What to Look For in a Barista Espresso Machine

This machine was a huge success and helped to popularize home barista espresso. Features include a 2.2L steam boiler, a low pressure pre-infusion, and 9 bar pressure for brewing.

Pressure

If you're serious about your coffee and know that the pressure of your espresso machine is an important factor in how your drinks are made. Whether you're looking for a thick layer of crema or the right balance of acidity and flavor the pressure of your espresso machine is crucial to making perfect espresso.

BARs (Barometric pressure) is the force your espresso machine exerts on grounds of coffee while pumping high-pressure water. 9 bar espresso machine BARs means that the espresso machine is pushing heated water through the coffee grounds at the rate of nine times the current atmospheric pressure.

The pressure of your machine is vital because it allows water to pass through the coffee grounds at the proper speed and intensity. If the pressure is low the oils and flavors will not be extracted correctly. On the other however, if the pressure is too high, the water will be forced through the coffee grounds too fast and you'll end up with a weak, over-extracted cup of espresso.

You can control the pressure of your espresso maker by changing the screw on the espresso pump. Commercial machines and some high-end home appliances have rotating pumps that can be adjusted. For the cheaper home machines that utilize a vibration motor, it's impossible to adjust the pressure with DIY hacks. However, companies like Cafflano are working on technology that makes use of Pascal's Principle to create maintained pressure inside the portafilter throughout the brewing process.

Temperature

Temperature is one of the most important aspects in the making of a good espresso shot. A hot water can burn the coffee grounds, resulting in a bitter brew. The ideal extraction temperature is 200 degrees Fahrenheit which allows the water to extract all of the desired flavors of coffee machines espresso without scalding the grounds or over-extracting.

The Best ground coffee for espresso Machine espresso machines will have a thermoblock or thermocoil that is used to heat the water and keep it at a stable temperature throughout the entire extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system which constantly checks the temperature of the water and adjusts according to the need making sure that the brewhead remains grinding process to avoid creating a mountain of ground that will fall onto your portafilter on its way to the tamping.

This beautiful and functional machine will let you feel like a barista from your home. It's a great choice for those who wish to to revisit the moments of pouring microfoam into their morning coffee and locking a portafilter in the grouphead, and then tamping with precision.

The perfect water for espresso is low in hardness and high in alkalinity. This is best achieved by using a water filter system which eliminates chlorine and brings back a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will result in a balanced balance of alkalinity and hardness and help avoid the necessity to decalcify your equipment.

It is important to use water filtered of high-quality for the health and taste of your machine. Based on the type of use and the hardness of the machine, you should make use of descaling products regularly.
