Bottomless portafilter

A bottomless portafilter, also known as a naked portafilter, is a special filter carrier used for espresso machines.

Unlike a traditional portafilter, a bottomless portafilter has no base plate or manifold, exposing the view of the coffee spout.

Are there any advantages?

The advantage of a bottomless portafilter is that you can watch the entire extraction process of the espresso.

Since there is no bottom, you can see the coffee flowing directly out of the filter. This makes it easy to spot problems such as uneven extraction, channelling (where the coffee flows through the grounds in undesirable areas) or other faults.

Gimmick or not?

A Bottomless Portafilter is often used by professional baristas and coffee lovers to improve their espresso technique and monitor the quality of the extraction process.

However, it also requires some skill and experience, as even grinding, distribution of the ground coffee and correct tampering are necessary to achieve optimal extraction. If this is not the case, the coffee will splash in all directions during extraction.

What to look out for

It is important to note that not all espresso machines are compatible with a Bottomless Portafilter.

The portafilter must be designed and manufactured specifically for the machine in question. Therefore, before buying, you should make sure that the portafilter fits your espresso machine.
