Description

Optimized for Medium to Light Roasts
This filter basket is specially designed to enhance extraction with medium to light roast coffees. The closer spacing of the holes supports a finer grind, allowing for improved water flow and higher extraction yields. The result is a fuller body, richer crema, and more pronounced sweetness with bright, ripe fruit notes.

M-Type Hole Pattern for High Extraction
IMS’s proprietary "M" hole pattern features a concentrated layout engineered for even water dispersion. This design promotes homogeneity in flavor, helping you achieve a full-bodied espresso with exceptional crema and clarity.

Thoughtful Internal Shape
The basket features a rounded internal corner, creating a smooth transition between the walls and base. This eliminates dead zones during extraction by directing water more evenly across the coffee bed - especially important for consistent saturation and balanced flavor development.

Easy to Clean, Built to Perform
The seamless, polished interior prevents coffee grounds from sticking in corners, making cleaning quick and efficient. This not only extends the lifespan of the basket but also helps maintain shot consistency over time.

Compatibility Note
To fit this basket into your stock portafilter, the plastic insert at the bottom of the portafilter must be removed.
