What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines around the world. It has three main components. The bottom holds the water and the middle is a filtration basin with a metal filter.
This machine was a major hit and helped popularize home barista espresso. Features include a 2.2L steam boiler, a low pressure pre-infusion & 9 bar brewing pressure.
Pressure
If you are an avid coffee drinker, you will know that the pressure of your machine is an important factor in the quality of your coffee. Whether you're looking for a thick layer of crema or perfect balance of flavor and acidity the pressure of your espresso maker is the most important factor in brewing excellent espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on coffee grounds while delivering high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the coffee grounds at the rate of nine times the Earth's current atmospheric pressure.
The pressure of your espresso machine is crucial as it allows the water to flow through the grounds of your coffee with the right speed and intensity. If the pressure isn't high enough, the oils and flavors 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 a weak, over-extracted cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw located on the espresso pump. Commercial machines and high-end home machines come with rotating pumps that can be adjusted in pressure. For the cheaper home machines that use a vibrating motor, it's not possible to adjust the pressure with DIY hacks. Companies like Cafflano, however, are developing technology that utilizes Pascal's Principle in order to maintain pressure in the portafilter during the beer making process.
Temperature
The temperature is one of the most critical factors for an excellent espresso shot. If the water is too hot, it can heat the coffee grounds and create a bitter espresso. The ideal extraction temperature is around 200 degrees Fahrenheit which allows the water to extract all the coffee's desirable flavors without scorching the grounds or over-extracting.
The best espresso machines feature the thermoblock, also known as a thermocoil, which heats water and maintains it at a constant temperature throughout the extraction cycle. The Breville Barista Express has a PID system (Proportional Integral Derived) which continuously monitors and adjusts the temperature of water. This ensures that the brewhead remains at the ideal temperature for extraction.
Most coffee lovers are aware that the temperature of the espresso maker is essential to making a great cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190-196. To achieve this, your espresso machine must be equipped with a reliable thermoblock or thermocoil and the boiler must be properly sized.
It is also essential to pre-heat your espresso maker, portafilter and cup before making espresso. Inability to heat your equipment is one of the most common errors committed by novice espresso makers. It is advisable to read your espresso machine's manual prior to attempting to use it for the first time.
Grind
A barista espresso machine should provide a variety grind settings to give you the greatest control over the final cup of coffee. Some machines include an analog gauge which looks cool and aids you improve your brewing skills. You should aim to maintain the pressure of nine bars throughout the brewing cycle. While this machine doesn't hit the mark, it's quite close and will serve you well.
A built-in grinder is another great feature. This feature is ideal for beginners because it eliminates the need for a separate grinder. The stainless steel conical grinder has 18 settings, ranging from "coarse to fine."
This grinder isn't as good as a stand-alone unit, however, it's a decent beginning and will get you on the path to making quality espresso shots. It's easy to clean, and you can stop the grinder during the process of grinding to avoid accumulating a huge amount of ground in your portafilter when it is being stamped.
This gorgeous and practical machine will allow you to enjoy the barista experience in your own home. This is an excellent option for anyone who would like to recall the thrill of pouring microfoam in their morning coffee while locking the portafilter in the grouphead's head and tamping the coffee with precision. For those who want convenience, a bean-to- cup machine could be a better choice.
Water
Water is a tricky thing to master. The trick is finding the right balance. Too much can cause mineral deposits to form in the machine, but too little and you'll struggle get a good cup of espresso.
The perfect water for espresso is soft and high in alkalinity. This is best accomplished by using an effective water filtering system that bypasses all chlorine and adds back in a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will result in an optimal balance between alkalinity and hardness, and will help avoid the necessity to decalcify your equipment.
Using a high-quality filter water is essential to your machine's overall health as well as the flavor of the coffee it produces. Depending on the use and hardness of your machine, you should make use of a descaling product on a regular basis. They are available in liquid, powder and tab forms espresso maker and can be found in the majority of hardware stores.

The thermocoil heating system with an integrated PID controller located on the group head that is actively heated which makes it simple to regulate your brewing temperature. This is a huge advantage over other entry-level models that require much time "temperature-surfing" to get consistent espresso shots.
