58mm Bottomless Portafilter for E61 Machines, Aluminum Alloy
Guaranteed Safe Checkout
A 58mm bottomless portafilter for E61 machinesTake the spouts away and the puck tells you what went wrong.
This 58mm (2.28 in) bottomless portafilter has an aluminum alloy body and fits espresso machines with an E61 style group. With nothing under the basket, you see the shot form and spot channeling the moment it starts. It suits home baristas who dial in by eye, in two colorways: Blue Enchantress and Wizard of Oz.
- Spot channeling as it happens
- 58mm, E61 style group
- Light aluminum alloy body
- Two bold colorways
What changes when the bottom is open
Spouted portafilter
- Coffee runs through spouts before you see it
- A spray or a weak spot stays hidden inside
- You judge the shot by taste after the fact
Bottomless portafilter
- The stream forms right under the basket
- Jets and pale streaks show up in real time
- You correct grind, dose or tamp on the next pull
Expect a few messy shots at first. That spray is the lesson.
What a good shot looks like from below
Watch the bottom of the basket once the pump starts. An even puck forms dark droplets across the whole surface that move to the center and join into one steady stream.
A thin jet shooting out sideways means water has found a crack in the puck. Pale, fast streams usually point to a grind that is too coarse, or to a light dose. Drips from just one edge often mean the tamp was uneven.
Pair it with a precise basket
An open bottom shows more when the basket holes are even. Our titanium 58mm precision basket is one option in the same size.
Check your group before you order
This espresso portafilter is sized at 58mm for the E61 group pattern. If your machine has an E61 head, it matches. Other 58mm groups can place their locking ears differently, so check your group type first. Machines with smaller baskets will not take it.
The details
Before you buy
Will this bottomless portafilter fit my espresso machine?
It will if your machine has a 58mm E61 group. The listing calls the size universal 58mm, but lug positions vary between brands, so confirm your group type first. For a second E61 option, the AIRFLOW 58mm portafilter is built for the same group.
Does a naked portafilter make better espresso?
Not on its own. It shows how the shot extracts, so you can fix grind, dose and tamp.
Why does my shot spray everywhere?
Spraying means water is channeling through a weak spot in the puck. Spread the grounds evenly, tamp level and try a slightly finer grind. A steady spot to rest your tamper helps too, like this walnut tamper holder stand.
Can it go in the dishwasher?
Keep it out. After each session, use mild soap and warm water to clean it manually.
