Coffee and Espresso Machines
Espresso machines use pressure to push water through finely ground and tamped coffee beans. They produce a rich, tasty brew.
Experts at the Good Housekeeping Institute recommend models that brew at the minimum pressure of 9 bars to get the best extraction. Beware of brands that advertise more pressure than is required.
Types
The espresso machine, also called a coffee or espresso maker, makes the concentrated, higher-quality coffee of your favourite cafe drinks using an average of 9 bars of pressure. They come with a range of options, such as the control of temperature and brew strength, programmable brewing and multiple sizes of drinks. They can also have manual or automatic steam wands to create texture-rich milk for latte art. They can be found in three major kinds of espresso machines comprising semi-automatic, automatic and super-automatic models. Each espresso machine comes with its own particular level and kind of automation.
The most popular espresso machine used in specialty coffee shops is semi-automatic models. This gives baristas complete control over the brewing process however, it's not as user-friendly as a fully automatic machine. You still need to grind beans, fill and tamp the portafilter and adjust the extraction duration for the best espresso shot of the highest quality.
Automated machines come with built-in mills that measure and tamp your grounds. They automatically dispense the appropriate amount of water needed to extract the espresso, and often come with a programmable drink size function. They were the most common espresso machine types in our lab tests, and they provide a great balance of consistency and human control.
Functions
If you opt for a pump-driven machine or a steam-driven one, you'll have a reservoir that holds the water used to make your coffee. There's also heating elements that heat the cold water, generating the high pressure needed for extraction of coffee from grounds.
When the brew lever is lifted, it triggers the water inlet cam that seals the valve to prevent pre-infusion. This ensures that only intensely pressurized hot water flows through the portafilter and into ground coffee. The water takes around 25 seconds to turn into espresso.
The hot-water tubing, referred to as the insulated tubing, runs from the reservoir up to the spout at the top of your machine. The resistance heating element will heat the water as water moves through the aluminum tube and warming plate.
After the spout has been 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 milk to make drinks made with espresso, like cappuccino or Latte.
Automated machines take the guesswork out making a cup of coffee. They are simple to use, programable, and can measure and grind beans as well as tamp down. They generally have the best overall performance in our Lab tests because they are easy to operate and don't require a lot of users' skills.
Materials
Inside an espresso machine, you'll find a plethora of copper tubes and boilers made of stainless steel. There's also a sophisticated firmware. They may appear complex, but at their core they perform one simple thing: force hot water through a finely-ground coffee.
When choosing an espresso maker, think about dimensions and space requirements, beverage options, energy-saving options, and brewing accuracy. Also, look for a steam knob that will activate the steam wand that can be used to froth milk and making Latte art. The front of the machine is equipped with a gauge for pressure that can show the operating pressure for the boiler and pump. You should search for a coffee machine that has two needles to see the minimum and maximum pressure.
If you're looking for more then just espresso then choose one that has different sizes of brew. This includes the ristretto. There are also models that come with an insulated frothing hopper that makes it easy, hands-free frothing. You can also switch between various kinds of milk easily. Select a model with an integrated softener in case you have hard water. This will help prevent mineral build-up and to keep your espresso fresh.
Certain manufacturers employ a thermostat that is digital, integral and proportional in order to maintain a certain temperature range when brewing espresso. This feature helps ensure a consistent, high-quality cup of espresso every time. It also saves on energy costs since the machine only operates when it's necessary.
Maintenance
As coffee and espresso machines are more widely available to home use, the proper maintenance of this equipment becomes more essential. The right equipment can make the world of distinction in your cup of coffee, however that's only true if the machine is functioning properly.
A regular cleaning and maintenance routine should include everything from cleaning the steam wand and group head, to descaling, to changing the water filter on a regular basis. As a rule of thumb that you make between two and five cups of coffee each day, you should clean the majority of your machine at least once per week. However, some components of the machine, such as the water tank and grinder should be cleaned every two to three weeks.
Additionally, you should backflush your machine every week. This is done by locking the portafilter into place and running the brew cycles several times. This will help remove any coffee grounds or oils that remain. You can also clean the portafilter by using brushes and cleaners that is specifically made for espresso machines.
