E61 Bottomless Portafilter with Precision Basket

The E61 Bottomless Portafilter comes equipped with a precise triple insert basket created by IMS. As a training tool, the bottomless portafilter allows for instant feedback and helps identify any channeling that may occur during the extraction process. This is characterized by thin, under-extracted espresso and rapid water passage through fractures in the coffee puck, often leading to the appearance of blond streaks or small holes. Designed to fit most espresso machines with an E61 group, this bottomless portafilter is a valuable asset for any industry expert looking to improve their espresso-making skills.
