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 the development of flavor. Many coffee experts also look for PID temperature control in the best machines.
If you are planning to hire baristas who have no experience, you'll need a machine that is easy to learn. This is important for those who plan to operate an open-air coffee shop.
Simple to Use
This professional espresso machine as you might have guessed by its name is designed to be easy to operate and maintain. It includes an integrated grinder which automatically grinds coffee beans into the portafilter. It also has a digital temperature control for optimal extraction and the manual steam wand that can create microfoam. It also has a test strip that helps you measure the water's hardness, and an AquaClean filtration system to reduce the scale.
It's a great option for baristas at home because it offers a balance between automatic and manually operated operation. You can take a shot of espresso like a professional (although there is a little learning curve). The built-in grinder allows you to experiment with the size of your coffee grind and fine-tune the process while the manual steam wand allows you to make frosty milk for your lattes and cappuccinos. The machine comes with a dishwasher-safe, removable milk hopper that makes cleaning up after use easy and convenient.
While this model is intended for home use, there are some advanced features that set it apart from professional espresso machines. For instance, it has two boilers that allow for the steam and brewing functions to be heated separately, so 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 can vary from 4 bars at the beginning, and 14-16 bars after it is 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 results in more consistent shots and a quicker recovery time between each cup of espresso.
espresso makers 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 fascinated by the inner workings of their equipment. This is especially important when it comes to a machine that will be frequently used, since frequent use can cause components to wear out. For instance, the espresso machine we tested can be opened to change the drip tray and brew basket to ensure quick and easy cleaning.
Cleaning Made Simple
It is important to keep the interior of an espresso machine that is professional clean. Coffee oils, coffee grounds used, and water minerals can build up over time, affecting the quality of the final espresso cup and the overall performance of the machine. Regular cleaning will prevent these contaminants from accumulating and ensure consistent water flow, optimum extraction pressure, and a great flavor.
A special cleaning brush with bristles that are designed to get into crevices can help remove stubborn stains. Regular use of a cleaner can also help break down and dissolve coffee ground particles, oils, and other contaminants. Additionally, certain espresso machines require periodic backflushing, which involves blocking the portafilter with blind filters and pushing water back through the system to clean the shower head, group head, screen, and valves. Using the proper tools and following the manufacturer's guidelines for backflushing can improve overall espresso machine cleanliness and maintenance.
A reusable tool for cleaning the group head can make routine maintenance easier for espresso drinkers. These reusable brushes come in different sizes and shapes and are designed to clean different parts of the machine, including gaskets, valves and ports. The brushes are typically constructed of stainless steel and come with an holder that is small enough to be easily filled or refilled when needed. Some tools come with an in-built reservoir for storing the cleaning solution when not being used.
Descaling solutions improve the performance of espresso machines and their user-friendliness especially when employed in high-volume settings. These liquid descalers get rid of calcium and limescale that block and impair water flow and diminish the overall flavor of espresso. Users can either soak parts or backflush the system using these products, which are more effective than citric acid cleaners in getting rid of mineral buildup.
Take into consideration the features that matter most to you and your company when selecting the ideal espresso machine. For instance, if you would like to customize your water temperature and brew volume for specific beverages, you may prefer a manual espresso maker with more adjustable settings. If you're an avid espresso-drinker and want to enjoy a great cup of coffee at home in a comfortable way, a semi-automatic espresso maker or fully automated espresso maker may be the best option.
Maintenance Ease
The type of espresso machine you own will determine the ease to maintain. Some machines require an extensive amount of hands-on effort while others require less hands-on. You can tell this by looking at the degree of automation. Espresso and cappuccino machines are classified into three categories: semiautomatic, fully automated and superautomatic. A semi-automatic machine gives the barista control, but not an excessive amount of automation. Fully automated machines require less operator involvement, but still requires that the operator grind, tamp and pull the shot. Super-automatic machines are completely automated, preparing espresso and espresso-based drinks from one button press.
If you're considering purchasing semi-automatic or fully automated professional espresso machine, be sure to take into account the number of customers your business anticipates serving during peak hours. This will help you decide what size of a commercial espresso machine to purchase. For instance, if you plan to serve 120 drinks between 8 and 10 AM, you'll want to purchase a semi-automatic machine that can keep up with the influx of orders.
You'll need to determine how often you should descale your machine. Some manufacturers recommend descaling at least once per month using a combination of vinegar and warm water. If you don't frequently descale your machine, it may develop issues like clogging and altered flavor.
A lot of the most sophisticated espresso machines come with a dual boiler system. One boiler is for making espresso, while the other is for steaming. This allows the steam wand as well as the group head to be heated at distinct temperatures, allowing you to continue to steam milk for drinks while your shots are being brewed. This is especially useful for cafes with a lot of customers who require a variety of kinds of coffee and cappuccino.
Other features that you can see in more sophisticated espresso machines are a hot-water dispenser and an automatic rinsing cycle, and programmable user preferences for the kind of coffee and cappuccino you use the most often. They can save you time and money, particularly in high-volume settings where consistency is key. You may also find that the machine has an integrated or attached coffee grinder and a nozzle for dispense hot or frozen steaming milk.
Ease of Repair
The durability and ease of maintenance are key factors when it is about commercial espresso machines. Commercial machines are designed to withstand high usage and are typically constructed of durable materials that can last for years. These machines are more likely to have warranties and other protections from damage. Espresso machines at home are typically constructed from cheaper materials and are prone to break more easily.
In addition, many commercial espresso machines are UL-listed and carry an NSF seal to be in compliance with standards of the health department as well as building regulations. These requirements ensure that the equipment is safe for employees and customers. This is particularly true for espresso machines that produce an enormous amount of drinks. Choose a machine constructed of stainless steel or FDA-approved materials to prevent chemicals leaching into the coffee.
There are several different types of professional espresso machines, including semi-automatic, manual and fully automatic. Each has its own pros and cons however, they all make delicious coffee.
It can be difficult for a barista to master a manual espresso machine, as they must create the pressure themselves with their arms and hands. These machines aren't as popular and can be difficult to locate replacement parts for in the case of an issue.
Semi-automatic espresso machines offer a good compromise between human control and mechanized consistency. The barista still has to grind and tamp the coffee beans, but the pump controls the pressure and temperature of the water to prevent over-extraction.
Fully-automatic espresso machines are similar to semi-automatic models. However they also can dispense steam and hot water at the touch of one button. This helps save energy and time, and allow for a greater capacity of production.
No matter what kind of espresso machine you pick it is crucial to train your staff to use it properly. This will increase your coffee's quality and effectiveness. It might take a while for new staff members to learn how to properly grind, tamp and extract shots but it will pay dividends in the end by providing your customers with a consistently great cup of espresso.
