Have you ever taken a sip of water and thought, “That tastes weird”? Maybe one brand tastes crisp and refreshing while another may have a slightly metallic or mineral-like flavor. Maybe your tap water tastes different from the water at a restaurant, or the water from your refrigerator tastes different than bottled water from the store. Water may seem like it should taste like, well, nothing. But the truth is that water can have a surprisingly distinct taste, and there are several reasons why. Everything from minerals and dissolved compounds to treatment methods, temperature, and even the source can influence the taste. Understanding those differences can help you make more informed choices about the water you drink.
What Gives Water Its Taste?
Pure water itself is essentially tasteless. What we perceive as the “taste” of water generally comes from substances dissolved in it. Natural water picks up minerals and other compounds as it moves through the environment. Groundwater, for example, can come into contact with rock and soil, potentially absorbing minerals along the way. Municipal drinking water is also treated to meet safety standards, and those treatment processes can influence its final taste.
Some of the biggest factors that affect water’s flavor include:
- Mineral content
- Chlorine and other treatment compounds
- Dissolved solids
- Source of the water
- Purification method
- Temperature
- Packaging and storage
That’s why two bottles of water can taste noticeably different even though both are simply labeled “drinking water.”
Minerals Can Change the Flavor of Water
One of the biggest contributors to water’s taste is its mineral content. Calcium, magnesium, sodium, and other naturally occurring minerals can make their way into water as it travels through rock and soil. In certain concentrations, these minerals can give water a distinct taste.
Some people describe mineral-rich water as earthy, chalky, or slightly salty, while others enjoy that particular flavor. The important thing to understand is that “mineral” and “pure” aren’t necessarily interchangeable terms. Different types of bottled water are produced and treated differently, and the contents can vary significantly from one product to another. This is one reason it’s worth paying attention to what a water label actually says rather than assuming all bottled water is the same.
Why Does Tap Water Sometimes Taste Like Chlorine?
If you’ve ever filled a glass from the tap and noticed a swimming-pool-like smell or flavor, you’re not imagining it. Municipal water systems commonly use disinfectants such as chlorine to help control microorganisms in drinking water. While these treatments play an important role in water treatment, they can also affect the way water smells and tastes. The amount of chlorine that reaches your glass can vary depending on the water system, treatment process, and other factors. This is also one reason some people prefer filtered or purified water for drinking. Different purification methods can reduce or remove various substances that contribute to taste.
Your Water Source Matters, Too
The journey water takes before it reaches your glass can influence its final composition. Natural water moves through a complex cycle of evaporation, condensation, and precipitation. As it travels through the environment, it can pick up minerals and other substances from the ground and surrounding materials. It’s an interesting reminder that bottled water isn’t one single category. The source, treatment process, and final composition can all vary.
Filtration, Reverse Osmosis and Distillation Aren’t the Same
When people say they drink “filtered water,” that doesn’t necessarily tell you exactly what has happened to the water. There are numerous approaches to water treatment, and each works differently.
- Filtration generally involves passing water through a material designed to capture or reduce certain particles or substances.
- Reverse osmosis (RO) uses pressure to push water through a semipermeable membrane. Depending on the system and operating conditions, RO can reduce many dissolved substances and contaminants.
- Distillation takes a different approach. Water is heated until it becomes vapor, leaving many substances behind. The vapor is then condensed back into liquid water.
At Le Bleu East Tennessee, we take purification seriously. Our five-step purification process centers on fractional vapor compression distillation, a process that turns water into vapor and then condenses it back into purified water, leaving many impurities behind. We then use ozonation as an additional step to sanitize the water. The result is Le Bleu Ultra Pure Water–purified five steps beyond Mother Nature. These distinctions matter because the treatment process can have a direct impact on what’s left in the finished water, and ultimately, its taste.
Why Does Le Bleu East Tennessee’s Water Taste Different?
Le Bleu East Tennessee’s approach is centered around producing “ultra pure” water: water composed of hydrogen and oxygen without the minerals and other substances commonly found in natural water. Our purification process uses distillation to turn water into vapor and then condense it back into liquid. Le Bleu explains that this process leaves behind many impurities, including inorganic minerals, heavy metals, chlorine, and other substances.
Le Bleu East Tennessee also uses ozonation as another step in its purification process. Ozone is generated using high-voltage electricity and is used as a disinfectant and sanitizer during water treatment. The result is water with a very different composition from water that retains naturally occurring minerals. And that difference can be noticeable. For some people, the appeal of ultra-pure water is its clean, light, and refreshing taste. Without the mineral profile found in many natural waters, fewer dissolved substances are contributing their own flavors.
So, What Makes Water Taste “Good”?
There’s no universal answer, as preferences vary from person to person. Some people prefer water with a noticeable mineral character. Others prefer water that tastes as neutral and clean as possible. The important thing is understanding why those differences exist.
When you know what you’re tasting and why you’re tasting it, you can look beyond the front of the bottle and make a more informed choice. For Le Bleu East Tennessee, that choice comes down to purification. Our five-step process is designed to remove substances that can affect the water’s purity and flavor, resulting in what the company describes as ultra-pure water with a light, refreshing taste. So the next time someone says, “This water tastes different,” they’re absolutely right. Water may look simple, but what’s inside, and how it got there, can make a surprisingly big difference.
