What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines in the world. It is comprised of three primary components. The base holds the water and the middle part is a filter-basket with a filter made of metal.
The machine was a huge hit and helped popularize the home barista espresso. It features a 2.2L steam boiler, a low pressure pre-infusion and 9 bar brewing pressure.
Pressure
If you're an avid coffee drinker, you'll be aware that the pressure of your machine is a key factor in the quality of your drinks. The pressure of your machine is vital to brewing 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 grounds of the coffee while delivering high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the ground coffee at 9 times the current atmospheric pressure.
The pressure of your espresso machine is crucial because it allows the water to flow through the grounds of the coffee at the right speed and with the right intensity. If the pressure is too low, the dissolved oils and flavors won't be extracted properly. On the other contrary, if 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.
You can regulate the pressure of your espresso maker by adjusting the screw that is attached to the espresso pump. Commercial machines and top-end home machines come with rotating pumps that can be adjusted in pressure. For the more affordable home machines that have the vibrating pump, altering the pressure is difficult without involving DIY hacks. However, companies like Cafflano are working on technology that uses Pascal's Principle to maintain pressure in the portafilter during the fermentation process.
Temperature
Temperature is among the most crucial factors in a perfect espresso shot. Hot water can cause burning of the grounds of coffee, which can result in bitter coffee. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without scorching the grounds or over-extracting.
The top espresso machines have a thermoblock or thermocoil which is used to heat the water and keep it at a steady temperature throughout the whole extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) which constantly monitors and adjusts the temperature of the water. This makes sure that the brewhead stays at the perfect temperature for extraction.
Most coffee lovers know that the temperature of an espresso machine is crucial to a good cup of coffee. The ideal temperature for brewing espresso is between 190 to 196 degrees Fahrenheit. To attain this, your machine must have a quality thermoblock or thermocoil, and the boiler should be properly sized.
It is also crucial to heat up your machine or portafilter before making shots. A failure to warm your espresso maker is among the most common mistakes that can be committed by novice espresso makers. It is advisable to read your espresso machine's manual before you use it for the first time.
Grind
A barista espresso machine should also have a variety of grind settings to give you the most control over the final cup of coffee. Some machines come with an analog gauge which looks cool and aids you improve your brewing abilities. Ideally, you should reach around nine bars of pressure and keep this throughout the entire brewing process. This machine is very close to getting to that point.
Another great feature of this machine is the built-in burr grinder. This feature is perfect for those who are new to the field because it avoids having to purchase a separate grinder. The grinder is an stainless steel conical unit with 18 settings from "coarse" to "fine."
The grinder isn't the same as a stand-alone device, but it's a good beginning and will get you well on your way to brewing quality espresso shots. It's easy to clean and you can also pause it while grinding this will help you avoid the creation of a mountain of grounds that will spill all over your portafilter on its way to making tamps.
It's a beautiful and practical machine that allows you to experience the excitement of becoming a barista from home. It's a great option for anyone who wants to be able to look back at the fond memories of pouring microfoam into their morning cup of joe or locking a portafilter into the grouphead, and tamping with precision. For those who just want convenience, a bean to cup machine might be a better option.
Water
It is a challenge to master. The trick is finding the right balance. Too much caffeine can cause mineral deposits to coffeee machines form in your machine. But too little can result in an espresso cup that is weaker.
The perfect espresso water has the lowest alkalinity and hardness level. This is best achieved by using a water filter system which removes chlorine and puts an amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will result in an ideal balance of alkalinity and hardness and avoid the necessity of decalcifying your machine.
Using a high quality filtered water is crucial to your machine's long term health as well as the flavor of the coffee it makes. Based on the usage and the hardness of your machine, you should use descaling products on a regular schedule. These products are available in powder, liquid and tab forms and can be found at most hardware stores.
The Breville Barista Express, a premium espresso machine for home use designed to bring the cafe experience to your home. It comes with more advanced features than other espresso machines that are geared towards coffee lovers who want to perfect their technique and improve their craft. The thermocoil heating system that comes with a built-in PID controller centered on the active heated group head makes it easy to regulate your brewing temperature. This is a huge advantage over other entry-level models that require long periods of "temperature-surfing" to achieve consistent espresso shots.
