What Is A Bottomless Portafilter?

A bottomless portafilter is an important piece of espresso gear that helps in diagnosing and solving espresso extraction issues. With a bottomless portafilter, you will be comfortable while brewing espresso because the spouts are removed, the basket is exposed, and you watch the entire extraction process. This is why bottomless portafilters are often referred to as naked portafilters.

In fact, you will find that quality orientated espresso shop’s barista uses this essential bottomless portafilter.

5 Reasons: Why Does Barista Prefer Bottomless Portafilter

Helps you improve consistency

When it comes to brewing great tasting espresso with your espresso machine, the portafilter will troubleshoot espresso shots instantly and the consistency of coffee served in your espresso bar will increase by leaps and bounds. Thus, you will always get your desired flavor of espresso with perfect extraction.

Produce Delicious Crema 

If you are a serious coffee lover you already know that crema is a flavorful, aromatic, reddish-brown froth that rests on top of a shot of espresso formed when air bubbles combine with fine-ground coffee’s soluble oils. 

The good news is that an experienced barista with fresh espresso beans, a bottomless portafilter will yield 50% or more of Crema because the espresso shot will come in contact with no other surface than the bottom of your portafilter basket. And, no portafilter bottoms and no spouts. 

Another benefit of this portafilter is that the lack of a spout will give you more cup clearance, and allows espresso extraction directly into the cup for serving in most cases. 

Excellent Taste

We all know that more crema means more flavor. Besides this, dirty portafilters are soaked and cleaned, espresso will pass through less metal surface  (i.e. spouts and spout threads) which means less contamination from a dirty portafilter. Furthermore, you will have no hassle on cleaning the bottom of the portafilter basket after each and every shot.

Solves Espresso Extraction Issues

Bottomless portafilters are an important espresso tool that allows the barista to instantly deduce whether the proper tamping technique has been achieved. 

If you find that the extraction leans to one side or the other, chances are high that an improper angle was used when tamping.

On the other hand, if you see rogue streams of espresso coming from the bottom of the basket which means your portafilter was leveled and or dosed unevenly.

Portafilter Diameters

If you use a smaller portafilter instead of a large portafilter, then you have less flexibility over how much coffee you use in it. You can change out the filter basket inside the portafilter to increase the basket depth but you can only add so much depth before the shots start to pull weirdly.

Portafilter diameters are commonly used for different espresso machines

Is a 58mm Portafilter better?

It is crucial that you check the hole size when buying the portafilter because you want precision. 

In fact, Most high-end and commercial machines use a stand size portafilter and basket (58mm) but there is nothing wrong if you use different sizes. For instance, cheaper domestic machines commonly use smaller ones.

Should I tamp my espresso?

If you want the best flavor and perfectly extracted espresso, you’ll need to pack the perfect puck. The best part of a good tamp is that it creates resistance (with evenly compacted coffee) that makes the brewing water work hard to saturate the grounds and extract maximum great coffee flavor. In fact, flat tampers are crucial here. If you have a curved tamper, throw it out and buy a flat one.
