The top espresso machines are simple to use, easy to clean and can make powerful and balanced shots. How do you choose the best espresso machine for your home?

This Breville model, with its quick-heating thermocoil design and digital ease of use is perfect for anyone who doesn't want to develop barista skills but wants excellent coffee at home.

Pump-driven

Pump-driven machines use an electric pump to deliver the force required to make espresso. These machines typically either accept water from the mains supply, common with commercial installations or a reservoir which is filled manually (common with household and smaller commercial espresso machines). Pumps are usually solenoid pistons, which can generate high pressure. Some espresso machines driven by pumps have a fixed flow control and others let you alter the pre-infusion or the brewing pressure.

These are the most popular machines, and are perfect for anyone who wants an consistently high-quality, consistent cup of coffee. They are also easier to clean and maintain than other types of machines however, they require a certain amount of electrical power and a space near an outlet.

There are two basic types of semi-automatics and super-automatics. Semi-automatics let you control how long the shot is pulled for through a manual switch or a programable function. In addition, you are able to adjust the grind setting and make sure that the coffee is tamper-proof. Some semi-automatics are rotary, while others are vibrating. Rotary pumps are quieter however they require a constant flow of pressurized liquid.

A vibrating pump, on the contrary, begins with a quiet start. However, it can make a loud noise once water is added to the machine. Both types have their pros and cons and you should pick the one that suits your needs best.

Pump-driven machines come in a variety of sizes and price ranges. The most expensive machines are usually super-automatic, and have multiple boilers that separate the water used for brewing and steaming. The heat exchangers of these machines can be set to different temperatures, allowing for some variation in the flavor of the espresso. This extra feature makes them a great option for busy baristas at home however, it can increase their price. The middle option is a semi-automatic which is a great value but does not offer the same consistency and flexibility as other options.

Steam-driven

Steam-driven machines utilize an easy method to create an intense espresso. Within an airtight tank, steam is heated to create pressure that is transferred to the coffee grounds to make espresso. This is similar to the process that happens in a stovetop Moka pot. These machines are still in use today due to their cost-effectiveness and small size. However, these models aren't able to reach 9 bars of pressure needed for authentic espresso. These models are best for those who are just beginning with homebrewing or those who don't worry about making the perfect espresso.

The earliest example of a steam-driven machine is the 1878 compensation siphon balancer developed by German engineer H. Eicke. Steam is created by this machine, which is used to push boiling beans through an aerator. The water is then released by heating from an open flame. This produces a powerful shot, however it does not meet the high standard of consistency that a lot of espresso enthusiasts like.

The next breakthrough came with Luigi Bezzera's 1901 patent improvements. His invention was able lower the temperature of the boiler, which allows for more constant pressure and temperature control. Bezzera included a piston device to help make this machine semiautomatic. The only issue was that it required the barista time to grind, measure and tamp the beans by hand.

This led to the creation of a pump-driven espresso machine. In contrast to the steam-driven machines of the past that were heated with an open flame, this type of machine has an electric pump that is capable of producing the high pressure needed for brewing espresso. These machines can accept water from a cold line, which is common in commercial establishments. They also have the option of using an additional water tank that has to be filled manually.

They also come with two temperature settings, which are controlled by the push of a button. One button activates the brew thermostat, and the other switches on the steam thermostat. This kind of machine is more precise than older steam-driven machines and can make consistent shots for less than the cost of more expensive models.

Semi-automatic

If you're looking for an easy method of making espresso with less hassle the semi-automatic machine is the solution. It eliminates the need for barista-level education by automatizing the grinding extraction, and tamping processes to produce consistently good results. It does not complete all the work for you. You still need to grind the beans, tamp them down in the portafilter and then push the water through.

This is the reason that many professional and amateur coffee drinkers prefer a semi-automatic machine, as they enjoy the feeling of being in control throughout the process of brewing. They also come with an affordable price compared to their fully-automated counterparts, and they tend to be more reliable, as well.

These espresso machines are typically found in non-specialty shops and in the homes of coffee drinkers who are willing spend more money for convenience. Dual boilers permit the steam and brewing process to be kept separate. One is used for heating, while the other is used to prepare your preferred beverage. Some models have a built in grinder which can save the user a lot of time.

The espresso grinder built into the machine is often limited in its settings, which can be frustrating for those who wish to alter the process of brewing their own espresso. A better solution is to combine a semi-automatic espresso maker with an external grinder for full control over the grind size and dosage.

If you're considering a semi-automatic espresso machine, make sure to look for one with a top-quality electric pump with low-noise, and precise temperature regulation through the PID controller. PID is an element of technology that's typically used in immersion circulators as well as high-end toaster ovens. espresso coffee machines uk can help stabilize a brewing kettle by monitoring the temperature changes throughout the heating process.

A good semi-automatic espresso machine should also have an efficient steam wand to create microfoam, and the capability to switch between steaming and brewing modes quickly (if it does not have two boilers). With all of these features, a high-quality semi-automatic espresso maker is a great option for those who wish to save the time and money of learning to make coffee of a high-quality, but enjoy some degree of tinkering with the process.

Manual

Manual espresso machines operate with levers that push pressurized coffee grounds through a bed. This produces extremely concentrated shots. They are generally less expensive than semi-automatic and fully automatic counterparts, making them popular for those who appreciate a fine cup of coffee.

Manual espresso machines require more focus and expertise from the operator to maximize their potential. It is also important to select the correct grinder and ensure that the brew percentage is right.

Although some may be able to find the process of learning in operating a manual machine frustrating, for those with the right capabilities, it's worth the effort. Adrian Lini, CHOICE's expert barista, says that if you have the patience and the right tools manual machines can make the best espresso.

In recent years, espresso machines that are operated by hand have improved in both appearance and function with more advanced features like digital pressure gauges that allow users to track the pressure of extraction. Charles, who works at Flair Espresso, explains that these machines can also be connected by Bluetooth devices to draw graphs of flow rate which can help users to understand how varying variables during extraction can affect the overall outcome.

There are two types of manual espresso machine which are spring-piston and direct. Direct levers have a spring inside their group heads that helps increase pressure while making espresso. They're more expensive than spring-assisted machines, but can still be easier to operate.

Springs piston machines are limited to the steam valve in their group head. They're much more user-friendly than direct lever machines, but don't offer as much control over the brewing process. The best machine for you will be based on your budget and personal taste. Whichever one you choose a manual espresso machine will require a few necessary accessories, including a kettle, a coffee grinder and a portafilter equipped with a removable metal dispersion screen.
