What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines in the world. It is composed of three main parts. The bottom is where the water goes and the middle contains the filter-basket.
This machine was a big success and helped to popularize home barista espresso. Its features include a low pressure pre-infusion, the 2.2L boiler and brewing pressure of 9 bar.
Pressure
If you are a coffee lover, you'll know that the pressure of your machine is a major factor in the quality of your coffee. The pressure of your machine is vital for making great coffee, whether you're seeking a thick layer or the perfect balance of acidity and flavor.
BARs (Barometric pressure) is the force your espresso machine exerts upon the coffee grounds while delivering high-pressure water. Your espresso machine is pushing heated water through the grounds of your coffee at nine times the Earth's current atmospheric pressure.
The pressure of your espresso machine is important as it allows the water to flow through the grounds of your coffee with the right speed and in the right amount. If the pressure is too low, the flavors and oils that are dissolved will not be extracted properly. 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 and over-extracted cup of espresso.
You can regulate the pressure of your espresso maker by changing the screw that is attached to the espresso pump. Commercial machines and top-end home machines feature rotary pumps with adjustable pressure. For the less expensive home machines, which use a vibrating motor, it's impossible to adjust the pressure with DIY hacks. However, companies like Cafflano are working on technology that utilizes Pascal's Principle to maintain pressure inside the portafilter throughout the brewing process.
Temperature
The temperature is among the most critical factors for a great espresso shot. Hot water can cause burning of the grounds of the coffee, resulting in a bitter drink. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all the desired coffee flavors without scorching the grounds, or over-extracting.
The top espresso machines come with a thermoblock, or thermocoil which heats the water and maintains it at an even temperature throughout the extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) which constantly monitors and adjusts the temperature of water. This ensures that the brewhead is at the correct temperature for extraction.
Most coffee lovers know that the temperature of the espresso machine is vital to brewing a great cup of coffee. The ideal temperature for espresso is between between 190-196. To attain this, you will require a machine with a good thermoblock, thermocoil or thermoblock and a boiler that is properly sized.
It is also crucial to pre-heat your espresso maker, portafilter, and cup prior to making the espresso. Inability to heat your equipment is among the most common errors made by beginner espresso makers. This is why you should always read the instruction manual before making espresso for the first time.
Grind
A barista machine should give you a range of grind settings so you can have the greatest control over the final cup of espresso. Some machines include an analog pressure gauge, that looks cool and can help you learn about your brewing skills. The goal is to maintain a pressure of nine bars throughout the brewing process. This machine is very close to hitting that target.
A built-in burr mill is another excellent feature. This feature is great for those who are new to the field because it avoids the need for an additional grinder. The stainless steel conical grinder has 18 settings, which range from "coarse to fine."
This grinder isn't as good as a standalone unit, but it will get you started on the right track to making great espresso shots. It's easy to clean, and you can stop the grinder during the grinding process to avoid accumulating an overwhelming amount of ground on your portafilter while it is being crushed.

Water
Water is a tricky thing to master. Finding the right balance is key. Too much caffeine can cause mineral deposits to form inside your machine. But too little will result in an espresso cup that is weaker.
The ideal water for espresso has low alkalinity and hardness level. This can be achieved with an effective water filtering system that eliminates chlorine and brings an 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 prevent the necessity of decalcifying your equipment.
Using high-quality filtered water is vital to your machine's longevity health as well as the flavor of the coffee it produces. Descaling products must be regularly used, depending on the hardness and usage of your machine. These products are available in tab, liquid, or powder form at most hardware stores.
