What to Look For in a Barista Espresso Machine

The pressure of your espresso machine is important because it's what allows the water to flow through the coffee grounds at the right speed and with the right intensity.

The pressure of your espresso machine can be controlled by adjusting the screw that is located on the espresso pump. Commercial machines and high-end home machines come with the rotary pumps that have adjustable pressure.

However, companies like Cafflano are working on technology that uses Pascal's Principle to create maintained pressure inside the portafilter throughout the brewing process.

Temperature

Temperature is among the most important factors in a perfect espresso and filter coffee machine shot.
