BARs (Barometric Pressure) refer to the force that is applied to the grounds of your coffee when your espresso machine is delivering its high-pressure water.

For the more affordable home machines that have a vibrating pump, 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 maintain pressure within the portafilter during the making process.

Temperature

The temperature is among the most crucial factors to an espresso shot that is perfect. Hot water can cause burning of the grounds of the coffee, leading to a bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water extract all the desired coffee flavors without scorching the grounds or causing excessive extraction.

This will result in an optimal balance between hardness and alkalinity and will help avoid the need to decalcify your machine.

Using a high-quality filter water is crucial to your machine's overall health as well as the flavor of the coffee it produces.
