IMS Big Bang Espresso Filter Basket

The Big Bang pattern features 585 holes concentrated toward the center. This design directs water flow more effectively through the coffee puck, which helps reduce channeling and promotes a more uniform extraction.

Yes, this basket is designed for standard 58mm portafilters, including those on most E61 group head machines. It has an edge-to-edge diameter of 70mm and an internal diameter of 60mm.

For the best results and to ensure an even bed of coffee, we recommend using a 58.5mm tamper. This size provides a tighter fit against the walls of the basket, minimizing side-channeling.

The ridgeless design makes cleaning significantly easier because there is no groove for coffee grounds to get trapped in. You can simply wipe it out or knock out the puck without any residue lingering behind.

The flat bottom provides a stable surface for tamping, which helps keep your coffee bed level. While your dose weight remains the same as your previous basket, you may find that the improved extraction allows you to grind slightly finer to achieve better flavor clarity.
