Make an espresso with high-quality beans. It is important to have a good espresso machine to guarantee a drink that showcases the aromatic attributes of the coffee and produces a stable layer of crema on which the emulsified milk, used to make the latte art design, can rest.
The espresso is obtained by forcing a pressurized jet of hot water through a layer of seven grams of finely ground coffee for 25 seconds, yielding 30ml of concentrated coffee.
