BARs (Barometric Pressure) refer to the amount of force applied to the coffee grounds when your espresso machine is pumping out its high-pressure water. 9 BARs indicates that your espresso machine is pushing heated water through the ground coffee at a a rate of nine times the current atmospheric pressure.

The pressure of the espresso machine is crucial because it allows the water to move through the grounds of the coffee at the right speed and in the right amount. If the pressure is too low, the flavors and oils dissolved aren't extracted properly. If the pressure is too low the dissolved flavors and oils won't be extracted properly.

The pressure of your espresso machine can be controlled by adjusting the screw found on the espresso pump. Commercial machines and some of the top-end home appliances use rotary pumps that are adjustable. For the cheaper home machines that have a vibrating motor, it is impossible to adjust the pressure without hacks. However, companies like Cafflano are developing technology that uses Pascal's Principle to maintain pressure within the portafilter during the making process.

Temperature

Temperature is among the most important aspects in the making of a good espresso shot. If the water is too hot, it will ignite the coffee grounds and create an over-extracted bitter brew. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all the desired flavors of coffee without scorching the grounds or over-extracting.

The best Espresso machine espresso machines include the thermoblock, or thermocoil that heats water and maintains it at a constant temperature throughout the extraction process. The Breville Barista Express, for example, has a PID (Proportional Integral Derivative) system that constantly monitors the temperature of water and adjusts according to the need so that the brew head remains at a perfect temperature for extraction.

It is advisable to read your espresso machine's manual before you begin using it for the first time.

Grind

A barista machine ought to give you a range of grind settings to ensure that you have the maximum control over the final cup of espresso. Some machines include an analog pressure gauge, that is stylish and can help you learn about your brewing skills.

The best espresso water has the lowest alkalinity and hardness level. This is best achieved using an effective water filtering system that eliminates chlorine and brings back a small amount of total dissolving solids (TDS) to add some calcium and magnesium to the mix. This will help you achieve an ideal balance between hardness and acidity and avoid the necessity of decalcifying.

Using a high quality filtered water is crucial to your machine's overall health and the flavor of the coffee it makes. Descaling products should be used on a regular basis according to the hardness and usage of your machine.
