Pressure
If you're serious about coffee and
espresso machine small, then you're aware that the pressure of your espresso maker is a crucial factor in how well your drinks are made. If you're looking for a thick layer of crema or perfect balance of acidity and flavor the pressure of your espresso machine is essential to making excellent espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine applies to the grounds of your coffee while delivering high-pressure water. The espresso machine is pushing hot water through the grounds of your coffee at nine times that of Earth's current atmosphere pressure.
The pressure of your espresso machine is important because it allows the water to move through the grounds of your coffee with the right speed and intensity. If the pressure is too low the flavors and oils that are dissolved aren't extracted properly. On the other hand, if the pressure is too high the water will be forced through the coffee grounds too quickly and you'll end up with an over-extracted, weak cup of espresso.
You can regulate the pressure of your espresso maker by adjusting the screw of the espresso maker. Commercial machines and some of the top-end home machines use rotary pumps that are adjustable. For the more affordable home machines that have the vibrating pump, altering the pressure is not possible without using DIY hacks. Companies like Cafflano however, are developing technology that uses Pascal's Principle to ensure the pressure inside the portafilter throughout the fermentation process.
Temperature
The temperature is among the most important factors in brewing an excellent espresso shot. The water that is too hot can scorch the grounds of the coffee, leading to a bitter coffee. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all of the desired coffee flavors without scorching the grounds or excessively extracting.
The best espresso machines include the thermoblock, or thermocoil which heats the water and keeps it at the same temperature throughout the extraction cycle.

Grind
A barista espresso machine must also offer a variety of grind settings for you to have the most control over your final cup of coffee. Some machines come with an analog pressure gauge, which is cool and can help you learn about your brewing techniques. Ideally, you should hit about nine bars of pressure, and keep that throughout the brewing cycle. Although this machine can't reach this mark, it's pretty close and will serve you well.
A built-in burr mill is a good feature. This feature is perfect for beginners since it eliminates having to buy an additional grinder. The stainless steel conical grinder features 18 settings, ranging from "coarse to fine."

It is vital to use water that is filtered and of good quality to ensure the health and flavor of your machine. Based on the type of use and the hardness of your machine, you should use descaling products regularly. They are available in liquid, powder or tab form at most hardware stores.
