What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines on the planet. It is made up of three main parts. The bottom is where the water goes and the middle is the filter-basket.
This machine was a huge success and helped popularize the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, low pressure pre-infusion and 9 bar pressure for brewing.
Pressure
If you're a coffee enthusiast, you will know that the pressure of your machine is a key element in the quality of your drink. It doesn't matter if you're seeking an even layer of crema or right balance of flavor and acidity, the pressure of your espresso maker is the most important factor in brewing good espresso.
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. 9 BARs means that the espresso machine is pushing heated water through the ground coffee at a a rate of nine times the current atmospheric pressure.
The pressure of your machine is vital because it allows water to pass through the coffee grounds at the right speed and intensity. If the pressure is too low the flavors and oils dissolved won't be properly extracted. On the other contrary, if pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end 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 top-end home machines have rotating pumps that can be adjusted in pressure. For home machines that are less expensive that have a vibrating motor, it's not possible to alter the pressure with DIY hacks. Companies such as Cafflano however, are developing technology which uses Pascal's Principle in order to maintain the pressure inside the portafilter throughout the fermentation process.
Temperature
Temperature is one of the most important elements in a perfect espresso shot. Hot water can cause burning of the grounds of the coffee, resulting in a bitter brew. The ideal temperature for extraction is about 200 degrees Fahrenheit which allows the water to extract all the desirable coffee flavors without scorching the grounds, or over-extracting.
The best espresso machines include thermoblocks, also known as thermocoils, which heats water and keeps it at a constant temperature throughout the extraction process. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that constantly checks the temperature of the water and adjusts as necessary so that the brew head stays at a perfect temperature for extraction.
Many coffee drinkers are aware that the temperature of the espresso maker is crucial to a good cup of coffee. The ideal temperature for espresso is between between 190-196. To attain this, you will require an espresso maker with a reliable thermoblock, thermocoil and a boiler that is sized correctly.
Additionally, it is crucial to warm your espresso maker, portafilter and cup prior to taking an espresso. Inability to heat your equipment is one of the most common mistakes that can be made by novice espresso makers. This is the reason you should always review the instruction manual before making espresso for the first time.
Grind
A barista machine must give you a range of grind settings so that you have the maximum control over the final cup of espresso. Some machines include an analog gauge that looks cool and can help you improve your brewing skills. The ideal goal is to get around nine bars of pressure and maintain that throughout the brewing cycle. This machine is getting close to reaching that goal.
A built-in grinder is another great feature. This feature is perfect for beginners because it eliminates having to purchase an additional grinder. The grinder is an stainless steel conical unit with 18 settings, ranging from "coarse" to "fine."
This grinder isn't as good as a stand-alone unit, but it can get you more info to the right path to making excellent espresso shots. It's easy to clean and you can even pause it while grinding and avoid making a mountain of ground that can spill all over your portafilter on its way to tamping.
This is a stunning and functional machine that will allow you to experience the thrill of being a barista at home. It's an excellent choice for anyone who wants to to look back at the fond memories of pouring microfoam into your morning cup of coffee by locking a portafilter to the grouphead, and tamping with precision. If you're looking for convenience, a bean-to- cup machine might be a better choice.
Water
Water can be a difficult thing to master. Finding the right balance is essential. Too much caffeine can cause mineral deposits to form in your machine. But too little can result in less of an espresso.
The perfect water for espresso is low in hardness and high in alkalinity. It is best to use a water purifier which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will ensure the right balance between acidity and hardness and also avoid the necessity of decalcifying.
It is important to use filtered water of good quality to ensure the health and taste of your machine. A descaling product should be used on a regular basis, depending on the hardness and use of your machine. The products are available in tab, liquid or powder form at most hardware stores.
The Breville Barista Express, a premium espresso machine for home use, is designed to bring the cafe experience into your home. It offers more advanced features than other beginner machines that are designed for those who are looking to refine their technique and improve their craft. The thermocoil heater that has an integrated PID controller placed on the group head that is heated continuously, makes it easy to regulate your brewing temperature. This is a major advantage over other models at the entry level that require lots of time "temperature-surfing" to ensure a consistent espresso shot.
