What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines available. It has three main parts. The bottom holds the water, and the middle part is a filter-basket with a metal filter.
This machine was a huge hit and helped popularize the prosumer (home barista) espresso market. Its features include a low pressure pre-infusion and a 2.2L boiler and brewing pressure of 9 bar.
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 are made. It doesn't matter if you're seeking a thick layer of crema or the right balance of acidity and flavor the pressure of your espresso machine is the key to brewing great espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts on the grounds of your coffee while delivering high-pressure water. 9 BARs means that your espresso machine is forcing heated water through the ground coffee at a rate of nine times the Earth's current atmospheric pressure.
The pressure of your espresso machine is vital because it allows water to move through the grounds of your coffee with the right speed and in the right amount. If the pressure isn't sufficient the oils and flavors will not be extracted properly. If the pressure is too low the dissolved flavors and oils won't be extracted properly.
The pressure of your espresso machine can be controlled by adjusting the screw on the espresso pump. Commercial machines and top-end home machines have rotary pumps with adjustable pressure. For the less expensive home machines that utilize a vibration motor, it is impossible to alter the pressure without DIY hacks. However, companies such as Cafflano are developing technology that uses Pascal's Principle to create maintained pressure inside the portafilter during the brewing process.
Temperature
The temperature is among the most critical factors for the perfect espresso shot. If the water is too hot, it can ignite the coffee grounds and result in an over-extracted bitter espresso. The ideal extraction temperature is about 200 degrees Fahrenheit, which allows the water to extract all the coffee's desirable flavors without scorching the grounds, or over-extracting.
The top espresso machines come with the thermoblock, or thermocoil which heats the water and keeps it at a constant temperature throughout the extraction cycle. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system that constantly monitors the water temperature and adjusts as necessary so that the brew head stays at the ideal temperature to extract the coffee.
The majority of coffee drinkers are aware that the temperature of your espresso machine is a key factor to brewing a high-quality cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, you require an espresso maker with a reliable thermoblock, thermocoil and a boiler that is appropriately sized.
In addition, it is essential to heat your espresso maker, portafilter and cup prior to taking espresso. A failure to warm your espresso maker is among the most frequent errors committed by novice espresso makers. It is advisable to read your espresso machine's manual prior to attempting to start using it for the first time.
Grind
A barista machine should offer you a range of grind settings so that you can have the greatest control over the final cup of espresso. Some machines come with an analog pressure gauge, that is stylish and can help you gain knowledge about your brewing abilities. The ideal espresso coffee machines goal is to hit about nine bars of pressure and keep it throughout the brewing process. While this machine doesn't hit the desired pressure, it's pretty close and will serve you well.
A built-in grinder is another nice touch. This is a great feature for newbies to espresso as it will not require you to shell out money for a separate burr grinder. The stainless steel conical grinder has 18 settings, which range from "coarse to fine."
This grinder isn't as good as a stand-alone unit, but it will get you going in the right direction to making excellent espresso shots. It's easy to clean and you'll be able to pause the grinder during the process of grinding to avoid accumulating a huge amount of ground on your portafilter while it's being put through the tamper.
This gorgeous and useful machine will allow you to be a barista at your home. It's an excellent choice for those who wish to to look back at the memories of pouring the microfoam into their morning cup of joe or locking a portafilter into the grouphead, and tamping with precision. A bean to cup machine is a good option for those looking for a simple and convenient solution.
Water
Water can be a difficult thing to master. It's important to find the right balance. Too much caffeine can cause mineral deposits to form in your machine. However, too little will result in less of an espresso.
The perfect water for espresso is soft and high in alkalinity. This can be achieved with a water filter system which does away with chlorine and then adds back in a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will result in a good balance of hardness and alkalinity and will reduce the necessity of decalcifying your equipment.
Using a high quality filtered water is crucial to your machine's longevity health and the flavor of the coffee it produces. Based on the usage and hardness of your machine, you should use a descaling product on a regular basis. These products come in powder, liquid and tab forms and can be found in all hardware stores.
The Breville Barista Express is a premium, high-end home espresso machine that was designed to bring the cafe experience inside your home. It has more advanced features compared to other beginner machines, and is geared towards those who are looking to refine their technique and master the craft. The thermocoil heating system with an integrated PID controller centered on the group head that is continuously heated, makes it easy to regulate your brewing temperatures. This is a significant advantage over competing entry-level models that require longer "temperature surfing" to achieve an espresso shot that is consistent.
