A bottomless Portafilter is a crucial tool for diagnosing espresso extraction issues and has become an essential addition to any quality-orientated espresso shop’s barista tools. It allows baristas to watch the entire process from start to finish with an exposed basket that can be lowered down into place or raised out of sight when not in use – The Bottomless Portafilter is sometimes referred to as a Naked Portafilter!


PLEASE NOTE: To optimize your espresso extraction, you must first understand that channeling and spurting can be rough. It is not a fault with the portafilter itself, but rather it’s telling us there needs improvement in the preparation process (grind size/ tamp level)

Benefits of Bottomless Portafilter 

There is nothing better than a bottomless portafilter to transform your espresso game. Some of the benefits of a bottomless portafilter are as follows:

  1. It is an essential piece of equipment.
  2. It is a crucial tool for diagnosing espresso extraction issues.
  3. It allows you to watch the entire extraction process.
  4. It aids in diagnosing espresso extraction issues.

Bottomless (Naked) Portafilters are an excellent way to make sure your espresso shots taste perfect! These machines have no filter, so you know they’ll be pure. This bottomless portafilter or naked one fits onto any device with a 58mm tamper size – which means it will work with all major brands of high-end commercial coffee makers too!.

Bottomless Portafilter Vs. Regular: Design Difference

The difference between a bottomless portafilter and a regular, aka spouted portafilter, is that the espresso does not go directly into the cup in the spouted portafilter. The espresso first drips on the bottom of the spouted portafilter and then passes through single or double spouts.

As its name implies, a bottomless portafilter has neither spout nor bottom. The great advantage of a bottomless portafilter is that you can see the espresso as it drips from the basket screen into your cup or glass after attaching it to the machine. Sometimes we call it a “naked” portafilter because it shows everything that a regular portafilter hides.

Which Should You Buy: Bottomless or Spouted Portafilter

If you are a regular barista and offer coffee to your customers at the coffee shop, you should use a double-spout portafilter.

Because if you have a lot of clients waiting in line and you think this rush of customers is not going to end, then using two spouts can be very helpful for you, as you can take two shots simultaneously.

Conversely, if you are making espresso at home, a bottomless portafilter will work fine. Using a bottomless portafilter, you can see everything going on with espresso, thus comparing your barista skills well.

5 Reasons To Use A Bottomless Portafilter


Naked portafilter has become a valuable tool for espresso training. It is a must-have for any trainy, and experienced baristas benefit greatly. You can quickly determine whether your grinding size is right or wrong and whether you are using the proper diet and technique to fill the basket. Valuable signals from a bottomless portafilter tell a trainee where things are going wrong, and a correction may be needed.


Using a bottomless portafilter will increase your ability to resolve espresso shots quickly. If you own an espresso bar, the consistency of the coffee served in your bar will exceed in no time, giving your espresso bar a clear and essential advantage over other espresso bars.


Whether you are an experienced barista or an avid espresso maker at home, I bet that if you have the best and freshest coffee beans to make espresso and you are using a bottomless portafilter, with this experience, you will get 50% or more of crema over the top of your espresso cup. Do you know why? The simple answer is that when your espresso shot doesn’t come in contact with anything other than the bottom of your portafilter basket, it will offer a naked view for you to see. Because there are no portafilter bottoms and no spouts under the portafilter you are using, it retains the tiny crema bubbles we’re all looking for in a perfect espresso. And these bubbles remain intact without any damage. Furthermore, when the espresso falls into the direct cup without contact with anything other, it will provide the user with a better cup clearance and give more beauty to the cup.


I think there are two reasons why the taste is so excellent: First, a bottomless portafilter adds cleanliness to your espresso brewing process, as it allows the user to clean the lower compartment of the portafilter after each shot. Second, your espresso shot rarely hits metal when using a bottomless portafilter. Because your drink will hit the metal less, it will be just as delicious, and this portafilter has no bottom. I think you must have understood!

Espresso Extraction Troubleshooting

When you use the bottomless portafilter, you see all the stages of espresso brewing with your naked eyes to immediately see if the proper tamping technique has been obtained. If the extraction is tilted to one side or the other, it is clear that you may have used the wrong angle when tamping. If you see rogue streams of espresso dripping from the bottom of the portafilter compartment, you have unevenly leveled the portafilter.

Drawbacks of a Bottomless Portafilter: How to Use It? 

Each Bottomless Portafilter has a couple of drawbacks. The first drawback is the price. But as for its price, this little gadget will set you back a hundred bucks. And if you already have a fancy espresso machine and grinder, it might be a relatively small cost. Its second drawback is the rim. Because the edge around the bottom of the portafilter is sharp enough to cut you, you’ll want to be careful when cleaning.

Bottomless Portafilter Vs. Spouted Portafilter

Taking aside its drawbacks, I get that much more satisfaction when I put my old spouted portafilter away and use the Bottomless Portafilter exclusively. And it also takes a little extra care and sometimes a little extra cleanup if I compare it with my old spouted portafilter. Above all things, I get much more satisfaction when I pull an excellent shot of espresso.

Should You Buy A Bottomless Portafilter?

As for considered coffee drinkers, there are two kinds of espresso lovers. The first kind of those who want a low-maintenance, one-touch solution are fond of Nespresso, Keurig, Tassimo, Dolce Gusto, or other single-serve brewing systems. And the second kind is those who geek out, dabbling with all the little nuances it takes to pull the perfect shot. The second coffee lovers prefer a bean-to-cup coffee machine with an integrated grinder or a separate grinder because they like to grind their coffee beans. The Bottomless Portafilter is your get-to-go if you fall into the latter category.
