IMS Big Bang precision filter basket 54 mm – h25.5 (for Sage & Breville)
A 54 mm basket built on the Big Bang idea: 585 holes, concentrated towards the centre, that pull your Sage or Breville espresso noticeably sweeter and rounder.
Nobody needs a special basket for good espresso – the original basket does its job. You want one because the cup becomes sweeter and rounder. It's one of many possible choices, and we respect it either way.
What makes this basket special
The Big Bang is IMS's filter basket in 54 mm format for Sage and Breville brew groups: 585 holes concentrated towards the centre of the basket. This spreads the espresso evenly across the whole surface, helps prevent channelling, and brings the coffee's sweetness to the fore while toning down acidity. The basket is ridgeless, built for bottomless portafilters. The medium height of 25.5 mm gives a little more room for coffee. Espresso is extraction by weight ratio, usually 1:2; taste and smell are inseparable, and a large part comes about retronasally. We have observed that the choice of basket fundamentally changes the aroma profile.

Who it's for
For Sage and Breville owners who dose a little higher and want a sweeter, rounder espresso – especially lovely with medium to darker roasts. If you dose lighter or heavier, you'll also find the 54 mm Big Bangs in 23.5 and 27.5 mm. Every budget is welcome.
What goes with it
At its best in the bottomless portafilter of your Sage/Breville. For a level puck: the tamper collection (for 54 mm, a 53.3 mm tamper) – affordable with Normcore, premium with Weber Workshops. Against clumps beforehand: WDT tools. Plus the right grinder. All other baskets: the precision basket collection.
Frequently asked questions
Does the basket fit my Sage or Breville?
Yes – it's made for 54 mm Sage and Breville brew groups, with a 53–53.5 mm tamper. Best in a bottomless portafilter.
What other heights are there?
The 54 mm Big Bang comes in 23.5 mm, 25.5 mm (this version) and 27.5 mm. Taller = more room for coffee; the height is the most reliable indicator of the dose.
Which roasts does the Big Bang suit?
Medium to darker roasts come out especially well. With very light, citrusy coffees, a little experimenting pays off – the Big Bang deliberately tones down acidity.
Can I see the basket before I buy it?
Our showrooms in Bern (Gerberngasse 44) and Zurich (Hagenholzstrasse 50b) show a wide selection, but not our entire range – the display changes. Drop us a quick line at [email protected] before your visit, and we will check whether the product you have in mind is currently there.
Roastery tip
The Big Bang emphasises sweetness and tones down acidity – as if made for full-bodied roasts. From our coffee roastery, Cozy Chocolate, Nutty Delight and – for maximum body without any acidity – Very Nutty work especially well. If you're after the fruity side of light roasts, the Big Bang will give you less of that – we'd rather say so honestly. Our recommendation, one of many.
