Ascaso 57mm Bottomless Portafilter (OEM)

This OEM bottomless or naked portafilter will fit 57mm Ascaso machines (Dream Zero, Arc, Basic and others).  

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 57mm 14 gram double basket, but will also accept other 57mm portafilter basket.  

Still not convinced that you should own a bottomless portafilter?  Have a look at this great article by Perfect Daily Grind.
