material and removable design The filter combines a solid wood handle with a stainless steel filter. The solid wood handle is twistdetachable from the filter, allowing quick inspection and feedback on grind, dosing, and technique for both and experienced baristas. Strong practicality for workflow Split design enables easy maintenance: detach the wooden handle from the filter by twisting. The doublespout portafilter pours two cups at once, so you can brew two individualized espressos simultaneously without cross contamination. Broad compatibility Suitable for E61 series machines, including Rancilio, Bianchi, Vibiemme, BFC, ECM, CBC Royal, La Scala, La Marzocco, SV SAB, Grimac, San Remo, Crem Expobar, Rocket, and Faema. Easy to use for quality checks The E61 doublespout portafilter helps you instantly assess tamping technique. An uneven extraction or coffee biased to one side suggests an incorrect tamping angle, while rogue streams from the spouts indicate the portafilter was not leveled or dosed evenly. Use scenarios Home calibration: test grind size, dosing, and tamp with an E61 machine to dial in your setup. Barista training: demonstrate proper tamping and leveling to a trainee, using realtime feedback from extraction quality. Peakservice efficiency: brew two espressos at once during busy periods, while preventing crosscontamination between shots.
