Pressure
If you're an avid coffee drinker, you'll realize that the pressure of your machine is a crucial factor in the quality of your beverages. Whether you're looking for a thick layer of crema or the right balance of flavor and acidity the pressure of your espresso machine is crucial to making great espresso.
BARs (Barometric pressure) is the force your espresso machine exerts upon the grounds of your coffee while delivering high-pressure water. 9 BARs means that your espresso machine is forcing heated water through the coffee grounds at a rate of nine times the current atmospheric pressure.
The pressure of your espresso machine is important because it allows the water to move through the grounds of coffee at the proper speed and in the right amount. If the pressure is too low, the oils and flavors will not be extracted correctly. If the pressure is too low, the flavors and oils dissolved will not be extracted properly.
You can regulate the pressure of your espresso maker by adjusting the screw on the espresso pump. Commercial and high-end home machines have the rotary pumps that have adjustable pressure. For home machines that are less expensive that use a vibrating motor, it's not possible to alter the pressure without DIY hacks. However, companies like Cafflano are working on technology that makes use of Pascal's Principle to maintain pressure within the portafilter during the making process.
Temperature
The temperature is among the most critical factors for a great espresso shot. Too hot water can burn the grounds of the coffee, leading to a bitter coffee. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all of the desired coffee flavors without burning the grounds or excessively extracting.

Grind
A barista machine ought to give you a variety of grind settings, so that you can have the most control over your final cup of espresso. Some machines include an analog gauge which looks cool and aids you to improve your brewing skills.

Water
Water is a difficult thing to master. Finding the right balance is essential. Too much caffeine can cause mineral deposits to build up in the machine, but too little and you'll struggle to get a good cup of espresso.
The ideal water for espresso has low alkalinity and hardness level. It is recommended to use a water filter that does not contain chlorine and adds a tiny amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will result in a balanced balance of alkalinity and hardness, and will prevent the necessity of decalcifying your machine.
It is crucial to use water that is filtered and of high quality for the health and flavor of your machine. Descaling products should be regularly used based on the strength and use of your machine.
