaline, which have the highest pH, and whether popular brands like Fiji or Evian are alkaline.

This guide explains what alkaline water means, what pH level is considered alkaline, how natural alkaline water differs from processed alkaline water, and how to compare alkaline bottled water brands.

Alkaline water is water with a pH above 7. A pH of 7 is considered neutral. Water below 7 is acidic, while water above 7 is alkaline.

Alkaline bottled water may get its pH from:

• Naturally occurring minerals
• Added minerals
• Electrolysis or ionization
• Filtration and remineralization

The key difference is whether the water is naturally alkaline at the source or made alkaline through processing.

A pH above 7 is alkaline. Many bottled alkaline water brands are marketed between pH 7.5 and pH 10.

pH Guide

Not all high-pH water tastes the same. Mineral balance, sodium content, and processing method all affect flavor.

There are two major types of alkaline bottled water.

Natural Alkaline Water

Natural alkaline water gets its pH from its source and naturally occurring minerals. Examples may include artesian, spring, or mineral waters that test above pH 7.

Artificial or Processed Alkaline Water

Processed alkaline water is usually purified and then adjusted through ionization, added minerals, or remineralization. These waters may have a very high pH but may not have the same natural mineral profile as spring or mineral waters.

Comparison

The best alkaline water depends on whether you want natural alkalinity, high pH, mineral content, or smooth taste.

Popular Alkaline Water Categories

Fiji Water is a common example of a mildly alkaline bottled water. Fiji lists its pH as 7.7.

Many alkaline water brands market pH levels from 8 to 10. However, highest pH does not always mean best. A very high pH may appeal to some shoppers, but taste, sodium level, mineral profile, and source transparency matter too.

When comparing high-pH waters, check:

• Is the pH naturally occurring or processed?
• Does the brand publish a water quality report?
• Are electrolytes naturally present or added?
• How much sodium is in the water?
• Does the taste match your preference?
• Is it suitable for your intended use?

Some bottled waters are mildly alkaline because of their natural mineral content. Others are intentionally processed to reach a higher pH.

Examples of Alkaline Water Types

Always check the bottle label because pH can vary by product line, region, and testing conditions.

Yes, Fiji Water is mildly alkaline. Fiji’s FAQ lists its pH as 7.7.

Fiji is a still artesian water with a smooth taste. Product label data commonly lists silica at 93 mg/L, calcium at 18 mg/L, magnesium at 15 mg/L, bicarbonates at 152 mg/L, TDS at 222 mg/L, and pH at 7.7.

Fiji is not a very high-mineral water compared with Gerolsteiner or San Pellegrino, but it is a popular choice for people who want still water with a naturally alkaline profile.

Evian is close to neutral to mildly alkaline depending on the source referenced. FineWaters lists Evian’s pH at 7.2, while Evian’s official mineral page focuses on mineral composition rather than promoting it as an alkaline water.

Evian is better described as a still natural mineral water from the French Alps rather than a dedicated alkaline water brand. It contains naturally occurring electrolytes and minerals, including calcium, magnesium, bicarbonates, and sodium.

For alkaline water with minerals, look for brands that publish mineral composition, not just pH.

Important minerals to compare:

• Calcium
• Magnesium
• Potassium
• Sodium
• Bicarbonate
• Silica
• TDS

Good Alkaline Water Buying Checklist

Sparkling mineral waters may have high mineral content but a lower pH because carbonation lowers pH. For example, Gerolsteiner is very mineral-rich but its sparkling version is often listed below pH 7.
