What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines around the globe. It is comprised of three main components. The bottom holds the water while the middle is a filter-basket with a filter made of metal.
This machine was a huge hit and helped popularize the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, 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 an essential factor in how your drinks taste. The pressure of your machine is essential in brewing excellent coffee whether you're seeking a thick layer or the perfect balance of acidity and flavor.
BARs (Barometric Pressure) refer to the amount of force applied to the coffee grounds when your espresso machine is delivering its high-pressure water. 9 BARs means that your espresso machine is pushing 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 vital because it allows water to pass through coffee grounds at the right speed and intensity. If the pressure isn't sufficient, the oils and flavors won't be extracted properly. If the pressure is too low the dissolved flavors and oils will not be extracted correctly.
You can control the pressure of your espresso maker by adjusting the screw on the espresso maker. Commercial machines as well as some high-end home appliances have rotating pumps that can be adjusted. For home machines that are less expensive that have a vibrating motor, it is impossible to adjust the pressure without hacks. Companies such as Cafflano however, are working on technology that is based on Pascal's Principle in order to maintain pressure in the portafilter during the beer making process.
Temperature
The temperature is among the most crucial factors to a great espresso shot. If the water is too hot, it may heat the coffee grounds and create a bitter coffee. The ideal extraction temperature is around 200 degrees Fahrenheit, which allows the water to extract all the coffee's desirable flavors without burning the grounds or over-extracting.
The top espresso machines include a thermoblock or thermocoil that is used to heat the water and keep it at a stable temperature throughout the whole extraction cycle. The Breville Barista Express, for example, has PID (Proportional Integral Derivative) system that constantly monitors the temperature of the water and adjusts if needed so that the brew head remains at the right temperature to extract the coffee.
Many coffee drinkers know that the temperature of your espresso maker is an important factor in the production of a good cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196. To achieve this, your machine must have a quality thermoblock or thermocoil, and the boiler should be of the right size.
It is also essential to pre-heat your machine, portafilter, and cup prior to making shots. Espresso makers who are beginners often make the mistake of not preheating their equipment. This is why you should always go through the instruction manual prior to using your espresso maker for the first time.
Grind
A barista espresso machine should also provide a variety grind settings to give you the most control over your final cup of coffee. Some machines have an analog pressure gauge which is cool and can help you gain knowledge about your brewing techniques. The goal is to maintain a pressure of nine bars throughout the process of brewing. This machine is close to the goal.
A built-in grinder is another great feature. This is a wonderful 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 that has 18 settings from "coarse" to "fine."
This grinder isn't as good as a stand-alone unit, but it will get you to the right path to creating great espresso shots. It's easy-to-clean and you can stop the grinder in the grinding process to avoid creating a mountainous amount of grounds in your portafilter when it is being put through the tamper.
This gorgeous and useful machine will allow you to be a barista at your home. This is a great choice for anyone who wants to relive the excitement of pouring microfoam in their morning coffee and locking the portafilter into the grouphead's head and then tamping with precision. A bean-to-cup machine is a great choice for those who want convenience.
Water
Water can be a challenging thing to master. The trick is finding the optimal balance. If you're using too much, it could result in mineral deposits on the machine, but too little and you'll struggle enjoy a satisfying cup of espresso.
The perfect water for espresso is low in hardness and high in alkalinity. It is best to use a water filter that bypasses chlorine and adds a small amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will provide the right balance between acidity and hardness and will also prevent the need to decalcify.
A high-quality, filtered water is crucial to your machine's overall health as well as the taste of the coffee it makes. Depending on the use and hardness of your machine you should make use of descaling products regularly. The products are available in tab, liquid or powder form at a majority of hardware stores.
The Breville Barista Express is a premium, high-end espresso machine for home use that is designed to bring the experience best espresso maker of a cafe into your home. It has more advanced features than other beginner machines that are geared towards those who are looking to refine their technique and perfect their craft. The thermocoil heater, with an integrated PID controller centered on the group head which is constantly heated allows you to control your brewing temperature. This is an enormous advantage over the other models that require longer "temperature surfing" to get a consistent shot of espresso.
