What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complicated coffee machines in the world. It is comprised of three primary components. The bottom holds the water while the middle is a filter-basket with a filter made of metal.
This machine was a big success and was instrumental in bringing home barista espresso. Features include a 2.2L steam boiler, low pressure pre-infusion and 9 bar pressure for brewing.
Pressure
If you are a coffee enthusiast, you will know that the pressure of your espresso machine is a crucial 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) is the force your espresso machine exerts upon the grounds of your coffee while delivering high-pressure water. 9 BARs mean that your espresso machine is forcing heated water through the coffee grounds at the rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is important because it allows the water to pass through the coffee grounds at the right speed and intensity. If the pressure is low the oils and flavors will not be extracted properly. On the other contrary, if pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end up 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 some of the top-end home machines use the rotary pumps, which are adjustable. For the cheaper home machines that use an oscillating pump, changing the pressure is difficult without engaging in DIY hacks. Companies such as Cafflano however, are developing technology that utilizes Pascal's Principle in order to maintain pressure in the portafilter during the fermentation process.
Temperature
The temperature is one of the most important factors in brewing an excellent espresso shot. The water that is too hot can scorch the coffee grounds, resulting in a bitter brew. The ideal temperature for extraction is around 200 degrees Fahrenheit, which allows the water to extract all the desired flavors of coffee without scorching the grounds, or over-extracting.
The best espresso machines include a thermoblock, or thermocoil that heats water and maintains it at an even temperature throughout the extraction. The Breville Barista Express has a PID system (Proportional Integral Derived) which constantly monitors and adjusts the temperature of the water. This ensures that the brewhead remains at the ideal temperature for extraction.
The majority of coffee drinkers know that the temperature of an espresso machine is crucial to a good cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190-196. To get this temperature, you need an espresso machine with a top thermoblock, thermocoil and a boiler that is correctly sized.
It is also essential to pre-heat your machine, portafilter, and cup prior to making a shot. Espresso makers who are beginners often make the mistake of not heating their machine prior to making a shot. This is the reason why you should always go through the instruction manual prior to making espresso for the first time.
Grind
A barista espresso machine should provide a variety grind settings for you to have the most control over the final cup of coffee. Some machines have an analog gauge that looks cool and can help you improve your brewing abilities. You should aim to maintain the pressure at nine bars throughout the brewing cycle. While this machine doesn't hit this mark, it's close enough and will serve you well.
A built-in burr mill is a good feature. This is a fantastic feature for people who are new to espresso since it eliminates the need to pay for an additional burr grinder. The grinder is a conical stainless steel unit with 18 settings, ranging from "coarse" to "fine."
The grinder isn't as powerful as a standalone unit, but it's a solid start and will put you on the path to creating quality espresso shots. It's easy to clean and you can stop the grinder in the grinding process to prevent accumulating a large amount of grounds on your portafilter while it is being tamped.
This is a beautiful here and practical machine that lets you to feel the excitement of becoming a barista from home. It's a great option for those who wish 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. A bean-to-cup machine is a great option for those who want convenience.
Water
Water is a challenging thing to master. Finding the right balance is crucial. Too much caffeine can cause mineral deposits to build up in your machine, while too small and you'll struggle to make a full cup of espresso.
The perfect water for espresso is low in hardness and high in alkalinity. This is best accomplished by using an effective water filtering system that bypasses all chlorine and adds back in a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will result in an ideal balance of alkalinity and hardness and prevent the necessity of decalcifying your equipment.
Using a high-quality filter water is essential for your machine's long-term 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 a descaling product regularly. These products are available as tab, liquid, or powder form at a majority of hardware stores.
The Breville Barista Express, a luxurious, high-end espresso machine for your home, is designed to bring the café experience to your home. It comes with more advanced features than other machines for beginners designed for coffee lovers who wish to refine their technique and improve their craft. The thermocoil heating system with integrated PID controller, centered on the group head makes it simple to control your brewing temperature. This is a significant benefit over other models that require you to spend longer "temperature surfing" to achieve an even shot of espresso.
