La Spaziale Bottomless Portafilter (After-Market)
This aftermarket La Spaziale bottomless or naked portafilter will fit most La Spaziale and other 53mm machines (6.0mm fins). Make sure that you measure the fins on your current portafilter to confirm fit. This portafilter will NOT fit Breville machines.
Taste the difference a portafilter can make. The Barista can watch the coffee brew right from the bottom of the filter basket and immediately know if channeling occurs, signaling that a level tamp was not made, which makes this an invaluable tool for training. Most Bottomless Portafilters will accept 21 gram triple baskets since portafilter body depth is no longer an issue. This item comes standard with a 53mm 21 gram triple basket, but will also accept any other 53mm portafilter basket.
