What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complicated coffee machines in the world. It is made up of three main components. The bottom holds the water and the middle is a filter-basket with a metal filter.
This machine was a huge hit and helped spread the prosumer (home barista) espresso market. Its features include a low pressure pre-infusion, the 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're serious about your coffee and espresso, then you're aware that the pressure of your espresso maker is an important aspect in how your drinks turn out. You may be looking for an even layer of crema or perfect balance of flavor and acidity, the pressure of your espresso maker is crucial to making good espresso.
BARs (Barometric Pressure) refer to the amount of force exerted on the grounds of your coffee when your espresso machine is delivering its high-pressure water. The espresso machine is pushing hot water through the coffee grounds at a rate nine times Earth's current atmosphere pressure.
The pressure of your espresso machine is vital because it allows water to flow through the grounds of coffee at the proper speed and with the right intensity. If the pressure isn't high enough the flavors and oils aren't extracted properly. On the other hand, if the pressure is too high the water will be forced through the coffee grounds too quickly and you'll end up with a weak and over-extracted cup of espresso.
The pressure of your espresso machine can be adjusted by turning the screw found on the espresso pump. Commercial machines and high-end home machines come with rotary pumps with adjustable pressure. But for the more affordable home machines that use an oscillating pump, changing the pressure is not possible without getting into DIY hacks. However, companies like Cafflano are developing technology that utilizes Pascal's Principle to maintain pressure inside the portafilter throughout the making process.
Temperature
The temperature is one of the most important aspects for a great espresso shot. If the water is too hot, it may heat the coffee grounds and produce an over-extracted bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without scorching the grounds or excessively extracting.
The top espresso machines include a thermoblock which warms the water and keeps it at a stable temperature throughout the whole extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) which continuously monitors and adjusts the temperature of the water. This makes sure that the brewhead stays at the right temperature for extraction.
The majority of coffee drinkers are aware that the temperature of your espresso maker is a crucial factor in making a quality cup of coffee. The ideal temperature for espresso is between between 190 and 196. In order to get this temperature, your machine must have a quality thermoblock or thermocoil, and the boiler should be sized appropriately.
It is also essential to heat up your machine, portafilter and cup before making the espresso. Failure to preheat is one of the most common mistakes that can be committed by novice espresso makers. This is why it is important to always go through the instruction manual prior to making espresso for the first time.
Grind
A barista espresso machine must also have a variety of grind settings to give you the best ground coffee for espresso machine control over the final cup of coffee. Some machines have an analog pressure gauge which looks cool and can help you learn about your brewing techniques. Ideally, you want to achieve around nine bars of pressure, and keep that throughout the brewing cycle. This machine is getting close to reaching that goal.
A built-in burr mill is another excellent feature. This is a wonderful feature for people who are new to espresso since it will not require you to purchase a separate burr grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."
It's not as good as a stand-alone unit, however, it's a decent start and will have you well on your way to making quality espresso shots.

Water
Water can be a difficult thing to master. Finding the right balance is crucial. Too much and it can cause mineral deposits in the machine, but too little and you'll struggle to make a full cup of espresso.
The ideal water for espresso is soft and high in alkalinity. This is best budget espresso machine accomplished by using an water filter system that removes chlorine and puts an amount of total dissolving solids (TDS) to add some calcium and magnesium to the mix. This will provide a good balance between hardness and acidity, and prevent the necessity of decalcifying.
Using a high quality filtered water is essential for your machine's long-term health as well as the taste of the coffee it makes. A descaling product should be utilized on a regular basis according to the hardness and frequency of use of your machine. They are available in tab, liquid, or powder in a variety of hardware stores.
