Portafilters are essential in maintaining the quality of espresso. Bottomless (naked) portafilters, such as the Rocket 58mm naked portafilter allow the barista to see how the espresso is dripping from the machine.
This means they will be able to ensure the espresso does not experience blonding or channeling. 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.
The Rocket bottomless portafilter and barista tool is one of the best products for espresso extraction. It offers a great view of the espresso stream so baristas can easily detect and prevent problems to ensure the perfect cappuccino or latte every time.
