E61 Bottomless Portafilter with 21g Precision Basket
This E61 bottomless portafilter with a micro-fine 21 gram triple insert basket allows for you to see if channeling is occurring during your espresso extraction. Channeling results in a thin, under-extracted espresso due to an incorrect coffee grind or an inconsistent or level tamp.
Channeling is the rapid passage of water through fractures in the coffee puck, and if occurring, you'll often see appearances of blond streaks in the stream of espresso, and the puck will often have pencil lead-sized holes where channeling has occurred.
A great training tool, and this bottomless portafilter fits most E61 group espresso machines.
