  • Why use a bottomless portafilter?

    Bottomless portafilters are used as a training tool and are essential in maintaining the quality of espresso. Rocket 58mm naked portafilter allow the barista to see how the espresso is dripping from the machine. It will provide you with immediate feedback and can see if channeling occurs right away.


    Blonding is an unfortunate side effect of under-extraction, and causes the espresso to taste weak. Channeling can be detected when the espresso is dripping in multiple streams or at uneven angles. Baristas are able to prevent these problems by using the appropriate espresso extraction portafilter.
