Bottomless portafilter for Superkop – 58 mm, extraction made visible
No bottom to block the view – the espresso emerges directly 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 you
With a bottomless portafilter, the spout disappears, so you see the underside of the basket directly. If the espresso flows calmly and centred, the prep was even; if it sprays sideways, that points to channelling. That makes the bottomless portafilter an honest source of feedback on 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 forcing anything. There's no right or wrong, what matters in the end is that the cup tastes good. Our opinion is one of many.

Does it fit my Superkop?

Do I need more practice for this?
The bottomless portafilter shows unevenness honestly, and that's exactly what helps you learn. With a bit of distribution and even tamping, it runs nicely centred.

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, Very Nutty; for a fruity experience, Wild Peach. That's our recommendation – one of many.
