FAQs
Why should I switch to a bottomless (naked) portafilter?
A bottomless portafilter is the ultimate diagnostic tool. It allows you to see the extraction process directly, helping you identify channeling or uneven tamping in real-time. Plus, it creates a thicker, richer crema by eliminating contact with the spouts.
What material is the handle and head made of?
The head is CNC-machined from high-grade 304 stainless steel for maximum durability and heat retention. The handle is crafted from premium, high-density materials (available in Walnut or sleek Black) to ensure an ergonomic, non-slip grip during heavy daily use.
Which espresso machines is this portafilter compatible with?
We offer multiple versions to fit the world’s most popular machines. Please choose the correct size for your setup:
54mm: Perfect for Breville / Sage 8-series machines (Bambino, Barista Express, etc.).
58mm: Industry standard for E61 group heads and professional machines (Rocket, Lelit, Flair 58, etc.)
Does it include a filter basket?
Yes! Our portafilter comes with a high-flow, precision-drilled non-pressurized filter basket. This ensures maximum clarity and flavor extraction, especially when paired with a high-quality grinder.
Is it easy to clean?
Absolutely. Since there are no internal spouts or nooks where coffee oils can build up, a simple rinse under hot water is usually enough. The handle is also detachable for deep cleaning of the stainless steel head.
