Pressure
If you're serious about your coffee and know that the pressure of your espresso coffee machine for home maker is an important factor in how your drinks are made. You may be looking for an even layer of crema, or the right balance of flavor and acidity the pressure of your espresso maker is the most important factor in brewing good espresso.
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 means that the espresso machine is pushing heated water through the coffee grounds at an amount of nine times the Earth's current atmospheric pressure.
The pressure of your professional espresso machine for home machine is crucial because it's what allows the water to move through the grounds of your coffee with the right speed and with the right intensity. If the pressure is too low the flavors and oils will not be extracted properly. On the other side, 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, diluted 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 have rotating pumps that can be adjusted in pressure. However, for the less expensive home appliances that utilize the vibrating pump, altering the pressure is not possible without getting into DIY hacks. Companies such as Cafflano however, are developing technology which uses Pascal's Principle in order to maintain the pressure inside the portafilter throughout the brewing process.
Temperature
Temperature is one of the most important aspects in the perfect espresso shot. The water that is too hot can scorch the grounds of coffee, which can result in bitter drink. 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 excessively extracting.

The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. In order to achieve this, your machine must be equipped with a reliable thermoblock or thermocoil and the boiler needs to be of the right size.

Some machines include an analog pressure gauge that looks cool and can help you learn about your brewing skills. You should aim to maintain the pressure of nine bars throughout the brewing process. This machine is close to the goal.
A built-in grinder is another excellent feature. This is an excellent feature for those who are new to espresso because it will not require you to pay for a separate burr grinder. The grinder is an stainless steel conical unit with 18 settings, ranging from "coarse" to "fine."

The perfect espresso water has a low hardness and alkalinity level. This is best achieved by using an water filter system that bypasses all chlorine and adds back a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will create a balanced balance of hardness and alkalinity and will help avoid the necessity to decalcify your equipment.
It is vital to make sure you use water that has been filtered to a high end espresso machine quality espresso machine for the health and taste of your machine. Based on the type of use and the hardness of the machine, you should use descaling products regularly. These products come in powder, liquid and tab forms and are available at most hardware stores.
