Overview
The under-pressure brewing method is known for its utilization of high pressure to extract flavors from coffee grounds and is closely associated with the “Under Pressure” coffee brewing technique. This technique is commonly employed in espresso brewing, where water is forcefully pushed through densely packed coffee grounds.
Types of under-pressure brewing machines:
Espresso Machine
Espresso Machine is the most common under-pressure brewing method. That uses high pressured force to extract a concentrated and flavorful shot of coffee.
Moka Pot
The Moka pot is a stovetop coffee maker that uses steam pressure to push water through coffee grounds. It typically consists of a bottom chamber for water, a middle funnel-shaped basket for coffee, and a top chamber to collect the brewed coffee.
AeroPress
The AeroPress is a manual coffee brewing device that utilizes both pressure and immersion brewing. It involves placing coffee and water in a chamber and then using a plunger to create pressure and force the brewed coffee through a filter.
A guide to brewing a coffee using the under-pressure method:
Regardless of the specific machine you choose to use, here is a commonly employed brewing method.
Grind your coffee beans
Start by grinding your coffee beans to a fine consistency. The exact coffee grind size will depend on your brewing equipment, but generally, it should be finer than what you would use for drip coffee.

Preheat your tools
Whether you’re using an espresso machine or any manual brewing tools, it’s crucial to ensure that they are adequately preheated. This step plays a vital role in maintaining a consistent brewing temperature from start to finish, leading to optimal flavor extraction of your coffee.
Prepare your tools
Prior to brewing, it is essential to ensure that your tools are both clean and dry. This is not only crucial for hygiene purposes but also because any residual coffee grounds left behind could potentially impact the flavor of your brewed coffee.
Start Brewing
Please note that the brewing process can vary when it comes to under-pressure brewing methods, so it is important to follow specific guidelines or instructions accordingly.
Monitor the extraction time
The extraction time for under-pressure brewing can vary depending on the specific brewing method being used. However, in general, under-pressure brewing methods tend to have shorter extraction times compared to other brewing methods like drip or immersion brewing. Extraction times for under-pressure brewing can range from approximately 20 seconds for a typical espresso shot to a few minutes for methods like Moka pot or AeroPress. It’s important to follow the recommended guidelines and adjust the extraction time based on your personal preference and the desired strength and flavor profile of the beverage.
Collect
Once the extraction is complete, the brewed coffee, known as espresso, will flow into the cup. If you’re brewing a larger volume, you can continue the process to brew multiple shots.
Serve and Enjoy
Your under-pressure-brewed coffee is now ready to be enjoyed as is or used as the base for other espresso-based beverages like cappuccinos or lattes. Add milk or sweeteners according to your preference.
