What is a Bottomless Portafilter & What's it Used For?

Bottomless portafilters are used as a training tool. It will provide you with immediate feedback and can see if "channeling" occurs right away. Channeling is the rapid passage of water through fractures in the coffee puck, which produces a thinner, under-extracted espresso. When it occurs, you'll often see sudden appearances of blond streaks in the stream of espresso; sometimes the puck will even have pencil lead-sized holes where channeling occurred.

The Rancilio Erogonomic Bottomless Portafilter fits all of the Rancilio commercial machines, the Silvia, as well as other E61 group machines.
