What to Look For in a Professional Espresso Machine You'll want a machine which has the ability to control the pre-infusion, which is essential for establishing aroma and flavor. PID temperature control is also an option that many coffee experts search for in a professional espresso machine. If you are planning to hire baristas with no experience, you will need a machine that is easy to learn. This is crucial when you are planning to operate an open-air coffee shop. Easy of Use This professional espresso machine, as you might have guessed by its name is designed to be easy to use and maintain. It has an integrated grinder which automatically grinds coffee beans into the portafilter. It also features digital temperature control to ensure optimal extraction and a manual steam wand to create microfoam. It also includes test strips that help you measure water hardness as well as an AquaClean filtering system to eliminate the buildup of scale. It is an excellent choice for home baristas because it is able to provide a balance of manual and automatic operation. You can take a shot of espresso like a professional (although there is a slight learning curve). The built-in grinder permits you to experiment with the size of your coffee grind and fine-tune the process while the steam wand manual allows you to make foamy milk for lattes and cappuccinos. The machine also features a dishwasher-safe, removable milk hopper that makes cleaning up after each use simple and convenient. While this model is intended to be used at home however, it has some advanced features that set it apart from espresso machines used by professionals. For example, it has dual boilers that allow the brewing and steam functions to be heated independently, so that each function can be maintained at the exact temperature you want. McCarthy says that this will ensure the espresso is extracted at the proper pressure (which is varying from 4 bars at the beginning and 14-16 bars when completed) while minimizing the chance 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 means more consistent shots and a faster recovery time between each cup of espresso. It's also recommended to look for a machine that can be opened to carry out routine maintenance and repairs, because espresso lovers are frequently interested in the workings of their equipment. This is especially important for a machine that will be used often, as frequent use can cause parts to wear out. The espresso machine we tested, for instance, is able to be opened up to replace the brew group basket as well as the drip tray for quick and convenient cleaning. Cleaning Made Easy A professional espresso machine has numerous internal passages and chambers that are important to keep them clean. Coffee oils, coffee grounds used, and water minerals can accumulate over time, impacting the quality of the final cup of espresso and the overall performance of the machine. Regular cleaning can stop these contaminants from accumulating and ensure consistent water flow and the highest extraction pressure and a good taste. A specially designed cleaning brush with bristles designed to get into crevices can help remove stubborn stains. Regular cleaning solutions can also aid in dissolving and breaking down coffee oils, particles and other contaminants. Some espresso machines also require regular backflushing. This involves blocking the portafilter with a blind filter, and forcing water through the system in order to clean the shower screen, group head, and valves. Backflushing is more efficient if you use the right tools and follow the instructions of the manufacturer. A reusable tool for cleaning the group head can make routine maintenance simpler for espresso users. These brushes are reusable and come in various sizes and shapes to efficiently clean various components of the machine, like valves, ports and gaskets. They are typically made from stainless steel and include an holder that is small for the cleaning solution, that is easy to fill or refill whenever required. Some tools even feature an integrated reservoir to store the cleaning solution after it has been in use. Descaling solutions boost the performance of espresso machines and their user-friendliness, especially when they are used in high-volume settings. These liquid descalers eliminate calcium and limescale, which block water flow and decrease espresso taste. These products can be used to backflush or soak parts of the system. They are more effective in removing the buildup of minerals than citric acids. Consider the features that are most important to you and your company when choosing the best espresso machine. If you'd like to be in control of the temperature of your water and the amount of brew you can use for certain drinks such as a manual espresso maker with more adjustable settings might be the best choice. On the other side, if you're an occasional espresso drinker and would like to enjoy great-tasting coffee at home, a semi-automatic or fully automatic espresso machine might be the ideal choice. Easy Maintenance The ease of maintenance of your espresso machine largely on the model. Certain machines require more manual work and others are more demanding. You can tell by taking a look at the level of automation. Espresso and cappuccino machines are classified into three categories: semiautomatic fully automated, and superautomatic. Semi-automatic machines give the barista the control, but does not provide much automation. Fully automated machines require less operator involvement, but still requires the operator to grind and then tamp before pulling the shot. Super-automatic machines are fully automated and create espresso and espresso-based drinks with a single push of the button. If you're purchasing semi-automatic or a fully automated professional espresso machine, be sure to consider the number of customers your company anticipates serving during peak times. This will help you determine the size of an commercial espresso machine you need to purchase. If you are planning to serve 120 drinks from 8-10 AM, then you'll require a semi-automatic espresso system that can handle the volume of orders. You'll also need to consider the frequency you should descale your coffee machine. Some manufacturers recommend decaling at least once per month using a combination of vinegar and warm water. If you don't frequently descal your machine, it may develop issues such as blocking or a change in flavor. Many of the more advanced espresso machines on the market come with a dual boiler system with one boiler used to make espresso and another one to steam. The steam wand can be heated separately from the group head and allows you to continue steaming milk while the shots are being made. This is particularly useful for busy cafes that need to serve lots of different varieties of cappuccino and coffee. Some of the other features you can get on a higher-end espresso machine are hot water dispensers as well as an automatic rinse cycle and user preferences that can be programmed for the type and quantity of cappuccino or coffee you are most likely to make. These can save time and money, particularly in high-volume settings where consistency is key. There is also the possibility that the machine comes with an integrated or attached coffee grinder, and a nozzle for dispense hot or frothed steaming milk. Repairs are simple Maintenance-free and durability are important factors when it comes to commercial espresso machines. Commercial espresso machines are built to withstand heavy usage and are constructed of robust materials. They are more likely to come with warranties and other safeguards against damage. Espresso machines at home are typically constructed of less expensive materials and can break down more quickly. Many commercial espresso machines need to be UL-listed and come with an NSF seal in order to be in compliance with health and building department standards. These requirements ensure that the equipment is safe for employees and customers. This is especially true for espresso machines which produce a significant amount of drinks. Choose a machine constructed of stainless steel or FDA-approved materials to avoid chemicals leaching into the coffee. There are a variety of professional espresso machines, including semi-automatic, manual and fully automated. Each one has its own advantages, but they all produce delicious coffee. It can be a challenge for a barista to master the manual espresso machine as they must make the pressure themselves using their arms and hands. These machines are less common and can be difficult to locate replacement parts in the event of malfunction. Semi-automatic espresso machines are an excellent compromise between human control and mechanised consistency. The barista must grind and tamp the beans however, the pump regulates the pressure and temperature of the water to avoid over-extraction. Fully-automatic espresso machine models are similar to semi-automatic models. However they also have the ability to dispensing steam and hot water at the push of the button. espresso makers coffeee.uk saves energy and time and allows for a greater capacity of production. It is crucial that your staff knows how to use the espresso machine, no matter the model you choose. This will enhance your coffee's quality and efficiency. It may take some time for new staff members to learn how grind, tamp and extract shots correctly, but the investment will pay off in time by providing your customers consistently excellent cups of espresso.
