IMS Big Bang Precision Filter Basket 54 mm – h25.5 (for Sage & Breville)
A 54mm basket with the Big Bang idea: 585 holes, concentrated towards the center, which noticeably makes your Sage or Breville espresso sweeter and rounder.
Nobody needs a special basket for good espresso – the original basket does its job. You want it because the cup becomes sweeter and rounder. This is one of many possible decisions, and we respect both directions.
What makes this basket special
The Big Bang is IMS's latest innovation, here in the 54mm format for Sage and Breville brew groups: 585 holes concentrated towards the center of the basket. This distributes the espresso evenly over the entire surface, prevents channeling, and brings out the sweetness of the coffee while reducing acidity. The basket is ridgeless, designed for bottomless portafilters. The medium height of 25.5 mm provides a little more space for coffee grounds. Espresso is extraction based on a weight ratio, usually 1:2; taste and smell are inseparable, a large part of which is retronasal. It is our observation that the choice of basket fundamentally changes the aroma profile.

Who it's for
For Sage and Breville users who want to dose a little higher and desire a sweeter, rounder espresso – especially nice with medium to darker roasts. For those who dose leaner or stronger, the 54mm Big Bangs are also available in 23.5 and 27.5 mm. Every budget is welcome.
What goes with it
Best in the bottomless portafilter of your Sage/Breville. To make the puck even: the tamper collection (for 54mm, a 53.3mm tamper) – affordable with Normcore, premium with Weber Workshops. Against clumps beforehand: WDT Tools. Plus the matching grinder. All other baskets: Precision Baskets Collection.
Frequently Asked Questions
Does this basket fit my Sage or Breville?
Yes – it's made for 54mm Sage and Breville brew groups, with a 53–53.5mm tamper. Best in a bottomless portafilter.
What other heights are available?
The 54mm Big Bang is available in 23.5 mm, 25.5 mm (this variant), and 27.5 mm. Higher = more space for coffee grounds; height is the most reliable indicator for dose.
Which roast is the Big Bang suitable for?
Medium to darker roasts come out particularly well. With very light, citrusy coffees, some experimentation is worthwhile – the Big Bang deliberately reduces acidity.
Can I see the basket before buying?
Yes, in our showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b).
Roaster's Tip
The Big Bang emphasizes sweetness and reduces acidity – perfectly suited for full-bodied roasts. From our coffee roastery, Cozy Chocolate, Nutty Delight, and – for maximum body without any acidity – Very Nutty pair particularly well. Those looking for the fruity side of lighter roasts will find the Big Bang less to their liking – honestly said. Our recommendation, one of many.
