Gaggia created the pressurized basket so you can have the best of both worlds and use either format without having to buy a full portafilter, or separate machine.
Just pop the basket out and swap the other basket in. Product expert, writer, and occasional YouTube presenter, Nick has a decade of specialty coffee experience and a passion for equipment.

Support Wiki Don't know what part you need? These are able to be clicked in and out of the portafilter for cleaning, as well as changing of sizes. Portafilters are designed with a mesh at the base. This is punched out of the metal to form a barrier with holes small enough that you will not allow coffee grounds to pass through it, while being large enough to let the water flow through. The mesh is designed thoroughly to ensure consistency between all of the shots that are pulled as well as to ensure an even extraction and flow of liquid through the coffee.
Pressurised Baskets sometimes referred to as double wall baskets consist of a standard mesh base followed by another 'wall' which has generally one small hole in which the extraction is forced through.
This creates a greater level of pressure within the basket when brewing occurs. Commonly pressurised baskets can be found with most entry-level home espresso machines and may be provided with higher end home espresso machines. However they would not be used in a commercial setting. Espresso is a great example of what happens when people experiment with food, looking for new ways to tinker with the process and create new and interesting foods.

Richard Baguley , Colin McDonald. April 6, a. The espresso machine First developed in the late 19th and early 20th century, the espresso machine looks quite different from the drip coffee maker. I also quite enjoy the process of preparing coffee with the non-pressurized filter basket.
Ever since I got the hang of it I have impressed quite a few of my friends with my espresso-making skills. You will get consistent results with the coffee, even if the level of tamping, the coffee grind, and the dose differ between each brew. You may decide that the battle of the pressurized versus the non-pressurized one is won by the double-wall filter basket. However, in time you might want to dive deeper into the world of coffee and upgrade to a higher-end grinder and a single wall filter.
I plan on writing an article to give you a detailed guide on how to use the non-pressurized portafilter to ease your journey as a beginner.
Hi there! Such an excellent approach to this topic! Definetly worth it based on your post. The whole purpose for pressurized baskets is so you can use ground coffee off the shelf from the supermarket, which allows you a wider selection of coffees. Because supermarkets stock more ground coffee than whole beans. Additionally, if you enjoy lattes, then crema content is not as important.
