Fine Coffee Science explains ESPRESSO 4m Law in detail

The first Mistura (a mixture of coffee beans)

In Italy, espresso beans have to be mixed with at least five kinds of beans. For example, Erie espresso beans are composed of at least 11 kinds of coffee beans, and they also need to be fresh and roasted in Italian style, so ESPRESSO can only be pure and can not be called a single product.

The second Macinino (grinding method of coffee beans)

Ideally, when brewed with 7 grams of coffee powder, 25ml-35ml espresso can be brewed between 20 and 30 seconds. In order to achieve this ideal state, it is necessary to find out the most suitable grinding method. So you need a special bean grinder to make ESPRESSO coffee.

The third Macchina (espresso machine)

Can produce 90 ℃ plus or minus 5 ℃ water temperature, about 9Bar brewing pressure, but also can use 7 grams of coffee powder, through 20-30 seconds extraction to get a cup of about 25-35ml coffee beverage, the surface covered with a layer of gold foam (Crema) coffee machine is the coffee machine we need.

The fourth Mano (i.e. the coffee bar chef)

Without a coffee bar maker who can carefully adjust the grinding condition of coffee beans and is familiar with the performance of the coffee machine, he will not be able to brew delicious espresso. So it takes a professional barista who loves coffee very much to make the perfect ESPRESSO.
