Why Choose a Bottomless Portafilter?

The bottomless design allows for a full view of the espresso extraction process, helping you achieve greater consistency in your shots. Plus, it enhances the crema yield by 50% since there's no extra contact with metal surfaces, preserving the integrity of the crema.

Please Note

Switching to a new portafilter may require adjustments to your grind size, dose, or tamping technique. It’s common to see spurting or channeling at first — this isn’t a defect, but rather a valuable way to spot areas for improvement. With a few tweaks, you'll be pulling smoother, more consistent shots in no time.
