BARs (Barometric Pressure) refer to the force exerted on the coffee grounds when your espresso machine is delivering its high-pressure water. The espresso machine is pushing heated water through the grounds of the coffee at a rate nine times the current atmospheric pressure.
The pressure of the espresso machine is crucial as it allows the water to move through the coffee grounds at the right speed and intensity. If the pressure is low, the oils and flavors won't be extracted properly. On the other hand, if the pressure is too high the water will be pushed through the coffee grounds too fast and you'll end with a weak, over-extracted cup of espresso.

For the more affordable home machines that utilize the pump that vibrates, adjusting the pressure isn't possible without engaging in DIY hacks. However, companies like Cafflano are working on technology that uses Pascal's Principle to create maintained pressure in the portafilter during the beer making process.
Temperature
Temperature is one of the most crucial factors in the perfect espresso shot. A hot water can burn the grounds of coffee, which can result in a bitter coffee. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all the desired flavors of coffee without scalding the grounds or over-extracting.

The ideal water for espresso has an alkalinity and hardness that is low level. This is best achieved using an effective water filtering system that removes chlorine and puts back a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will ensure an optimal balance between hardness and acidity and also avoid check here the necessity of decalcifying.
It is essential to use water that is filtered and of good quality to ensure the health and taste of your machine. Descaling products should be regularly used, depending on the hardness and usage of your machine. They are available in tab, liquid or powder form at a majority of hardware stores.
