What to Look For in a Professional Espresso Machine You'll need a machine with the capability to regulate the pre-infusion. This is essential for developing flavor. PID temperature control is also an option that coffee experts are looking for in a professional espresso machine. If you're planning to hire baristas with little experience, you'll need a machine that is easy to train. This is important when you are planning to operate an open-air coffee shop. Easy of Use This professional espresso machine, as you could have guessed by its name is designed to be simple to operate and maintain. It has an integrated grinder that automatically grinds coffee beans into the portafilter. It also comes with a digital temperature control to ensure optimal extraction as well as the manual steam wand that can create microfoam. It also comes with test strips that help you measure the water's hardness and an AquaClean filter system that helps reduce scale. For baristas who are at home this machine offers a great balance between manual and automatic operation, allowing you to feel like a pro pulling a shot of espresso (though there is a bit of an learning curve). The built-in grinder lets you to play around with the grind size to fine-tune your process. Additionally the manual steam wand is a straightforward method to create frothy lattes and cappuccino milk. It also comes with a dishwasher-safe, removable milk hopper that makes cleaning up after each use simple and simple. While this model is intended for use at home however, it has some advanced features that set it apart from professional espresso machines. For instance, it comes with dual boilers that allow steam and brewing functions to be heated independently, so that each function can be maintained at the exact temperature you want. McCarthy explains that by doing this the espresso is extracted at the right pressure (which can range from 4 bars to 14-16 bar at the end) and reduces the chance of overextraction. In addition, the machine has a “proportional-integral-derivative” or PID control that monitors and stabilizes the boiler or thermoblock temperature more accurately than a simple electromechanical thermostatic switch. This results in more consistent shots, and an earlier recovery time between each cup of espresso. It is also an excellent idea to find a machine that is able to be opened to perform regular maintenance and repairs, since espresso drinkers are often interested in the workings of their equipment. This is particularly important when it comes to a machine that will be frequently used, since frequent usage can cause parts to wear out. For example the espresso machine we tested could be opened to replace the drip tray and brew basket to ensure quick and easy cleaning. Cleaning Made Easy A professional espresso machine has numerous internal passages and chambers that are essential to keep them clean. Over time, grounds, coffee oils, and water mineral deposits can build up, affecting the quality of the final espresso cup as well as the overall performance of your machine. Regular cleaning can prevent these toxins from accumulating and ensure consistent water flow and the highest extraction pressure and a great flavor. Utilizing a specially-designed group head cleaning brush with bristles that penetrate into crevices can help get rid of stubborn residue. Regular use of a cleaning product can also help break down and dissolve coffee oils, ground particles, and other contaminants. Additionally, some espresso machines require periodic backflushing, which entails blocking the portafilter by blind filters and pushing water back through the system to clean the shower head, group head screen, and valves. Backflushing is easier when you use the appropriate tools and follow the manufacturer's instructions. For regular espresso drinkers, the use of a reusable group head cleaning tool can make routine maintenance much easier. These reusable brushes are available in various sizes and shapes. They are designed to clean all parts of the machine like gaskets, valves and ports. They are typically constructed of stainless steel and have a small holder that can be filled with water or replenished whenever required. Some tools include a built-in reservoir to keep the cleaning solution in storage when not being used. Descaling solutions enhance the performance of espresso machines as well as their user-friendliness particularly when they are used in high-volume settings. These liquid descalers remove calcium and limescale that block and hinder water flow and reduce the overall taste of espresso. The user can soak the parts or backflush their system with these products, which are more effective than citric acid cleaners in eliminating mineral buildup. Think about the features that matter most to you and your company when choosing the most suitable espresso machine. For instance, if want to be able to alter the temperature of your water and brew size for specific drinks, you might prefer a manual espresso maker with more adjustable settings. On the other the other hand, if your preference is for an avid espresso drinker but would like to enjoy a great tasting coffee at home, a semiautomatic or fully automated espresso machine might be the ideal choice. Ease of Maintenance The ease of maintaining your espresso machine is dependent on the type. Certain machines require more manual work while others are less demanding. The best way to determine this is to look at the degree of automation. Espresso/cappuccino machines fall into three categories: semi-automatic, fully automated, and super-automatic. Semi-automatic machines allow the barista some control, but they do not offer much control. A fully automatic machine requires less involvement from the operator, but still requires the operator to grind and then tamp before pulling the shot. Super-automatic machines are fully automated and make espresso and espresso-based beverages by pressing a single click of one button. If you are considering purchasing a semiautomatic or fully automated professional espresso machine, you should consider the number of customers your business expects to serve during peak times. This will help you decide the size of commercial espresso machine to purchase. If you plan to serve 120 drinks from 8-10 AM, then you'll need a semi-automatic espresso machine capable of handling the volume of orders. You'll need to determine the frequency at which you should descale your machine. Some manufacturers recommend descaling every month at least using a mix of warm water and vinegar. If you don't regularly descal your machine, it might develop issues such as blocking or a change in flavor. Many of the more advanced espresso machines available feature a dual boiler, with one boiler for brewing and another to steam. This allows the steam wand and group head to be heated at separate temperatures, allowing you to continue to steam milk for drinks while your shots are being brewed. This is particularly useful for cafes with a lot of customers who need to serve lots of different varieties of coffee and cappuccino. Other features that you can see in more sophisticated espresso machines include a hot water dispenser and an automatic rinsing cycle and programmable user preferences for the kind of cappuccino and coffee you make most frequently. These features can save time and money, especially in high-volume settings where consistency is essential. There is also the possibility that the machine comes with an inbuilt or attached coffee grinder and a nozzle that can be used to serve hot or frothed steamed milk. Ease of Repair When it comes to a commercial espresso machine reliability and repair ease are crucial aspects. Commercial espresso machines are designed to withstand the rigors of heavy use and are constructed from sturdy materials. They are more likely to have warranties and other protections from damage. Espresso machines for home use are typically constructed of less expensive materials and are prone to break more easily. Many commercial espresso machines also require UL-listed and have a NSF seal in order to comply with health and building department standards. These requirements help ensure that the equipment is safe for employees as well as customers. This is especially true for espresso machines that make a high volume of drinks. Choose a machine that is made of stainless steel or FDA-approved components to avoid chemicals leaching into coffee. There are several different types of professional espresso machines including manual, semi-automatic, and fully automated. Each machine type has its particular advantages and disadvantages but all are built to make delicious coffee. A manual espresso machine requires the barista to generate the pressure using their hands and arms which can be a challenge to master. They are also less popular, and therefore they could be more difficult to locate parts for should something go wrong. Semi-automatic espresso machines provide an ideal compromise between human control and mechanised consistency. The barista still has to grind and tamp the beans, but the pump controls the pressure and temperature of the water to avoid over-extraction. Fully-automatic espresso machines are similar to semi-automatic machines, but they are also able to deliver hot and steam at the push of one button. This can help save energy and time, and also increase production capacity. Regardless of which type of espresso machine you pick it is crucial to instruct your staff on how to use it correctly. This will increase the quality of your coffee as well as increase efficiency. It could take some time for new staff members to learn how to grind, tamp and extract the right shots However, the investment will pay off in time as you provide your customers with an consistently high-quality cup of espresso.
