The Breville Naked Portafilter allows the barista to visually assess how evenly the coffee extracts through the basket. Imperfections in dosing and tamping technique are exposed when the coffee spurts out in different directions instead of straight down into the cup. This is known as channelling. It can be a little messy to start with but is an invaluable learning tool for any espresso aficionado.
This stainless steel 58mm bottomless portafilter is only compatible with the Breville Double Boiler BES900XL Espresso Machine
