What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines around the globe. It consists of three main components. The bottom holds the water, and the middle part is a filter-basket with a metal filter.
This machine was a huge hit and helped popularize the home barista espresso. It features a low pressure pre-infusion, a 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're an avid coffee drinker, then you will know that the pressure of your machine is an important element in the quality of your coffee. If you're looking for a thick layer of crema or the perfect balance of acidity and flavor the pressure of your espresso maker is the key to brewing perfect espresso.
BARs (Barometric Pressure) refer to the force exerted on the coffee grounds when your espresso machine is delivering its high-pressure water. Your espresso machine is pushing heated water through the coffee grounds at a rate nine times the Earth's current atmospheric pressure.
The pressure of your espresso machine is crucial as it allows the water to pass through the grounds of coffee at the proper speed and in the right amount. If the pressure is low, the oils and flavors aren't extracted properly. On the other however, if the pressure is too high the water will be forced through the coffee grounds too quickly, and you'll end up with an over-extracted, weak cup of espresso.
You can regulate the pressure of your espresso maker by adjusting the screw that is attached to the espresso pump. Commercial machines and a few high-end home appliances have pumps with rotary that can be adjusted. For the cheaper home machines that utilize the pump that vibrates, adjusting the pressure is impossible without engaging in DIY hacks. However, companies like Cafflano are developing technology that uses Pascal's Principle to create maintained pressure within the portafilter during the making process.
Temperature
Temperature is one of the most crucial factors in the perfect espresso shot. If the water is too hot, it will heat the coffee grounds and result in an over-extracted bitter drink. The ideal temperature for extraction is about 200 degrees Fahrenheit which allows the water to extract all the desirable coffee flavors without scorching the grounds or over-extracting.
The best espresso machines feature thermoblocks, also known as thermocoils that heats water and maintains it at an unchanging temperature throughout the extraction cycle. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system that continuously monitors the temperature of the water and adjusts as necessary, ensuring that the brew head remains at the ideal temperature for extraction.
Many coffee enthusiasts know that the temperature of your espresso machine is an important factor to brewing a high-quality cup of coffee. The ideal temperature for espresso is between between 190-196. To achieve this, your espresso machine must be equipped with a reliable thermoblock or thermocoil and the boiler needs to be sized appropriately.
Additionally, it is essential to heat your espresso maker, portafilter and cup before you make espresso. A failure to warm your espresso maker is one of the most common mistakes made by novice espresso makers. This is the reason why you should always study the instruction manual before using your espresso machine for the first time.
Grind
A barista espresso machine should provide a variety grind settings for you to have the most control over your final cup of coffee. Some machines include an analog pressure gauge, which is cool and can help you learn about your brewing techniques. You should aim to maintain the pressure of nine bars throughout the brewing process. This machine is close to getting to that point.
Another nice touch on this machine is that it has a built-in burr grinder. This is a great feature for newbies to espresso as it doesn't require them to purchase an additional burr grinder. The stainless steel conical grinder has 18 settings that range from "coarse to fine."
The grinder isn't as effective as a standalone but it will get you started on the path to make great espresso shots. It's easy to clean and you can stop it during the grinding process and avoid creating a pile of grounds that spill over your portafilter while on its way to making tamps.
This beautiful and functional machine will let you feel like a barista from your home. It's an excellent choice for those who wish to to look back at the fond memories of pouring microfoam into your morning cup of coffee by locking a portafilter to the grouphead, and tamping with precision.

Water
Water can be a difficult thing to master. Finding the right balance is essential. Too much and it can cause mineral deposits to form in your machine, while too little and you'll struggle get a rich cup of espresso.
The ideal espresso water has the lowest alkalinity and hardness level. It is recommended to use a filter which does not use chlorine and adds a small amount (TDS) of total dissolved substances to provide calcium and magnesium. This will create an optimal balance between hardness and alkalinity and will avoid the necessity to decalcify your equipment.
Using a high quality filtered water is essential for your machine's long-term health as well as the taste of the coffee it produces. Descaling products should be regularly used depending on the hardness and usage of your machine. They are available in liquid, powder and tab forms and can be found at most hardware stores.
