Clive Coffee Bottomless Portafilter

A bottomless portafilter is primarily a diagnostic tool. By exposing the bottom of the basket, it allows you to see the extraction in real-time, making it easy to spot issues like channeling or uneven distribution that you wouldn't notice with a standard spouted portafilter.

This portafilter is available in two sizes: 53mm for machines like the La Spaziale A53, and 58mm for standard E61 group heads, including brands like LUCCA, Profitec, ECM, Lelit, Quick Mill, and Rocket. Please verify your machine's group head size before ordering.

Yes, it includes a high-capacity triple basket designed to hold a 20-gram dose. This allows you to pull larger shots, though you can also use your own precision baskets if they are compatible with the portafilter's diameter.

The wood handle is durable and finished for daily use, but it should not be submerged in water or put in the dishwasher. Simply wipe the handle clean with a damp cloth and dry it immediately to keep the wood in good condition.

If your puck preparation is uneven, a bottomless portafilter can cause espresso to spray or drip outside the cup. While this can be messy at first, it is the best way to learn how to improve your distribution and tamping technique for a cleaner, more consistent shot.
