IMS Precision Filter Basket

This basket is designed specifically for Breville machines that use a 54mm group head, such as the Barista Express, Pro, Touch, and Bambino Plus. It will not fit 58mm commercial-style machines or older Breville models that use different group sizes.

Yes, for the best results, you should use a 53mm or 53.35mm tamper. The standard tamper included with many Breville machines is often slightly undersized, so a precision-fit tamper will help you achieve a more even extraction.

The 583 precisely engineered holes create a more uniform flow of water through the coffee bed compared to stock baskets. This consistency reduces channeling and helps you extract more balanced, nuanced flavors from your beans.

This basket is quite versatile, but it performs best when you dose within that 18-22g range. If you typically dose on the lower end (around 16g), you may find the headspace is too large, which can lead to uneven extraction unless you adjust your grind size accordingly.

The electro-polished finish creates a smoother surface inside the basket, which prevents coffee oils and fines from sticking to the metal. This not only makes the basket easier to clean but also helps the coffee puck knock out cleanly after you pull your shot.
