BARs (Barometric pressure) is the force your espresso machine exerts on the coffee grounds while delivering high-pressure water. The espresso machine is pushing hot water through the coffee grounds at a rate nine times the current atmospheric pressure.

The pressure of your machine is important because it allows water to pass through coffee grounds at the right speed and intensity. If the pressure is low the flavors and oils aren't extracted properly. On the other contrary, if pressure is too high the water will be forced through the coffee grounds too fast and you'll end up with a weak and over-extracted cup of espresso.

The pressure of your espresso machine can be adjusted by turning the screw that is located on the espresso pump. commercial espresso machine machines and a few high-end home appliances use the rotary pumps, which are adjustable. For the less expensive home machines that utilize a vibration motor, it's not possible to adjust the pressure without hacks. However, companies like Cafflano are developing technology that uses Pascal's Principle to maintain pressure inside the portafilter throughout the brewing process.

Temperature

Temperature is one of the most crucial factors in the perfect espresso shot. If the water is too hot, it will heat the coffee grounds and produce an over-extracted bitter coffee. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without burning the grounds or over-extracting.

The top espresso machines come with a thermoblock, or thermocoil, which heats water and keeps it at the same temperature throughout the extraction cycle.

The perfect water for espresso is soft and high in alkalinity. It is best to use a water filter that removes chlorine and adds a small amount (TDS) of total dissolved substances that add calcium and magnesium. This will give you an optimal balance between acidity and hardness, and prevent the need to decalcify.

Using a high quality espresso machine filtered water is crucial to your machine's overall health and the taste of the coffee it makes. Depending on the use and the hardness of your machine, you should use a descaling product on a regular basis.
