La Marzocco Portafilter "Straight-In" for KB90, Bottomless
Slide in straight instead of twisting, and watch the shot from below: the bottomless straight-in portafilter of the La Marzocco KB90.
In the KB90 spare parts catalogue, La Marzocco lists this portafilter as "Portafilter Naked Straight-In" under A.5.124. Without a bottom or spout, the underside of the basket is exposed. Channeling and uneven distribution show up directly at the basket, not only in the cup.
La Marzocco developed the straight-in system for the KB90: the portafilter is guided into the group in one straight movement, according to La Marzocco for more efficiency and ergonomics at the group head. Our opinion is one of many: we extract by weight ratio, 1:2 as a starting point, and let taste decide.

Frequently asked questions
Which machine is the portafilter for?
La Marzocco lists this straight-in portafilter in the KB90 spare parts catalogue. We have no confirmation of fit for other machines. If you are unsure, write to us at [email protected].
Is a basket included?
No. The portafilter is supplied without a filter basket. You will find baskets in La Marzocco accessories and spare parts.
What is a bottomless portafilter good for?
You see the underside of the basket during the shot. Channeling and uneven distribution become directly visible.
Can I see the product before buying?
Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. Not every accessory is on hand at all times, so write to us beforehand at [email protected].
Tip from the roastery: For watching the shot we roast Cozy Chocolate and Nutty Delight, full-bodied with chocolate and nuts. If you want maximum body without acidity, go for Very Nutty. For the curious: Wild Peach, fruity and lively. That is our recommendation, one of many.
