Pressure
If you're serious about coffee and espresso, then you're aware that the pressure of your espresso maker is an important factor in how well your drinks taste. You may be looking for an even layer of crema or the perfect balance of acidity and flavor, the pressure of your espresso machine is the key to brewing excellent buy espresso machine.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts upon the coffee grounds while delivering high-pressure water. 9 BARs means that the pro espresso machine machine is pushing heated water through the coffee grounds at the rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is crucial because it allows water to pass through coffee grounds at a proper speed and intensity. If the pressure is low the flavors and oils will not be extracted correctly. If the pressure is too low the flavors and oils that are dissolved will not be extracted correctly.
The pressure of your espresso machine can be adjusted by turning the screw located on the espresso pump. Commercial machines and some high-end home appliances use pumps with rotary that can be adjusted. But for the more affordable home machines that utilize an oscillating pump, changing the pressure isn't possible without using DIY hacks. Companies like Cafflano however, are working on technology that utilizes Pascal's Principle in order to maintain the pressure inside the portafilter throughout the beer making process.
Temperature
The temperature is one of the most crucial factors to an espresso shot that is perfect. Hot water can cause burning of the coffee grounds, resulting in bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all desired coffee flavors without scorching the grounds or over-extracting.

It is best to use a water filter that bypasses chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will result in a balanced balance of hardness and alkalinity and will prevent the necessity of decalcifying your machine.
It is vital to use water filtered of high-quality for the health and flavor of your machine. Descaling products should be utilized on a regular basis, depending on the hardness and use of your machine. They are available in powder, liquid or tab in a variety of hardware stores.
