It doesn’t matter if you’re seeking an even layer of crema, or the perfect balance of flavor and acidity the pressure of your espresso machine is crucial to making good espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts upon the grounds of the coffee while delivering high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the ground coffee at a an amount of nine times the Earth’s current atmospheric pressure.
The pressure of your machine is crucial because it allows water to flow through coffee grounds at the right speed and intensity. If the pressure is low the flavors and oils will not be extracted properly. On the other hand, if the pressure is too high the water will be pushed through the coffee grounds too quickly and you’ll end up with an over-extracted, weak cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw that is located on the espresso pump. Commercial and high-end home appliances have the rotary pumps that have adjustable pressure. For home-based machines that use a vibrating motor, it’s not possible to adjust the pressure without DIY hacks. Companies such as Cafflano however, are working on technology which uses Pascal’s Principle to ensure the pressure inside the portafilter throughout the beer making process.
Temperature
The temperature is one of the most important factors in brewing an excellent espresso shot. If the water is too hot, it may cause the coffee grounds to burn and produce an over-extracted bitter espresso. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water extract all the desired coffee flavors without burning the grounds or causing excessive extraction.
