Espresso is a method of brewing coffee. Hot water is forced, under pressure, through finely ground and compacted coffee. This is a primary point of difference – generally, espresso machines operate at 9 bars, or 130.5 psi. Compare this to the 60 odd psi that fills a car tyre, and you start to get the picture.
So, intense pressure and a very high ratio – what do we get in the cup?
Espresso is a concentrated extract of the soluble oils, acids, and sugars found in coffee. When made well, espresso has a balance of intense acidity and deep sweetness, with a big body and thick mouthfeel.
The barista handles many aspects of espresso making – dose, yield, time, temperature, pressure, pressure profiling… it is easy to get lost in a sea of variables. Espresso brewing is a science, so tiny changes can have a profound impact on the final product. Baristas manipulate these variables to get the best out of a particular coffee.
