Clive Coffee Bottomless Portafilter

A bottomless portafilter is primarily a diagnostic tool. By exposing the bottom of the basket, you can see exactly how your espresso is extracting, which makes it much easier to spot issues like channeling or uneven distribution that you wouldn't notice with a standard spouted portafilter.

This portafilter is available in two specific sizes: 53mm for machines like the La Spaziale A53, and 58mm for standard E61 group heads. Please check your machine's group head size before ordering to ensure a proper fit.

The wood handle is hand-finished and durable, but it should not be submerged in water or put in the dishwasher. Simply wipe it down with a damp cloth after use and apply a food-safe wood oil occasionally to keep the grain looking fresh.

The included triple basket is designed to hold approximately 20 grams of coffee. This larger capacity is ideal for those who prefer a higher dose or want to pull larger shots, though you can use less coffee if you prefer a different ratio.

If your puck preparation is dialed in, it shouldn't be messy at all. However, if you have channeling or uneven distribution, the espresso may spray or drip unpredictably, which is exactly why this tool is so helpful for refining your technique.
