Essential points for make a creamy espresso coffee:

Coffee quality, understood as the chosen brand and blend.
Grinding, the more humid the air, the finer it must be.
Quantity of powder for each coffee, from 7 to 8 grams.
Pressing the coffee into the arm of the machine in a force of 12 kg should be applied.
Machine working pressure, between 8.5 and 9.5 bar, the ideal one must be around 9 atmospheres.
Water temperature, ideally it must be around 88/90 ° C.
Coffee brewing time, the water must flow inside the powder, with a process called percolation, from 23 to 25 seconds.
Daily cleaning of the filter holder.

In the typical volume of a cup of espresso coffee for 25 – 30 millilitres, the foam rappresents a further 10% of the total volume. The coffee foam or “crema” is made up of the liquid coffee content and the carbonic anhydride microbubble with a membrane made of grassi, protein, polyphenol, acidi, glycide and microglobule of oil.

The amount of foam depends on the type of coffee, it is great in coffee Robusta and minor in Arabica, with intermediate grade in the miscellaneous variety.

In the cup, the differences are also quite evident. Arabica coffee has more natural sugars, so it has a sweeter taste, smooth taste and slightly acidic. On the other hand, Robusta is bitter and more pronounced on the palate, ideal for those who appreciate stronger and more intense coffee.

Furthermore, Arabica is more aromatic, with fruit or sweet notes. Robusta has a denser aroma. In this sense, some Robusta varieties are appreciated in espressos, as they provide a deeper aroma and a denser cream.

Caffeine concentration:

In Robusta has almost twice as much caffeine (2.2%) when compared to Arabica (1.2%) and, for this reason, it is considered a strong drink.

After knowing all this, you have only one question in your head : Which is the best?

We cannot say that one is better than the other. In fact it all depends on your taste buds.
Overall, Arabica is more valuable and recognized for offering a richer experience in flavors and aromas. Therefore, 100% Arabica beans are used in the production of fine coffees, “So called: Specialty and Gourmet coffees”.

Robusta, on the other hand, is valued for the composition of blends by the instant coffee industry.
