What to Look For in a Barista Espresso Machine
The espresso machines home machine is among the most complex coffee machines available. It is comprised of three major components. The bottom holds the water while the middle is a basin for filtration with a metal filter.

Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso machine is an essential factor in how well your drinks come out. The pressure of your machine is crucial in brewing excellent coffee whether you want a thick layer or a perfect balance of acidity and flavor.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts on grounds of your coffee while delivering high-pressure water. 9 BARs indicates that your espresso machine is forcing heated water through the ground coffee at a the rate of nine times the current atmospheric pressure.
The pressure of your espresso machine is vital because it's what allows the water to pass through the grounds of coffee at the proper speed and intensity. If the pressure isn't high enough, the oils and flavors will not be extracted correctly. On the other however, if the pressure is too high the water will be pushed through the coffee grounds too quickly, 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 found on the espresso pump. Commercial machines and high-end home machines come with rotating pumps that can be adjusted in pressure. For home-based machines that utilize a vibration motor, it's impossible to adjust the pressure without DIY hacks. Companies like Cafflano, however, are developing technology that uses Pascal's Principle to ensure pressure within the portafilter throughout the beer making process.
Temperature
The temperature is among the most critical factors for an travel espresso maker shot that is perfect. If the water is too hot, it may ignite the coffee grounds and result in an over-extracted bitter coffee. The ideal extraction temperature is about 200 degrees Fahrenheit, which allows the water to extract all of the desired flavors of coffee without scorching the grounds, or over-extracting.
The best espresso machine espresso machines will have a thermoblock or thermocoil which will heat the water, and keeps it at a stable temperature throughout the entire extraction cycle. The Breville Barista Express has a PID system (Proportional Integral Derived) that constantly monitors and adjusts the temperature. This ensures that the brewhead is at the correct temperature for extraction.
Most coffee lovers know that the temperature of the espresso machine is essential to making a great cup of coffee.

Grind
A barista espresso machine should provide a variety grind settings to give you the best control over your final cup of coffee. Some machines have an analog pressure gauge, which looks cool and can help you learn about your brewing abilities.

A built-in burr mill is a good feature. This feature is perfect for novices because it doesn't mean having to purchase an additional grinder. The stainless steel conical grinder comes with 18 settings, ranging from "coarse to fine."

The perfect water for espresso is low in hardness and high in alkalinity. It is best to use a water purifier that bypasses chlorine and adds a tiny amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will ensure the right balance between hardness and acidity and avoid the need to decalcify.
Using a high-quality filter water is crucial to your machine's long term health as well as the taste of the coffee it produces.
