Understanding Espresso Machine Pressure
What does “bar” mean in espresso machines?
Before we delve into the differences, let’s clarify the terms “15 bar” and “20 bar”. In the context of espresso machines, the bar is a unit of measurement used to indicate pressure. It represents the force with which water is pushed through the coffee grounds to extract the flavors and oils. One BAR equals 14.7 PSI, meaning the natural atmospheric pressure at sea level. Consequently, the more BARS your espresso machine employs, the more pressure it exerts to force water through the coffee grounds.
Explaining the Significance of Pressure in Espresso Brewing
The pressure in an espresso machine is akin to the conductor in an orchestra orchestrating the extraction process. It influences the rate at which water passes through the coffee grounds, impacting the flavors, aromas, and the coveted crema atop your espresso shot.
The Ideal Pressure for Espresso
When making the perfect espresso, pressure plays a crucial role. Typically, coffee enthusiasts consider the ideal pressure to extract rich flavors from the coffee grounds around 9 bars. However, it’s important to note that maintaining consistent pressure throughout the brewing process is equally important. While a 15-bar or 20-bar machine may seem impressive, it doesn’t necessarily guarantee a better espresso. Excessive stress can often lead to over-extraction, resulting in a bitter or sour taste.
The Difference Between 15 Bar vs 20 Bar Espresso Machines
Now, let’s explore the differences between 15-bar and 20-bar espresso machines.
15 Bar Espresso Machines
A 15-bar espresso machine is a popular choice among home baristas. It offers sufficient pressure to produce a good cup of espresso. However, Opting for a 15-bar espresso machine is a solid choice for many, but it’s essential to acknowledge that it falls short of the pressure levels sought by professional baristas.
