IMS Precision Basket 7–9 g – Single Basket, 58 mm (B70 1T H26,5 E)
A single espresso, made deliberately: 7 to 9 grams, a small, concentrated puck – and a basket that cleanly extracts even this slim dose. In a spouted portafilter, a dense single flows; in a bottomless one, you see it as a fine, calm stream.
Nobody needs a single basket – most people pull doubles. You want it because you enjoy the single as a little ritual of its own and want to hit it precisely. It's one of many possible choices, and we respect it either way.
What Makes This Basket Special
True single baskets are rare – and this one is made for exactly that. The IMS Competition perforation concentrates 253 round holes with a conical cross-section on a small perforated area of 30 mm, matched to the small amount of coffee. This keeps the extraction even at 7–9 g, instead of the water simply shooting through. Made in Italy from AISI 304 stainless steel, with a flat base and a surrounding rim (external ridged) for a secure hold. Espresso is extraction by weight ratio, usually 1:2 – so from 8 g, around 16 g in the cup. Taste and smell are inseparable; much of it happens retronasally. It is our observation that the choice of basket fundamentally changes the aroma profile.

Who It's For
For anyone who deliberately pulls single shots – a small, precise dose, cleanly extracted. Every budget is welcome. It fits both spouted and bottomless portafilters and works particularly well with ECM and other 58 mm E61 machines. You belong here because you love coffee – not because you use a particular basket.
What Goes with It
For the shot: your portafilter (spouted or bottomless). To keep the small puck level: the tamper collection – affordable with Normcore, premium with Weber Workshops. Against clumps beforehand: WDT tools. Plus the right grinder. All other baskets: precision basket collection.
Frequently Asked Questions
How much coffee is this basket for?
For a single shot of 7–9 g (one cup). The small perforated area of 30 mm is matched exactly to this amount.
Will it fit my machine?
It is a ridged 58 mm B70 basket and fits many E61 brew groups – including ECM, La Marzocco, Rocket, Bezzera, Rancilio, Faema, Victoria Arduino. Suitable for spouted and bottomless portafilters.
Spouted or bottomless?
Both. In a spouted portafilter, you pull a classic single; in a bottomless one, you see the extraction directly.
Can I see the basket before buying?
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
Even a single thrives on dense, aromatic beans. From our coffee roastery, Cozy Chocolate and Nutty Delight pull through full-bodied and round. If you're looking for maximum body without any acidity, stick with Very Nutty; if you like it fruity, discover a lively peach note with Wild Peach. Our recommendation – one of many.
