How to make a good coffee at home (according to science)

Coffee is almost certainly the most popular drink in the world after water. Although tea is preferred in many countries and cultures, it is the coffee that is bought and sold the most worldwide, generating passions and questions such as what is the best way to prepare coffee at home? Science has some answers to this question.

There are practical as many tricks for making coffee as there are people, and it is difficult for you to get two equal coffee machines. Each person likes to drink it in one way, be it espresso, short, long, with milk or alone. Regardless of your preferences, there is enough scientific evidence to affirm which coffee has more flavor.

Tap or mineral water? Hard or soft?


Which water is better for making coffee? It is one of the most recurring questions, since the temptation is simply to pull tap water. However, there are those who maintain that it is better to use mineral water. It is a debate that no longer makes sense since there are studies that settle the controversy.

According to science , to make coffee it is better to use "hard" water, that is, with a concentration of calcium and magnesium of between 17 and 85 milligrams per liter. It is recommended to check on the website of the company that supplies the water in your locality how much comes through the tap.
In most areas of Spain, tap water is more than good for making coffee. Thanks to the calcium and magnesium ions, a greater number of flavor-related particles are activated , making this drink more intense. You can still use mineral water if you want, although this has not been shown to provide any advantage.

Espresso vs. drip: which coffee maker makes better coffee


Leaving the capsules aside and focusing on espresso and drip, science already knows which coffee maker is best for making coffee with more flavor. To demonstrate this, it is necessary to take into account the two variables that affect the production process: pressure and time, in addition to others such as water that we have already discussed.

Here is a fundamental difference, and that is that in espresso coffee machines the coffee is much more pressed, while in the different methods to do it by drip it does not happen like that. This means that the best coffee machines for making intense coffee are those of the espresso type , which also have another advantage: when dripping, the water extracts flavor from the outside of the bean, but practically leaves the inside intact.

In addition, various studies have proven that espresso, due to its manufacturing method, contains a greater amount of caffeine and chlorogenic acid, two substances related to lower blood pressure, lower cholesterol and some more benefits for cardiovascular health.

A good way to simulate the effect of espresso on drip coffee is to do it manually, that is, pour water with a jug over the filter. It is recommended to let the water stand and distribute it evenly before starting to let it pass into the cup.
