See What’s Ruining Your Shot Standard portafilters hide what’s really happening during extraction. A bottomless portafilter lets you see everything. Channeling, uneven flow, and puck prep mistakes become obvious, so you can fix them fast and pull better shots. And when everything is dialed in, you get to watch those clean, syrupy extractions flow exactly the way they should. *See our Product Compatibility Guide for a complete list of product / machine sizing and compatibility. PLEASE NOTE: Channeling and spurting can be very messy, but are EXTREMELY 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.).
