What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines on the planet. It is composed of three main parts. The bottom holds the water while the middle is a filter-basket with a filter made of metal.
This machine was a huge success and helped to popularize the prosumer (home barista) espresso market. Its features include a low-pressure pre-infusion, a 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso maker is a crucial factor in how your drinks are made. It doesn't matter if you're seeking a thick layer of crema, or the perfect balance of flavor and acidity, the pressure of your espresso maker is the key to brewing good espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of the coffee while delivering high-pressure water. 9 BARs mean that your espresso machine is forcing heated water through the ground coffee at a the rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is essential because it allows water to move through coffee grounds at the correct speed and intensity. If the pressure is too low, the dissolved oils and flavors aren't extracted properly. On the other however, if the pressure is too high, the water will be pushed through the coffee grounds too quickly, and you'll end up with an over-extracted, weak cup of espresso.
The pressure of your espresso machine can be adjusted by turning the screw found on the espresso pump. Commercial machines and a few high-end home machines have rotating pumps that can be adjusted. For home-based machines that have a vibrating motor, it's impossible to adjust the pressure with DIY hacks. However, companies such as Cafflano are working on technology that utilizes Pascal's Principle to create maintained pressure inside the portafilter during the fermentation process.
Temperature
Temperature is among the most important factors in a perfect espresso shot. If the water is too hot, it could scorch the coffee grounds and produce an over-extracted bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit which allows the water to extract all of the desirable coffee flavors without scalding the grounds or over-extracting.
The best espresso machines feature the thermoblock, or thermocoil which heats the water and maintains it at an even temperature throughout the extraction cycle. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system which constantly checks the temperature of the water and adjusts as necessary, ensuring that the brewhead stays at the perfect temperature for extraction.
The majority of coffee drinkers know that the temperature of the espresso machine is essential to making a great cup of coffee. The ideal temperature for brewing espresso is between 190 to 196 degrees Fahrenheit. To achieve this, your espresso machine should have a high-quality thermoblock or thermocoil, and the boiler should be of the right size.
Additionally, it is important to pre-heat your machine, portafilter, and cup prior to making espresso. Espresso makers who are beginners often make the mistake of not preheating their equipment. It is recommended to read your espresso machine's manual prior to attempting to start using it for the first time.
Grind
A barista espresso machine must provide a variety grind settings to give you the most control over the final cup of coffee. Some machines come with an analog gauge that looks cool and can help you develop your brewing capabilities. In the ideal scenario, you'll want to hit about nine bars of pressure and keep that throughout the brew cycle. Although this machine isn't hitting this mark, it's close enough and will serve you well.
Another excellent feature of this machine is a built-in burr grinder. This feature is great for those who are new to the field because it avoids having to buy a separate grinder. The stainless steel conical grinder comes with 18 settings that range from "coarse to fine."
This grinder isn't the same as a stand-alone unit, but it's a solid start and will get you on the right espresso machine with frother track to making quality espresso shots. It's easy to clean and you'll be able to stop the grinder during the process of grinding to avoid accumulating an overwhelming amount of ground on your portafilter as it's being tamped.
This is a beautiful and practical machine that allows you to feel the excitement of becoming a barista from home. This is a great choice for those who wish to recall the thrill of pouring microfoam in their morning cup of coffee by locking the portafilter to the head of the grouphead and tamping the coffee with precision. A bean-to-cup machine is an excellent choice for those who are looking for convenience.
Water
Water can be a challenging thing to master. It's important to find the optimal balance. Too much can cause mineral deposits to build up in your machine. But too little can result in an espresso cup that is weaker.
The ideal espresso water is soft and high in alkalinity. It is recommended to use a filter that does not contain chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will give you an ideal balance between hardness and acidity and will also prevent the necessity of decalcifying.
It is essential to make sure you use water that has been filtered to a excellent quality for the health and flavor of your machine. Descaling products must be used on a regular basis according to the hardness and use of your machine. They are available in powder, liquid and tab forms and are available in many hardware stores.
The Breville Barista Express, a top-of-the-line home espresso machine designed to bring the cafe experience into your home. It comes with more advanced features than other espresso machines that are designed for coffee enthusiasts who wish to refine their technique and improve their craft. The thermocoil heater, with an integrated PID controller situated on the group head that is continuously heated which makes it simple to regulate your brewing temperature. This is a significant advantage over other entry-level models that require you to spend longer "temperature surfing" to get an espresso shot that is consistent.
