Superkop Bottomless Portafilter – 58 mm, visible extraction
No bottom to obstruct the view – the espresso flows directly from beneath the basket, first in fine threads, then as a rich, dark stream. You can see exactly whether your puck is extracting evenly.
A bottomless (naked) portafilter for the Superkop hand lever espresso machine, in 58 mm.
What the bottomless portafilter shows
With a bottomless portafilter, the spouts are removed, allowing you to directly see the underside of the basket. If the espresso flows calmly and centrally, the preparation was even; if it squirts out to the side, it indicates channeling. Thus, the bottomless portafilter becomes an honest feedback tool 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 is no right or wrong; ultimately, what matters is that the cup tastes good. Our opinion is one of many.

Frequently Asked Questions
Why a bottomless portafilter?
Because you can see the extraction directly. If the espresso flows centrally and calmly, the preparation was good; side squirting indicates channeling.
Does it fit my Superkop?
Yes, it is made for the Superkop, which works with 58 mm baskets.
Do I need more practice for this?
The bottomless portafilter honestly shows inconsistencies, which is exactly what helps with learning. With a little distribution and even tamping, it will flow nicely in the center.
Can I see it in person before buying?
Absolutely. You can experience it live in our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b). We deliver online within 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 rich chocolate and nutty notes. For maximum body without acidity, try Very Nutty, and for a fruity experience, Wild Peach. This is our recommendation – one of many.
