What to Look For in a Professional Espresso Machine You'll want a machine which can be controlled the pre-infusion, which is essential to develop aroma and flavor. PID temperature control is an option that coffee experts are looking for in a professional espresso machine. If you're planning to hire baristas who have no experience, you'll require a machine that's easy to operate and easy to train new employees on. This is essential for those who plan to operate an open-air coffee shop. Ease of Use As you could have guessed from its name the espresso machine is professional and is designed to be easy to operate and maintain. It features an integrated grinder that automatically grinds fresh coffee beans right into the portafilter, a digital temperature control to ensure the best extraction as well as the manual steam wand that is used to create microfoam to create coffee art. It also comes with an instrument to help you determine the hardness of water as well as an AquaClean filtering system to eliminate scale. It's a great option for home baristas since it offers a balance between manual and automatic operation. You can make a shot of coffee like professional baristas (although there is a slight learning curve). The built-in coffee grinder allows you experiment with the grind size to adjust the grind size. Additionally, the manual steam wand is a simple way to create frothy lattes and cappuccino milk. The machine also has a removable, dishwasher-safe milk hopper to make cleaning up after each use easy and easy. While this model is intended to be used at home but it comes with some sophisticated features that distinguish it from espresso machines used by professionals. For instance, it comes with dual boilers that permit steam and brewing functions to be heated separately, so each function can be maintained at exactly the desired temperature. McCarthy says that this will ensure the espresso is extracted at the proper pressure (which can vary from 4 bars at beginning and 14-16 bars when finished) while minimizing the risk of over-extraction. 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 espresso cup. You should also look for an espresso machine that can be opened to perform routine maintenance or repairs. Espresso enthusiasts are usually interested in the inner workings and mechanics of their equipment. This is particularly important for a professional espresso machine that will be used frequently because frequent use could result in wear and tear on the parts. The espresso machine we tested for example, can be opened up to replace the brew group container and drip tray for fast and efficient cleaning. Cleaning Made Easy A professional espresso machine has many chambers and internal passageways that are essential to keep them clean. Over time grounds used for coffee, coffee oils and water mineral deposits may build up, affecting the taste of the final espresso cup as well as the overall performance of your machine. Regular cleaning can prevent the accumulation of these contaminants and ensure consistent flow of water, optimum extraction pressure, and good flavor. A specially designed cleaning brush with bristles that are designed to get into crevices can help remove stubborn stains. Regular use of a cleaning product can help break down and dissolve coffee ground particles, oils, and other contaminants. In addition, some espresso machines require periodic backflushing, which involves blocking the portafilter by a blind filter and forcing water back through the system to clean the group head, shower screen, and valves. Backflushing is easier using the correct tools and follow the manufacturer's instructions. A reusable tool to clean the group head will make maintenance routine easier for espresso drinkers. These reusable brushes are available in a variety of shapes and sizes and are designed to clean all parts of the machine, including gaskets, valves, and ports. The brushes are typically made of stainless steel, and have an holder that is small enough to be easily filled or refillable whenever required. Some tools include built-in reservoirs to keep the cleaning solution in storage when not being used. Descaling solutions can dramatically improve espresso machine performance and ease of use particularly in high-volume settings. These liquid descalers eliminate calcium and limescale that clog water flow and reduce the taste of espresso. These products can be used to backflush or soak areas of the system. They are more effective in getting rid of mineral buildup than citric acids. Consider the features that are most important to you and your business when choosing the best espresso machine. If you're looking to control the temperature of your water as well as the the amount of brew you can use for certain drinks, a manual espresso machine with more adjustable settings might be the best choice. If you're an avid espresso-drinker and want to enjoy great coffee at home in a convenient way, a semi-automatic espresso machine or fully automated espresso maker might be the best choice. Ease of Maintenance The kind of espresso machine you have will determine the ease to maintain. Some machines require more manual labor and others are more demanding. The best way to determine this is by looking at the degree of automation. Espresso/cappuccino machine types are divided into three categories: semiautomatic, fully automated and superautomatic. Semi-automatic machines give the barista the control, but does not provide an excessive amount of automation. A fully automated machine is less hands-on but still requires the operator to grind, tamp, and pull the shot. best coffee espresso machine -automatic machine is completely automated, making espresso and espresso-based drinks from just a single press. If you are considering purchasing a semiautomatic or fully automated professional espresso machine you should consider the number of customers that your business expects to serve during peak hours. This will help you determine what size commercial espresso machine to buy. If you plan to serve 120 drinks between 8 to 10 AM, then you'll require a semi-automatic espresso system that can handle the volume of orders. You'll need to decide when you'll need to descale your machine. Some manufacturers recommend decaling every month at least with a mixture of warm water and vinegar. If you don't regularly descale your machine, it could experience issues like clogging and altered flavor. Many of the most advanced espresso machines feature a dual boiler system. One boiler is for making coffee, and the second to steam. This allows the steam wand as well as the group head to be heated at separate temperatures, allowing you to continue to steam drinks while your shots are brewing. This is particularly useful for busy cafes who have to serve a variety of varieties of cappuccino and coffee. Some of the other features you can discover on a more sophisticated espresso machine are hot water dispensers and an automatic rinse cycle and user preferences that can be programmed for the type and amount of coffee or cappuccino that you typically make. These features can help you save time and money in large-scale settings where consistency is essential. There is also coffee grinders built into the machine or attached to it, and an nozzle to dispensing hot or frosty milk. Ease of Repair When it comes to commercial espresso machines, the durability and ease of maintenance are key aspects. Commercial espresso machines are built to withstand heavy use and are constructed of robust materials. They are also more likely to come with warranties and other protections against damage. Espresso machines for home use however, are typically made with cheaper materials and may be more susceptible to breaking down. Additionally the majority of espresso machines used in commercial establishments have to be UL listed and carry an NSF seal to be in compliance with health department and building standards. These requirements ensure that the equipment is safe for employees as well as customers. This is particularly applicable to espresso machines that produce a lot of drinks. Choose a machine that is made of stainless steel or FDA-approved components to avoid chemicals leaching into coffee. There are a variety of professional coffee machines including semi-automatic and fully automatic. Each has its own advantages but they all make delicious coffee. It can be a challenge for a barista to master a manual espresso machine, because they have to make the pressure themselves using their arms and hands. These machines aren't as popular and may be harder to locate replacement parts for in the case of an issue. Semi-automatic espresso makers are a good option for those who wish to control their machines, while ensuring consistency. The barista must grind and tamp the beans, but the pump controls water pressure and temperature to prevent over-extraction. Fully-automatic espresso machines are like semi-automatic ones, but they also have the ability to dispense steam and hot water at the touch of a button. This can save energy and time, as well as increase production capacity. It is important that your staff members know how to use the espresso machine, regardless of the type you select. This will enhance the quality of your coffee as well as its effectiveness. It might take a while for new staff members to understand how to properly grind, tamp and extract shots, but this investment will pay off in the long run by providing your customers with consistently high-quality espresso.
