The NRP 58mm naked portafilter that included Double-shot filter basket. can hold about 14 – 18 gram coffee. Great for observing your process of making a shot of espresso. Issues such as under- or overdosing, inconsistent or incorrect grind size, uneven tamp pressure, or unevenly distributed grinds, can all cause improper extraction.
The portafilter’s handle is detachable. you can unscrew it when you need to deep clear the filter head (metal parts).
One of the most common visible signs that you’re experiencing extraction issues is through channeling (or spurting), which cannot be seen with a standard spouted portafilter. Exposing the bottom of your portafilter basket will allow you to witness these extraction issues first hand, providing an opportunity to diagnose and improve the quality of your shots.
Channeling and spurting can be very messy, but these are very very common. This is not a defect of the portafilter itself, but instead is your coffee telling you that there’s room for improvement in your preparation process (grind size, tamping, distribution, etc.)
