Should you use filtered water to make coffee?

In this text we will answer the question: “Should you use filtered water to make coffee?”. In addition, we will elucidate how important is filtered water when making coffee and discuss how to filter the water before use to prepare coffee.

Should you use filtered water to make coffee?

Yes, unfiltered water has a lot of chlorine and can contain impurities; this greatly modifies the flavor of the coffee to be consumed. The ideal is to use filtered or mineral water, as this way you can guarantee purity and cleanliness of the liquid. More than that, you are assured that you will be enjoying your drink to its full potential.

The most common mistake in preparing a coffee is precisely the lack of criteria in the use of water. Tap water, for example, may be the most practical solution, but not the right one. If it has impurities or excess chlorine, the quality of the drink is compromised.

How important is filtered water when making coffee?

Have you ever noticed how tap water has a stronger flavor than filtered mineral water, which is usually bland? That’s because all the way to your glass, the water comes into direct contact with the plumbing and dirt present in these places.

It may even be colorless and odorless, but it is possible to feel the change in flavor due to the small impurities and microorganisms present in the drink. These impurities are so small that we often can’t see them with the naked eye, but that doesn’t mean they can’t compromise our health or change the taste of coffee.

To solve this problem is very simple, just filter the water or you can also use bottled mineral water directly. Never boil the water before preparing the coffee, because in addition to being ineffective, the high temperature of the water can damage the internal components of your coffee maker.

Most espresso machines are designed to deliver the best coffee quickly and efficiently and, for this reason, have a technology that automatically identifies the ideal water temperature for brewing your coffee. All you need to do is make sure the reservoir is clean and has filtered water.

But if you choose to prepare the coffee using another method, such as the French press or brewed coffee, avoid boiling the water as well. That’s because high temperature water can burn the coffee grounds, making your drink more bitter.

How to filter the water used to prepare coffee?

If you are not in the habit of using bottled natural mineral water, then you probably have an electric or even clay water filter in your home, right? That’s enough! Some faucet models even have a water filter option. If that’s the case for you, there’s no reason to worry either!

But if you don’t have a filter nearby, a good option is to use a water filter installed inside your espresso or coffee machine water tank. The filter is considered an accessory and does not come with the machines directly from the factory, but can be purchased in our virtual store.

You also need to be very careful when choosing your water filter. After all, original products do not affect the functioning of your machine and do not compromise the guarantee. So in case of doubt, just contact the technical assistance.

What other water facts are essential for my coffee?

In addition to the quality of the water, you should pay attention to some factors in the water used to make your coffee.

Temperature

Anyone who thinks that the water has to be boiling when passing through the powder is slightly mistaken. The truth is, when water is at 100°C, its boiling point, it loses all of its oxygen. In this way, you will be burning your coffee powder, which undergoes changes in flavor and quality.

The water must be very hot indeed; however, the “right” point is between 92º and 96º C. This guarantees that all the substances and nuances of the coffee pass into the drink. A “cold” water would not allow the extraction of some compounds, resulting in an unbalanced drink.

Method of preparation

The preparation method chosen and the way it requires water to be used can also interfere with the final product. There are ideal infusion times, and some methods even require you to blanch specific parts of the powder.

Coffee powder

The coffee powder makes a lot of difference in the entire brewing process. In addition to the quality of the grain, it is essential to keep in mind that grinding greatly influences the taste of the final product. 

A very fine powder can pass through the filter and create a small sludge at the bottom of the cup; too thick can retain more substance than it should if used in the wrong method.
