Water and coffee. Which water should I use when preparing my coffee?
You often tend to underestimate the importance of the water you use when preparing coffee with a coffee machine. In this article, we will try to clarify the differences between using tap water, bottled water and filtered water to prepare your coffee.
Tap Water is an economical option, but it is not always the best choice for preparing high-quality coffee. In many areas, tap water contains chemicals, chlorine and limescale that can affect the taste of your coffee and compromise the extraction of aromatic substances from the coffee.
Another thing to consider is the hardness of the water. Hard water, containing high amounts of minerals such as calcium and magnesium, can produce a creamy and strong-tasting coffee. However, it can also cause limescale build-up in your coffee machine, impairing its efficiency and service life. For this reason, it is important to remove limescale from your machine regularly or use a water filter.
Bottle water is a popular alternative to tap water. However, not all bottled water is the same. Some waters, such as carbonated or mineral waters, can interfere with the taste of coffee and affect its quality. Certainly, natural mineral sources can add a touch of personality to your coffee, however it may be too strong for more delicate tastes.
Before using bottled water, read the label to understand the mineral content of the water. You will find information on PH, hardness, or other data on the labels of each brand.
Filtered water represents the midpoint between tap water and bottled water. By filtering tap water regularly from your filter device, you will remove impurities and chlorine, greatly improving the quality of your coffee.
However, filtered water is not always the ideal solution. Using too many or too few filters could change the taste of the water, making it too alkaline or acidic. We recommend using a water ioniser to balance the positive and negative ions in the water.
In the end, the best choice depends on your personal preferences and the quality of water available in your area. The knowledge we now have on the effects of water deduces that tap water is not the best choice. Between bottled water and filtered water, we can say that filtered water is average with good quality at an affordable price compared to bottled water. Remember, your coffee will only be good if you have put the right care into choosing the water you use, as well as choosing the capsule you like, from capsules compatible with Nespresso, Dolce Gusto or other brands.
