In today’s coffee cultured world, coffee lovers and baristas are in urge to bring out the best new flavors of coffee in the market. Best water for coffee is a new topic to look out for coffee lovers. Once you set other materials for making coffee then the major contribution of water is left. Once you set all ingredients then the resulting coffee would be the one you will never be going to taste again. So, yes the water quality is all worth it!

You have frequently heard that coffee beans, origin, roasting, and blender are prior things for making the best coffee but another main ingredient is the quality of water. Researchers suggest that the more purified water is the resulting coffee would be more delicious and pure. 

But anyhow, water has many forms available in nature. Such as hard water, soft water. Hard water contains minerals such as calcium and magnesium that bring out different flavors in many ways but also extract the flavor from ground coffee beans.

Since coffee is a mixture of 98% water quantity so the quality of water is an important factor to consider for the best results. Without filtration, water contains minerals that bring out the best flavor of the coffee. Such as salt brings flavor to your food, just like water minerals are also crucial for coffee. Perfect brewing, roasting, and nice quality water bring out the delicious coffee you have never tasted before.

In the meantime, let us have a look at different types of water and how their quality affects the coffee flavor.

Types of Best Water:

In nature, water is available in different forms such as unfiltered tap water, osmotic spring water, aqua water, and rainwater. Water makes up 98.5% of the volume of brewed coffee and around 90% of espresso, therefore it has a serious influence.  But manmade techniques for purifying water and developing it into other forms are now at their peak.

  • Tap water.
  • Filtered water.
  • Purified water.
  • Distilled water.
  • Bottled Water.
  • Carbon filtered water.

There are different forms of water that are derived by humans from natural water. Let’s have a look at each of them.

Tap Water for Coffee:

Tap water is the most accessible water and contains more minerals as compared to other converting forms. Reason behind? The reason behind the quality of water such as its hardness, softness, pH, and minerals quality depends on the area of your residence. If you are living near the sea, mountains, and underground these areas will naturally affect the alkaline water texture and then changes the flavor of your coffee.

Different natural minerals such as calcium, magnesium, phosphorus, and aluminum with other acidic substances affect the water quality. Some people think that their tap water is safe to drink, but still, it contains disinfecting particles and some impurities. The unpleasant odor and taste come from chemicals used in the disinfection process.

If the tap water is not purified, it will automatically affect your coffee taste. That’s how the areas affect your water quality. On the other hand, soft water compels strong coffee. But hard water eventually contains all these minerals to give you 10 times more delicious coffee than soft water.

  • Calcium and Magnesium:

Calcium and magnesium both are important for extracting coffee flavor and taste. This mineral is abundantly available in the UK water sea which will cause limescale issues. A high concentration of magnesium ions extends the flavor of coffee in water and enhances the taste. While it is also a reason for causing acerbic texture. Both calcium and magnesium with bitter and sweet tastes are essential for extracting coffee taste.

  • Potassium and Sodium:

The concentration of sodium in tap water is usually high than potassium. A low level of these minerals develops a sweet flavor to the coffee. Sodium is the main component of salt so a high quantity of tap water will eventually make your coffee deleterious. Salty coffee…Looks different!

The recommended sodium concentration in coffee brewing would be just 10mg/L. Because it is available in tap water at a 200mg/L level which is harmful for coffee extraction.

  • Bicarbonates Ion:

High levels of carbonates, bicarbonates, and hydroxides combine with other metabolites and reduce the alkalinity and pH of your tap water. It was observed that high levels of these ions are bad for water quality.

  • The pH for best water for coffee:

The measurement of the acidic and alkaline nature of water is known as ph. The lower pH means water is more acidic while the higher pH means it is basic/alkaline in nature. For hard water, the water pH is acidic because it is strong in minerals.  

The ph. scale contains units from 1 to 7 and onwards. 1 to 7 are neutral/acidic while above them are alkaline water ratios. The normally recommended pH for coffee would be between 6.5 to 7.5 which is considered good for the best coffee flavor.

For coffee alkaline nature of water is best because it balances the flavor and bitter taste as well. But the high level of alkaline would make you to left the cup of coffee. Acidic water is only good for developing flavor.

Never prepare your coffee with unpleasant bad water. Your coffee water should be clean, neat, and purified from other dust particles. Sodium concentration should be less than 10mg/L while chlorine level should be 0mg/L in your water for espresso coffee.

  • Chlorides:

Sodium chloride ions have their own deleterious effects on stainless steel objects. A high level of chloride will eventually weaken the coating layers of that material and causes corrosion. While a small number of chlorides may develop a sweet texture in your coffee but for that purpose, you need to testify your coffee machine first.

  • Sulphates:

Several sulphides such as sulphates, sulfur do not show a good impact on the water. In fact, they emphasize bitterness in coffee. When sulphides combine with the calcium they make calcium sulphate that causes erosion and hard white wax inside your stainless steel coffee makers.

Bottled Water for Coffee:

For further discussion about the best water to use for coffee, we are landed here to review the best brand of water for coffee. Researchers find out that bottled water contains both low and high quantities of minerals so you can’t say that these water brands are best for making your coffee delicious.

The hardness of minerals finds out in most municipal water supplies because of the high concentration of minerals such as alkalines, pH, and carbonates. Bottled water also contains a carbon concentration that makes your water footprint heavy. Although these water brands are reaching the peak of their earnings in the market because of high price tags. They are creating a big source of environmental pollution. Your greenery areas are polluted because of the plastic bottles.

If you want to use bottled water, try to use it by checking its mineral levels. If its minerals levels fall between 50 to 5157mg/L it would be best for brewing coffee. Some brands mentioned in the bottle description that they have not added calcium ions but magnesium is present then go for it. Because magnesium enhances the flavor of your coffee while calcium makes your cup of coffee bitter. But it’s better to not use bottled water because it is a package of microplastic particles and disturbs your environment.

Distilled water for coffee:

Find out the best water for coffee would be a big task for coffee lovers. But after reading this detailed review you will find out your hunting. Distilled water also called soft water that contains low contamination because it is passed by several purification and filtration processes. This water pulled off its calcium and magnesium concentration so it is the best choice of water if you are using it for making coffee.

Due to the lack of minerals calcium and magnesium the resulting water would be bitter if you use it in coffee. That’s why distilled and pure water is a bad source for making sweet coffee. But if you are a fan or addicted person to bitter coffee then must go for purified water.  Just like distilled water, boiled water after water boiler boiling will lose its minerals concentration, and the resulting water would be a pure form of water.

Water filtration Processes:

Water goes through several filter processing to remove its minerals and other sediments that are dissolved in it. Contaminates such as nitrates, heavy metals, and pesticides are removed in this process. The following steps are included in the water filtration process.

What is TDS?

The measurement of water contents for making coffee is known as ‘’ Total Dissolved Solid’’ or TDS. This term evaluates all the less and major contents of water such as particulate matter, minerals, and ions. In fact, researchers said that it describes the relationship between hardness, softness, and buffer of water. So for measuring the water contents and its alkalinity TDS meter is used for that purpose.


To conclude this topic about the best water for coffee you are now well aware of choosing the best coffee water. Different types of water are available in nature but man-made activities convert it into further useful forms such as distilled water, soft water, and filtered water. Some people like hard water that contains all its minerals content to mix up with coffee and give vibrant flavor.

Whereas some people like soft water which is a distilled, pure form of water that extracts its all minerals. Research recommends that never go for reverse osmotic and pure distilled water because they make your brewed coffee flavorless. Once the water temperature and pH level fall beyond the limit it will also be a reason behind flavorless, tasteless coffee.


  • What type of water makes the best coffee?

    Two essential elements, calcium, and magnesium are eliminated from this type of water. If you're going to use a coffee maker, it's best to use distilled water. The mineral build-up is reduced, and scaling is avoided, which could damage your appliance.

  • Is it okay to make coffee with tap water?

    You read that right – tap water. When it comes to preparing coffee, tap water is often the best option. You can use it as long as it is clean, fragrant, and tastes well. The above-mentioned easy filtration process can make it ideal for making a great cup of coffee.

  • What pH should water be for coffee?

    The Gourmet Coffee Association of America advises that your water be completely neutral, but a pH of 6.5 to 7.5 is OK.

  • Does water makes a difference in coffee?

    Hard water is inferior when it comes to making coffee because its high mineral content mutes the flavor of the coffee. Because of the lower mineral concentrations in tap water, it makes superior coffee.
