What to Look For in a Barista Espresso Machine

The espresso machine is one of the most complex coffee machines around the globe. It consists of three main parts. The base holds the water and the middle is a filter-basket with a metal filter.

This machine was a huge success and helped popularize the prosumer (home barista) espresso market. Features include a low pressure pre-infusion, a 2.2L boiler and brewing pressure of 9 bar.

Pressure

If you are an avid coffee drinker, then you will know that the pressure of your espresso machine is a major factor in the quality of your drinks. If you're looking for a thick layer of crema or the perfect balance of flavor and acidity the pressure of your espresso machine is the key to brewing excellent espresso.

BARs (Barometric pressure) is the force your espresso machine applies to the coffee grounds while delivering high-pressure water. Your espresso machine is pushing hot water through the grounds of coffee at nine times that of Earth's current atmosphere pressure.

The pressure of your machine is important because it allows the water to pass through the coffee grounds at a proper speed and intensity. If the pressure is too low the flavors and oils that are dissolved won't be 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 with a weak, over-extracted cup of espresso.

The pressure of your espresso machine can be controlled by adjusting the screw found on the espresso machine coffee pump. Commercial machines as well as some high-end home appliances use the rotary pumps, which are adjustable. For home machines that are less expensive that have a vibrating motor, home espresso Machine it's impossible to adjust the pressure without hacks. Companies like Cafflano however, are developing technology that uses Pascal's Principle to ensure the pressure inside the portafilter throughout the brewing process.

Temperature

Temperature is among the most important factors in a perfect espresso shot. A hot water can burn the grounds of the coffee, resulting in a bitter brew. The ideal temperature for extraction is around 200 degrees Fahrenheit, which allows the water to extract all the desirable coffee flavors without burning the grounds or over-extracting.

The best espresso machines feature a thermoblock, or thermocoil which warms the water and keeps it at a steady temperature throughout the whole extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system which constantly monitors the temperature of water and adjusts it as needed making sure that the brewhead remains at the perfect temperature to extract the coffee.

The majority of coffee drinkers know that the temperature of the espresso maker is crucial to a good cup of coffee. The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit. To get this temperature, your machine should have a high-quality thermoblock or thermocoil, and the boiler should be sized appropriately.

It is also essential to heat up your machine, portafilter, and cup prior to making espresso. Beginners often make the mistake of not preheating their machines. This is the reason you should always read the instruction manual before using your espresso maker for the first time.

Grind

A barista machine should give you a variety of grind settings so you have the maximum control over the final cup of espresso. Some machines have an analog pressure gauge that is stylish and can help you learn about your brewing skills. The ideal goal is to get around nine bars of pressure, and keep this throughout the entire brewing process. This machine is close to reaching that goal.

Another nice touch on this machine is its built-in burr grinder. This is a fantastic feature for newbies to espresso as it doesn't require them to shell out money for an additional burr grinder. The grinder is a stainless steel conical device with 18 settings, ranging from "coarse" to "fine."

This grinder isn't as good as a standalone unit, but it will get you to the right path to making excellent espresso shots. It's easy to clean and you can also pause it during the grinding process this will help you avoid creating a mountain of ground that can spill over your portafilter while on its way to tamping.

This is a beautiful and practical machine that allows you to experience the excitement of being a barista at home. It's an excellent choice for anyone who wants to be able to look back at the moments of pouring microfoam into your morning cup of coffee or locking a portafilter into the grouphead, and then tamping with precision. A bean-to-cup machine is an excellent choice for those looking for a simple and convenient solution.

Water

Water can be a challenging thing to master. Finding the right balance is vital. Too much can cause mineral deposits to form inside your machine. Too little could result in less of an espresso.

The ideal water for espresso has the lowest alkalinity and hardness level. It is recommended to use a water filter that removes chlorine and adds a small amount (TDS) of total dissolved substances to add calcium and magnesium. This will give you an ideal balance between acidity and hardness and will also prevent the need to decalcify.

Using a high quality filtered water is vital to your machine's long term health and the flavor of the coffee it produces. Depending on the use and the hardness of your machine, you should make use of descaling products on a regular schedule. These products are available in tab, liquid or powder in a variety of hardware stores.

The Breville Barista Express is a premium, high-end home espresso machine designed to bring the cafe experience inside your home. It offers more advanced features than other machines for beginners that are geared towards coffee enthusiasts who wish to improve their technique and perfect their craft. The thermocoil heating system with integrated PID controller that is centered on the group head makes it easy to control your brewing temperature. This is a huge advantage over other models at the entry level which need you to spend much time "temperature-surfing" to ensure an even espresso shot.
