The machine was a huge hit and helped popularize home barista espresso. Features include a 2.2L steam boiler, low pressure pre-infusion & 9 bar brewing pressure.
Pressure
If you are an avid coffee drinker, you'll know that the pressure of your machine is a key factor in the quality of your drinks. The pressure of your machine is vital in brewing excellent coffee whether you're seeking a thick layer or a perfect balance of flavor and acidity.
BARs (Barometric Pressure) refer to the amount of force that is imposed on the coffee grounds when your espresso machine is pumping out its high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of your machine is vital because it allows water to pass through the coffee grounds at the right speed and intensity. If the pressure is too low the flavors and oils dissolved will not be extracted properly. On the other however, if the pressure is too high the water will be pushed through the coffee grounds too quickly and you'll end up with an over-extracted, weak cup of espresso.
You can control the pressure of your espresso maker by changing the screw on the espresso pump. Commercial and high-end home appliances have pumps that rotate with adjustable pressure. For home-based machines that utilize a vibration motor, it is not possible to adjust the pressure without DIY hacks. However, companies like Cafflano are developing technology that makes use of Pascal's Principle to maintain pressure in the portafilter during the beer making process.
Temperature
Temperature is one of the most crucial factors in the making of a good espresso shot. If the water is too hot, it could cause the coffee grounds to burn and result in an over-extracted bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all of the desired coffee flavors without burning the grounds or over-extracting.
The best espresso machines feature a thermoblock, or thermocoil that heats water and keeps it at a constant temperature throughout the extraction process. The Breville Barista Express, for example, has PID (Proportional Integral Derivative) system which constantly checks the temperature of the water and adjusts according to the need to ensure that the brew head stays at the ideal temperature to extract the coffee.
Most coffee lovers know that the temperature of your espresso maker is a crucial factor to brewing a high-quality cup of coffee. The ideal temperature for espresso is between between 190 and 196. To get this temperature, you need a machine with a good thermoblock, thermocoil, and a boiler that is appropriately sized.
In addition, it's essential to heat your portafilter, click here espresso machine, and cup prior to making the shot. Beginners often make the mistake of not heating their machine prior to making a shot. It is advisable to read your espresso machine's manual prior to attempting to try it for the very first time.
Grind
A barista espresso machine must also offer a variety of grind settings for you to have the most control over your final cup of coffee. Some machines have an analog gauge which looks cool and aids you improve your brewing abilities. Ideally, you want to reach around nine bars of pressure, and keep it throughout the brewing process.

This grinder isn't quite the same as a stand-alone device, but it's a good start and will have you on your way to making quality espresso shots. It's easy to clean, and you can even pause it during the grinding process to avoid making a mountain of grounds that will spill all over your portafilter on its way to the tamping.
This gorgeous and useful machine will let you feel like a barista from your home. It's an excellent choice for those who wish to be able to revisit the memories of pouring the microfoam into their morning coffee by locking a portafilter to the grouphead, and tamping with precision.

Water
Water is a difficult thing to master. The key is to find the right balance. Too much caffeine can cause mineral deposits to develop in your machine. But too little can result in a weaker cup of espresso.
The ideal water for espresso is low in hardness and high in alkalinity. It is best to use a water purifier that does not contain chlorine and adds a small amount (TDS) of total dissolved substances that add calcium and magnesium. This will create a balanced balance of alkalinity and hardness and reduce the necessity to decalcify your equipment.
It is vital to use water that is filtered and 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 use a descaling product on a regular basis. These products come in powder, liquid and tab forms and are available at many hardware stores.
