The pressure of your machine is crucial in brewing excellent coffee whether you’re looking for a dense layer or the perfect balance of acidity and flavor.BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of the coffee while delivering high-pressure water.

However, companies like Cafflano are working on technology that utilizes Pascal’s Principle to create maintained pressure in the portafilter during the beer making process.TemperatureTemperature is one of the most important factors in the perfect espresso shot. A hot water can burn the grounds of the coffee, resulting in a bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without scorching the grounds or over-extracting.The best espresso machines have the thermoblock, or thermocoil that heats water and keeps it at the same temperature throughout the extraction cycle.
