What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines around the world. It is comprised of three primary components. The bottom holds the water while the middle is a filtration basin with a filter made of metal.
This machine was a huge success and helped to 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 are an avid coffee drinker, then you'll realize that the pressure of your machine is a major factor in the quality of your coffee. The pressure of your machine is vital in brewing excellent coffee whether you're looking for a thick layer or a perfect balance of flavor and acidity.
BARs (Barometric Pressure) refer to the force applied to the coffee grounds when your espresso machine is delivering its high-pressure water. The espresso machine is pushing heated water through the coffee grounds at a rate nine times the current atmospheric pressure.
The pressure of your machine is important because it allows water to pass through the coffee grounds at the proper speed and intensity. If the pressure is too low, the oils and flavors aren't extracted properly. On the other contrary, if pressure is too high the water will be forced through the coffee grounds too quickly and you'll end up 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 and high-end home machines come with rotary pumps with adjustable pressure. For home machines that are less expensive that use a vibrating motor, it's impossible to alter the pressure with DIY hacks. However, companies like Cafflano are developing technology that employs Pascal's Principle to maintain pressure in the portafilter during the beer making process.
Temperature
Temperature is one of the most important factors in the perfect espresso shot. If the water is too hot, it can cause the coffee grounds to burn and create a bitter brew. 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 best espresso machines feature the thermoblock, also known as a thermocoil which heats the water and maintains it at an unchanging temperature throughout the extraction cycle. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts if needed so that the brew head remains at a perfect temperature to extract the coffee.
Most coffee lovers are aware that the temperature of an espresso machine is crucial to a good cup of coffee. The ideal temperature for espresso is between between 190-196. To achieve this, you need a machine with a good thermoblock, thermocoil and boiler that is correctly sized.
Additionally, it is important to pre-heat your portafilter, espresso machine, and cup prior to making an espresso. Inability to heat your equipment is one of the most frequent mistakes that can be made by novice espresso makers. It is recommended to read your espresso machine's manual before you use it for the first time.
Grind
A barista machine should offer you a range retro espresso machine of grind settings so you can have the most control over your final cup of espresso. Some machines come with an analog pressure gauge, which looks cool and can help you gain knowledge about the brewing process. Ideally, you want to achieve around nine bars of pressure and maintain that throughout the brewing cycle. While this machine does not hit the mark, it's quite close and will serve you well.
A built-in burr mill is another great feature. This feature is great for beginners since it eliminates the need to purchase a separate grinder. The grinder is a conical stainless steel unit with 18 settings from "coarse" to "fine."
The grinder isn't the same as a standalone unit, but it's an excellent start and will have you on the right track to making quality espresso shots. It's easy to clean, and you can stop it while grinding, which helps you avoid creating a mountain of ground that will fall onto your portafilter on its way to tamping.
This gorgeous and practical machine will let you be a barista at your home. It's a great choice for those who want to be able to revisit the memories of pouring the microfoam into your morning cup of coffee, locking a portafilter into the grouphead, and tamping with precision. For those who just want convenience, a bean-to- cup machine might be a better option.
Water
Water can be a tricky thing to master. Finding the right balance is crucial. Too much caffeine can cause mineral deposits to build up in your machine. But too little can result in an espresso that is weaker.
The best espresso water has a low hardness and alkalinity level. It is recommended to use a filter which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will give you the right balance between acidity and hardness and also avoid the need to decalcify.
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. A descaling product should be used on a regular basis depending on the hardness and usage of your machine. They are available in tab, liquid, or powder in a variety of hardware stores.
The Breville Barista Express is a premium, high-end espresso machine for home use that is designed to bring the cafe experience into the home. It comes with more advanced features than other beginner machines which are targeted at coffee enthusiasts who wish to perfect their technique and perfect their craft. The thermocoil heating technology with an integrated PID controller mounted around the heated group head makes it simple to regulate your brewing temperature. This is a significant benefit over other models which require more time "temperature surfing" to achieve an even shot of espresso.
