What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complex coffee machines around the world. It is comprised of three major parts. The bottom holds the water and the middle is the filter-basket.
This machine was a huge success and helped to popularize the prosumer (home barista) espresso market. It features a 2.2L steam boiler, a low pressure pre-infusion and 9 bar brewing pressure.
Pressure
If you're serious about coffee then you're aware that the pressure of your espresso machine is a crucial factor in how well your drinks are made. If you're looking for a thick layer of crema or perfect balance of flavor and acidity, the pressure of your espresso machine is essential to making great espresso.
BARs (Barometric Pressure) refer to the force that is imposed on the grounds of your coffee when your espresso machine is pumping out its high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is vital because it allows water to pass through coffee grounds at the proper speed and intensity. If the pressure is too low, the flavors and oils dissolved won't be properly extracted. On the other however, if the pressure is too high, the water will be pushed through the coffee grounds too fast and you'll end with a weak and over-extracted cup of espresso.
You can regulate the pressure of your espresso maker by adjusting the screw of the espresso maker. Commercial machines and top-end home machines feature rotary pumps with adjustable pressure. For the cheaper home machines, which use a vibrating motor, it is not possible to adjust the pressure with DIY hacks. Companies such as Cafflano however, are working on technology that utilizes Pascal's Principle to ensure pressure in the portafilter during the fermentation process.
Temperature
Temperature is one of the most important factors in a great espresso shot. A hot water can burn the grounds of the coffee, resulting in a bitter espresso. The ideal extraction temperature is 200 degrees Fahrenheit which allows the water to extract all of the desired flavors of coffee without scorching the grounds or over-extracting.
The top espresso machines feature a thermoblock, or thermocoil which heats the water and keeps it at a steady temperature throughout the whole extraction cycle. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system that continuously monitors the temperature of water and adjusts according to the need to ensure that the brewhead remains at a perfect temperature for extraction.
Most coffee lovers are aware that the temperature of the espresso maker is crucial to brewing a perfect cup of coffee. The ideal temperature for espresso is between 190 and 196. To achieve this, your espresso machine should have a high-quality thermoblock or thermocoil, and the boiler should be sized appropriately.
It is also important to heat up your machine as well as the portafilter and cup prior to making the travel espresso maker espresso. Beginner espresso makers often make the mistake of not preheating their equipment. This is why it is important to always read the instruction manual before using your espresso maker for the first time.
Grind
A barista machine must give you a range of grind settings, so that you have the maximum control over your final cup of espresso. Some machines come with an analog gauge that is cool and helps you to improve your brewing skills. In the ideal scenario, you'll want to reach around nine bars of pressure, and keep that throughout the brewing cycle. Although this machine can't reach the desired pressure, it's pretty close and will serve you well.
A built-in burr mill is a great feature. This feature is ideal for novices because it doesn't mean having to purchase an additional grinder. The grinder is a stainless steel conical device with 18 settings from "coarse" to "fine."
The grinder isn't the same as a stand-alone device, however, it's a decent start and will have you on the path to making high-quality espresso shots. It's easy-to-clean and you can stop the grinder in the grinding process to prevent accumulating a large amount of ground in your portafilter when it's being tamped.
It's a beautiful and functional machine that allows you to experience the excitement of being a barista home. This is an excellent choice for anyone who would like to relive the thrill of pouring microfoam in their morning coffee by locking the portafilter to the grouphead's head and tamping the coffee with precision. For those who simply want convenience, a bean-to- cup machine could be a better fit.
Water
Water can be a challenging thing to master. It's important to find the optimal balance. Too much and it can cause mineral deposits in the machine, but too little and you'll struggle get a good cup of espresso.
The ideal espresso water has a low hardness and alkalinity level. This is best achieved by using a water filter system that removes chlorine and puts back in a small amount of total dissolving solids (TDS) to add calcium and magnesium to the mix. This will result in a balanced balance of alkalinity as well as hardness. It will also help avoid the need to decalcify your machine.
Using a high quality filtered water is crucial to your machine's longevity health as well as the taste of the coffee it makes. Descaling products should be regularly used according to the hardness and usage of your machine. The products are available in liquid, powder and tab forms and are available at many hardware stores.
The Breville Barista Express, a luxurious, high-end espresso machine for your home, is designed to bring the cafe experience into your home. It comes with more advanced features when compared to other beginner machines, and is geared towards those who are looking to refine their technique and perfect their art of coffee. The thermocoil heating system that comes with an integrated PID controller mounted on the active heated group head makes it simple to control your brewing temperature. This is an enormous benefit over other models which require more time "temperature surfing" in order to pull a consistent shot of espresso.
