Coffee and Espresso Machines
Espresso machines make use of pressure to push water through finely ground and tamped coffee beans. They create a rich and delicious cup.
Experts from the Good Housekeeping Institute recommend models that brew with a minimum pressure of 9 bars in order to ensure the highest extraction. Beware of manufacturers who claim they use more pressure than what is required.
Types
The espresso machine, sometimes called a coffee and espresso maker, makes the most concentrated, high-quality coffee of your favorite cafe drinks with an average of 9 bars of pressure. These machines tend to have various features, including temperature control and brew strength, programmable brewing, and multiple sizes of drinks. They may also include steam wands, either manual or automated, to create an latte with a texturized milk. There are three types of latte art: semi-automatics, super-automatics and automatic. Each espresso machine comes with its own specific level and type of automation.
The most popular espresso machine model for specialty coffee shops is the semi-automatic model. This allows baristas to have full control over the brewing process but it is not as user-friendly as an automated or fully automatic machine. To get the best espresso, you have to grind the beans, fill the portafilter, tamp it down, then adjust the time of extraction.
Automated machines are equipped with a built-in grinder which measures and mill the grounds for you. They automatically dispense the appropriate amount of water needed to extract the espresso, and often have a programmable beverage size function. They were the most commonly used espresso machine in our lab tests and they offer a good combination of consistency and human control.
Functions
You'll need a reservoir to hold the water you use to make coffee, irrespective of whether you opt for a steam-driven or pump-driven machine. You'll also have an element to heat up the cold water to create the pressure necessary to extract coffee from ground.
When the brew lever is raised it triggers the water inlet cam to seal the pre-infusion valve so only intensely pressurized hot water flows through the portafilter and into ground coffee. It takes around 25 seconds for the water to be brewed into espresso.
The hot-water tubing, also known as the insulated tube extends from the reservoir to the spout located at the top of your machine. The resistance heating element heats the water as it passes through the warming plate made of metal and the aluminum tube.
When the spout is activated, you'll put your cup under the spout, which will catch the espresso as it flows through the portafilter into your cup. The coffee maker is also likely to have a steam wand, that you can use to heat and froth the milk for espresso-based drinks such as cappuccino or the latte.
Automated machines remove the guesswork involved in brewing. They are simple to operate, programmable and can measure and grind beans as well as to tamp down. In our Lab tests, they tend to perform the best because they're simple to use and don't require a lot of user skills.
Materials
Inside an espresso machine you'll find a vast array of copper tubes and stainless steel boilers. There's also an intelligent firmware. Although they appear to be complex however their main purpose is to make hot water into finely ground coffee.
When purchasing an espresso machine, you should consider the size and space requirements, as well as drink options, energy saving options, and brewing precision. Also look for a knob that can activate the steam wand, which is used for frothing milk and creating artwork with latte. The front of the machine has a gauge for pressure that can provide the operating pressure for the boiler and pump. You should choose a coffee machine that has two needles in order to determine the minimum and maximum pressure.
If you want to make more than espresso, pick a machine that offers different sizes of brews, including ristretto. There are models that have the ability to remove the milk hopper for hands-free, hassle-free frothing and the ability to effortlessly switch between various types of milk. If you're dealing with hard water, you should choose one with an integrated softener for your water to prevent the buildup of minerals and keep your espresso tasting fresh.
Certain manufacturers employ a thermostat that is digital, integral and proportional to keep a certain temperature range when making espresso. This feature helps ensure a consistent, high-quality cup of espresso every time. This feature also reduces cost of energy since the machine only runs if necessary.
Maintenance
Since espresso and coffee machines become more widely available to home use, the proper maintenance of these machines becomes more important. The best equipment can make an enormous difference in the quality of your coffee but only if it is properly maintained.
Regular maintenance and cleaning espresso machines needs to consist of everything from cleaning the steam wand, group head and water filter, as well as descaling and changing the water filter regularly. If you're making between two and five cups of coffee every day, it's recommended to clean the machine's main parts every week. However, some components of the machine, like the water tank and the grinder are required to be cleaned every two or three weeks.
In addition, you should backflush your system every week. This involves placing the portafilter in its place and running the brew cycles many times. This allows you to get rid of any coffee grounds or oils that are left behind. You can also clean the portafilter using a brush and cleaner specifically designed for espresso machines.
Maintaining your coffee machine and espresso properly will help it last longer. It is important to take care of your expensive espresso machine.
