Spread the love

Are you thinking about getting a home espresso machine? If you have ever wanted to brew your own espresso at home, then you definitely need to check out this guide. 

In this article, we discuss everything you need to know about espresso – what it is, how it is made, the importance of 15 bar pump pressure, and more. 

What is an Espresso? 

Espresso is not a type of roast or coffee bean – it is actually a coffee-making method in which a small amount of nearly boiling water is forced under pressure through ground coffee beans. 

In fact, espresso coffee can be made using different coffee beans and roasts; however, some types of coffee taste better than others. 

How Is It Made? 

Before you start brewing, you have to finely grind the coffee beans into a fine, powdery consistency. 


Then, you place this powder into the portafilter – the handle which holds the ground coffee – and use a tamper to press the grounds down. 

Using the correct amount of pressure is crucial when tamping the ground coffee. Then, hot water is pushed forcibly through the coffee grounds at high pressure. The espresso drips out at the bottom of the portafilter, ready to be used for the desired drink. 

Why is a 15 Bar High-Pressure System Important? 

If you have too little pressure, your espresso will taste weak and under-concentrated; on the other hand, if you have too much pressure, your espresso will taste bitter and over-extracted. 

For this reason, most people consider the sweet spot for making delicious-tasting espresso shots as 15 bars of pump pressure.

The industry standard for an espresso machine is 9 bars of pressure, and while this can create a good espresso, many contend that 15 bars make the best brews. 

2 Best Espresso Coffee Machines with a 15 Bar High-Pressure System

  1. De’longhi EC155 15 BAR Pump

    This Italian-made espresso machine combines ease of use and accessibility. It comes with a cup warmer, frother, and a basic cup and filter system.

    It features a 3-in-1 filter holder that works for both espresso pods and ground coffee, as well as the patented DeLonghi Cappuccino Frothing Wand for easy milk frothing.

    It also features separate thermostats that enable both water and steam pressure to be controlled for an excellent cup of espresso every time.

    Concentrating a high amount of pressure through coffee grounds is important when making espresso.

    The De’longhi EC155 15 BAR Pump Espresso and Cappuccino Maker can exert 15 bars of pressure, which is remarkable considering the machine’s price and size.

    Typically, this amount of power is reserved for more expensive and much larger machines, like those you’d find at a café.

    The De’longhi EC155 also has a good capacity grounds storage bin, shot bandwidth, and water storage tank.

    This espresso machine is capable of simultaneously pulling two shots. Furthermore, its 35-ounce water storage tank is more than enough to pour quite a few 1 to 2-ounce espresso shots.

    This espresso machine is also very easy to clean and maintain; the water reservoir and drip tray are easily removable.

    The inside mechanisms are also cleanable using the manufacturer’s protocol, which is easy enough for most users.

    The black and stainless steel exterior is stylish and compact, making it a perfect addition to any kitchen.

    The De’longhi EC155 15 BAR Pump Espresso and Cappuccino Maker is also great for beginners – it self-primes on startup at the touch of a button, making it easier to use than more expensive and more complicated espresso machines.

    Moreover, the tray is adjustable for various sized mugs and cups. The Mr. Coffee Cafe Barista Espresso and Cappuccino Maker is conveniently designed.

    The buttons on the front of the machine are labeled clearly with the corresponding drink, and there are manual and automatic options.

    Moreover, the milk reservoir fits within the unit and it’s removable, so leftover milk can be stored in the fridge when not being used. The frother also has a clearly labeled knob that regulates how much froth goes into each drink.

    A measuring spoon is also included – this also doubles as a tamper which is used to press the coffee grounds into the portafilter.

    There are also two filters that fit into the portafilter – one for a single shot and another for a double shot.

    Furthermore, there are two drip trays – one tray sits within the unit underneath the portafilter which caters to full-sized mugs.

    The second tray pulls out from underneath the milk reservoir, creating less room for the espresso to spill out for those who want to use smaller cups.

    The water reservoir in the back is also removable, making it easy for users to fill it up, dump out any excess water, and clean it.

    The setup process is also simple and straightforward. To make an espresso, you simply have to pick the filter size you want (single or double) and place it into the portafilter.

    Next, scoop the grounds into the filter and press them down with the tamper until they are about 1/8 inch below the top of the filter (according to the manual’s recommendation).

    Then, attach the portafilter to the machine and place a small cup on the pull-out drip tray. Then, press the Espresso button – one time for a single shot and twice for a double – and let the machine do its work.
