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 made up of three main components The bottom houses the water and the middle is the filterbasket The machine was a huge hit and helped popularize home barista espresso Its features include a low pressure preinfusion as well as an 22L boiler and brewing pressure of 9 bar Pressure If youre serious about coffee then you know the pressure of your espresso maker is an essential factor in how your drinks taste The pressure of your machine is vital to brewing great coffee whether youre looking for a dense layer or a perfect balance of flavor and acidity BARs Barometric pressure is the force your espresso machine exerts on coffee grounds while delivering highpressure water 9 BARs means that the espresso machine is pushing heated water through the ground coffee at a rate of nine times the Earths current atmospheric pressure The pressure of your machine is essential because it allows the water to pass through coffee grounds at a proper speed and intensity If the pressure isnt high enough the flavors and oils will not be extracted correctly If the pressure is too low the dissolved oils and flavors will not be extracted properly The pressure of your espresso machine can be controlled by adjusting the screw located on the espresso pump Commercial machines and a few highend home appliances use pumps with rotary that can be adjusted For the cheaper home machines which use a vibrating motor it is not possible to alter the pressure without hacks However companies like Cafflano are working on technology that uses Pascals Principle to create maintained pressure inside the portafilter during the making process Temperature Temperature is one of the most important factors in the making of a good espresso shot Hot water can cause burning of the grounds of the coffee leading to bitter brew The optimal temperature for extraction is 200 degrees Fahrenheit This allows the water to extract all desired coffee flavors without burning the grounds or causing excessive extraction The best espresso machines have a thermoblock or thermocoil that warms the water and keeps it at a stable temperature throughout the whole extraction cycle The Breville Barista Express for instance comes with PID Proportional Integral Derivative system that constantly monitors the water temperature and adjusts according to the need ensuring that the brewhead remains at a perfect temperature to extract the coffee Many coffee drinkers are aware that the temperature of the espresso machine is vital to brewing a great cup of coffee The ideal temperature for espresso is between Fahrenheit between 190 and 196 In order to get this temperature your machine should have a highquality thermoblock or thermocoil and the boiler must be of the right size Additionally it is essential to heat your portafilter espresso machine and cup prior to making the shot The failure to preheat is among the most common mistakes made by novice espresso makers This is why you should always study the instruction manual before using your espresso machine for the first time Grind A barista machine must give you a variety of grind settings so that you can have the most control over the final cup of espresso Some machines include an analog pressure gauge which looks cool and can help you learn about your brewing techniques Ideally you should reach around nine bars of pressure and keep that throughout the brew cycle This machine is getting close to hitting that target Another wonderful feature of this machine is a builtin burr grinder This feature is great for beginners because it eliminates having to purchase a separate grinder The grinder is a stainless steel conical device with 18 settings from coarse to fine Its not as efficient as a standalone unit but it will get you started on the right track to make great espresso shots Its easy to clean and you can stop the grinder during the grinding process to avoid creating a mountainous amount of ground on your portafilter as it is being crushed Its a beautiful and functional machine that allows you to feel the excitement of being a barista at home espresso coffee machines s a great choice for those who want to be able to look back on the moments of pouring microfoam into their morning cup of joe or locking a portafilter into the grouphead and tamping with precision For those who simply want convenience a beanto cup machine might be the better choice Water Water is a tricky thing to master Its important to find the proper balance Too much can cause mineral deposits to form in your machine But too little can result in less of an espresso The ideal espresso water has low alkalinity and hardness level This is best achieved by using a water filter system which does away with chlorine and then adds back a small amount of total dissolved solids TDS to add calcium and magnesium to the mix This will result in a balanced balance of alkalinity as well as hardness It will also prevent the necessity of decalcifying your equipment It is essential to use filtered water of excellent quality for the health and taste of your machine Depending on the use and the hardness of your machine you should use descaling products regularly The products are available in tab liquid or powder form at most hardware stores The Breville Barista Express a luxury highend home espresso machine is designed to bring the café experience into your home It is equipped with more advanced features when
