that's wrong.

Espresso is coffee that is made from pushing steam through finely ground coffee. It is pulled for roughly 23 seconds, and most barista time their shots every hour or 2 to ensure that their grind is correct.

little input .. correct to say that "pushing Steam' but need to consider to pressure bar ....

normal will be 12 bar .. to 16 bar ...

as for me ... starbuck or even some 5 star hotel coffe outlet cannot come " Close " to what i prepared for myself
( nespresso capsule machine N90 )

exspresso "tech" is to have high pressure bar machine .. and good coffee bean and most of all ...drinks it one go while is still 'warm"

so .. those people who go to starbuck or some luxury coffee outlet are NOT able to enjoy the real of Expresso ...cos
... they wanted to be seen by others or killing time or to spend time to so called "enjoy" the coffee....
