WHAT WATER TO USE FOR COFFEE?

We rarely think about it, but water for coffee is of major importance in preparing a good beverage. Let's not forget, in fact, that coffee is made almost entirely of water. Why is the choice of water important? What water for good coffee and what water for an espresso machine? So many questions to which we provide you with the answers.

WHY IS THE CHOICE OF WATER FOR COFFEE IMPORTANT?

Do you know the percentage of water in a cup of coffee? Between 98.5 and 99%! You now understand better why the choice of water for coffee is crucial. You will certainly respond that water is colorless and tasteless. Yes, you are right about that. However, its chemical composition can vary completely, depending in particular on its origin. Indeed, some waters contain more minerals, limestone and calcium than others. Depending on the mineral or lime content for example, the mixture with coffee may create undesirable flavors and aromas. This is because certain components can interfere with the coffee extraction process. For example, water with a high calcium content will prevent your cup from having its true acidity. Using mineral water or tap water will completely transform the taste of your coffee. Know that the observation is the same, whatever bottled water you use, due to their different composition. So, which water should you choose to prepare your coffee?

OUR ADVICE FOR “PREPARING” YOUR COFFEE WATER

The first thing to know when choosing your coffee water is that the mineral content must be as low as possible. This allows for more aromas during infusion. Regarding limescale, it is necessary that your water also contains as little as possible, as you might expect. In addition to scaling up your machine, this will have the effect of altering the taste of the coffee. And, it is also preferable that the calcium content is low. But how to achieve this? Contrary to what some people may think, you absolutely should not boil water before using it. This would only increase the concentration of unwanted components. The easiest way is to use a quality water filter. The latter will reduce the percentage of calcium, chlorine, but also various metals present in the pipes (notably lead) that the water contains. If you use bottled water, make sure it contains as little calcium and dry residue as possible. So many tips to follow, to the letter, to fully enjoy your Araku coffee.
