What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines around the globe. It is composed of three main components. The bottom holds the water and the middle is a filter-basket with a metal filter.
This machine was a big hit and helped popularize home barista espresso. Its features include a low-pressure pre-infusion as well as the 2.2L boiler and brewing pressure of 9 bar.
Pressure
If you're a coffee lover, you will know that the pressure of your espresso machine is a key factor in the quality of your drink. The pressure of your machine is essential to brewing great coffee, whether you want a thick layer or the perfect balance of flavor and acidity.
BARs (Barometric Pressure) refer to the amount of force exerted on the grounds of your coffee when your espresso machine is pumping out its high-pressure water. Your espresso machine is pushing hot water through the coffee grounds at a rate nine times Earth's current atmosphere pressure.
The pressure of your machine is vital because it allows water to pass through coffee grounds at a proper speed and intensity. If the pressure is too low the flavors and oils dissolved won't be properly extracted. On the other side, if the pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end with a weak, diluted cup of espresso.
You can control the pressure of your espresso maker by adjusting the screw that is attached to the espresso pump. Commercial machines as well as some high-end home appliances have pumps with rotary that can be adjusted. For the cheaper home machines that have the vibrating pump, altering the pressure isn't possible without involving DIY hacks. Companies such as Cafflano however, are developing technology that uses Pascal's Principle in order to maintain pressure in the portafilter during the fermentation process.
Temperature
The temperature is one of the most critical factors for the perfect espresso shot. If the water is too hot, it may scorch the coffee grounds and create an over-extracted bitter coffee. The ideal extraction temperature is around 200 degrees Fahrenheit, which allows the water to extract all the desirable coffee flavors without scorching the grounds or over-extracting.
The top espresso machines include a thermoblock that heats the water and keeps it at a constant temperature throughout the whole extraction process. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts as necessary making sure that the brew head remains at a perfect temperature to extract the coffee.
The majority of coffee drinkers are aware that the temperature of your espresso maker is an essential element in brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To achieve this, you need an espresso machine with a top thermoblock, thermocoil and a boiler that is appropriately sized.
It is also essential to heat your machine or portafilter before making espresso. Beginners often make the mistake of not preheating their machine. You should always read your espresso machine's manual before you try it for the very first time.
Grind
A barista machine should give you a variety of grind settings, so that you can have the most control over your final cup of espresso. Some machines have an analog gauge which looks cool and aids you improve your brewing skills. The ideal goal is to get around nine bars of pressure, and keep that throughout the brew cycle. Although small espresso machine this machine can't reach the mark, it's pretty close and will serve you well.
Another nice touch on this machine is a built-in burr grinder. This feature is perfect for novices because it doesn't mean the need for a separate grinder. The grinder is an stainless steel conical unit with 18 settings from "coarse" to "fine."
It's not as efficient as a stand-alone device, but it can get you started on the right track to making excellent espresso shots. It's easy-to-clean and you can stop the grinder in the process of grinding to avoid accumulating an overwhelming amount of ground on your portafilter while it's being put through the tamper.
This gorgeous and practical machine will let you feel like a barista from your home. This is a great option for those who wish to relive the thrill of pouring microfoam into their morning cup of coffee, locking the portafilter into the head of the grouphead and then tamping with precision. A bean-to-cup machine is a great choice for those looking for a simple and convenient solution.
Water
Water is a tricky thing to master. It's important to find the appropriate balance. Too much caffeine can cause mineral deposits to develop in your machine. But too little will result in a weaker cup of espresso.
The ideal espresso water is soft and high in alkalinity. This can be achieved with a water filter system that eliminates chlorine and brings back in a small amount of total dissolving solids (TDS) to add some calcium and magnesium to the mix. This will ensure an optimal balance between hardness and acidity and will also prevent the necessity of decalcifying.
It is vital to use filtered water of good quality to ensure the health and taste of your machine. Descaling products should be used on a regular basis depending on the strength and use of your machine. These products are available in liquid, powder or tab in a variety of hardware stores.
The Breville Barista Express is a top-of-the-line, luxurious home espresso machine that was designed to bring the cafe experience into the home. It has more advanced features than other beginner machines, and is targeted at those who are looking to refine their technique and perfect the craft. The thermocoil heating mechanism with a built-in PID controller centered on the actively heated group head makes it simple to control your brewing temperature. This is a huge advantage over other entry-level models which require you to spend a lot of time "temperature-surfing" to get a consistent espresso shot.
