IMS Big Bang Espresso Filter Basket

This basket is designed for 58mm E61 group heads, which covers a wide range of professional and prosumer machines. If your machine uses a standard 58mm portafilter, it should fit, but you should verify your specific machine's compatibility before purchasing.

The hole pattern is concentrated toward the center to guide water flow more effectively through the coffee puck. This design helps minimize channeling and promotes a more even extraction, which typically results in a cleaner, more balanced cup.

The ridgeless design is primarily for maintenance and workflow. Without the groove found in ridged baskets, it is much easier to knock out your spent coffee puck and wipe the basket clean, ensuring no old grounds get trapped.

Because this is a standard 58mm basket, a 58mm or 58.5mm tamper will work. A 58.5mm tamper is generally recommended for precision baskets to ensure a tighter fit and better coverage across the entire surface of the coffee bed.

Yes, precision baskets like this one often require a slightly different grind setting than stock baskets. Because the extraction is more efficient, you may find you need to adjust your grind size—usually slightly finer—to dial in your shot perfectly.
