Bottomless portafilter for Superkop – 58 mm, extraction made visible
No bottom to block the view — the espresso emerges right under the basket, first in fine threads, then as a dense, dark stream, letting you see exactly whether your puck is running evenly.
A bottomless (naked) portafilter for the Superkop lever espresso machine, in 58 mm.
What the bottomless portafilter shows
With the bottomless portafilter, the outlet is gone, so you see the underside of the basket directly. If the espresso flows calmly and centred, the prep was even; if it sprays to the side, that points to channeling. That makes the bottomless portafilter an honest indicator for grind size, distribution and tamping. It fits the Superkop, which works with 58 mm baskets.
Pressure and distribution are learning processes – the bottomless portafilter makes them visible without you having to force anything. There's no right or wrong, in the end what counts is that the cup tastes good. Our opinion is one of many.

Frequently asked questions
Why a bottomless portafilter?
Because you see the extraction directly. If the espresso runs centred and calmly, the prep was good; spraying to the side shows channeling.
Does it fit my Superkop?
Yes, it's made for the Superkop, which works with 58 mm baskets.
Do I need more practice for this?
The bottomless portafilter shows unevenness honestly, and that's exactly what helps with learning. With a bit of distribution and even tamping, it runs nicely centred.
Can I see it in person before buying?
Absolutely. In our showrooms in Bern (Gerberngasse 44) and Zürich (Hagenholzstrasse 50b) you can experience it live. Online, we deliver in 2–4 business days, throughout Switzerland and to Liechtenstein.
Tip from our coffee roastery
Visible extraction is more fun with good coffee. Our Cozy Chocolate and Nutty Delight bring full-bodied chocolate and nutty notes. For maximum body without acidity, the Very Nutty, for a fruity experience, the Wild Peach. That's our recommendation – one of many.
