What do they put in water to make it taste better?

4 min read

According to the World Health Organization, minerals like calcium and magnesium are often added to purified water to enhance flavor and provide health benefits. For those seeking to replicate or improve on this, there are numerous ways to control what they put in water to make it taste better right at home.

Quick Summary

The taste of water is influenced by its mineral and additive content. Methods for improving flavor range from professional filtration systems that re-mineralize purified water to simple at-home infusions using fruits, herbs, or electrolytes. The optimal approach depends on the water source and personal taste preferences.

Key Points

  • Minerals Affect Taste: Natural minerals like calcium and magnesium are added to or are naturally present in water to give it a distinct and refreshing flavor.

  • Filtration Removes Contaminants: At-home and municipal filtration, especially with activated carbon filters, can effectively remove unpleasant tastes and odors caused by disinfectants like chlorine.

  • Natural Infusions Add Flavor: Adding fruits, vegetables, or herbs such as lemon, cucumber, or mint is a simple way to create flavorful, zero-calorie water at home.

  • Remineralization for Purer Water: Advanced filtration systems like Reverse Osmosis remove minerals, but remineralization filters or drops can be used to add beneficial minerals back in, improving the taste.

  • Chilling Improves Palatability: Serving water chilled can suppress unpleasant tastes and smells, making it more palatable without any additives.

  • Electrolytes for Taste and Health: Electrolyte drops or powders can enhance the flavor of purified water while also providing a boost of beneficial minerals.

  • Pipe Quality Matters: The quality and age of household plumbing can affect water taste. Old or corroded pipes can impart a metallic flavor to tap water.

The quest for great-tasting water often leads to a simple question: what do manufacturers and water enthusiasts add to plain H₂O to make it more appealing? The answer lies in a blend of science and preference, involving mineral composition, filtration, and natural infusions. While pure water is tasteless, the presence of certain minerals and the absence of contaminants create the flavor profile we find refreshing.

The Role of Minerals in Water Taste

Naturally sourced waters, like spring water, get their distinct taste from the minerals they collect while flowing underground. These minerals—including calcium, magnesium, and potassium—contribute to what is known as 'total dissolved solids' (TDS). The specific balance of these minerals dictates the water's taste profile, with calcium adding a smooth, milky note and magnesium contributing a slightly earthy flavor. Bottling companies often use this to their advantage, adding a specific blend of minerals back into purified water to achieve a consistent and palatable taste.

Conversely, water treatment plants often use chlorine to disinfect tap water, which can leave a distinct, unpleasant aftertaste. While safe, this chemical taste is a primary motivator for people to seek alternatives to improve their water's flavor. Removing these chemicals is the first step toward better-tasting water.

How Water Treatment Plants Enhance Flavor

Beyond disinfection, many municipal water treatment facilities take steps to improve the palatability of their water. Aeration, for example, is a process that exposes water to air, which allows volatile gases like chlorine to dissipate. Activated carbon adsorption is also used to remove organic compounds that can cause musty or earthy odors and flavors. The final step often involves adjusting the water's pH level, which can reduce the acidity that might otherwise cause a sour or metallic taste.

At-Home Methods to Make Water Taste Better

For those wanting to take control of their water's flavor at home, there are several effective methods available, ranging from simple additions to advanced filtration systems.

Natural Infusions

One of the simplest ways to add flavor is by infusing water with natural ingredients. This is a zero-calorie way to make water more exciting and increase hydration.

  • Citrus: Add slices of lemon, lime, or orange for a refreshing, tangy taste.
  • Berries: Fresh or frozen strawberries, blueberries, or raspberries add a subtle sweetness and can be frozen into ice cubes.
  • Herbs: Mint, basil, or ginger can give water a crisp, cooling, or spicy kick.
  • Cucumber: Sliced cucumber offers a clean, fresh flavor popular in spas and upscale restaurants.

Water Filtration Systems

For improving the base quality of tap water, filtration is the most effective method. Different systems target different issues and offer varying levels of purity and taste enhancement.

  • Pitcher Filters: Inexpensive and convenient, these use activated carbon to remove chlorine and other contaminants that cause bad tastes and odors.
  • Under-Sink Filters: These systems provide a more comprehensive filtration and connect directly to your plumbing, delivering filtered water from a dedicated faucet.
  • Reverse Osmosis (RO) Systems: An RO system is the most advanced at-home filtration. It forces water through a semi-permeable membrane, removing nearly all dissolved solids, including minerals. Because this leaves water tasting 'flat,' many modern RO systems include a remineralization cartridge to add beneficial minerals like calcium and magnesium back in for a balanced taste.

Electrolyte and Mineral Drops

For those who prefer purified or distilled water but miss the flavor and health benefits of minerals, electrolyte and mineral drops are a convenient solution. A few drops can transform flat-tasting water into a refreshing and mineral-rich beverage. This is also a popular method for athletes seeking to replenish lost electrolytes during exercise.

Conclusion: The Secret to Better-Tasting Water

The secret to better-tasting water is understanding that taste is directly tied to mineral content and the absence of unwanted contaminants like chlorine. Manufacturers of bottled water control this by adding a precise blend of minerals to purified water. However, you can achieve similar or even better results at home. By using a quality water filter to remove impurities, reintroducing beneficial minerals with drops or a dedicated filter, or simply infusing your water with natural ingredients, you can transform your tap water into a delicious and enjoyable beverage. The right method for you depends on your budget, source water quality, and desired level of control over the final taste.
