IMS Baristapro Nanotech Precision Basket – Ridgeless, 22g (58mm)
Twenty-two grams, packed into the basket: a generous dose for those who like their espresso dense and intense. The puck sits high, and in the naked portafilter, the fast, even flow of the Nanotech basket tames the large amount, preventing uneven extraction. After knocking it out, the basket comes out almost clean – oils and water bead off the Nanotech quartz coating.
Nobody needs a precision basket to pull good espresso – the original basket does its job. You want it because the cup becomes denser, rounder, and clearer. This is one of many possible decisions, and we respect both directions.
Important: The Shot Runs Significantly Faster
A note from our experience that you should know before your first shot: The Nanotech quartz coating noticeably reduces friction in the basket – the water flows significantly faster through the puck. This shifts the extraction dynamics, and the taste often changes radically compared to your previous basket. This is not a flaw, but the essence of this basket. Especially with the high 22g dose, you should definitely expect to grind finer and re-tune your recipe – grind size first, then dose if necessary. Our opinion is one of many – but you should factor in this effect.
What Makes This Basket Special
Espresso is extraction via a weight ratio – usually 1:2, meaning about 44g in the cup from 22g of coffee. How cleanly this succeeds depends on how evenly the water flows through the puck. A precise, even hole pattern distributes the flow across the entire surface – fewer channels, less over- and underextracted areas simultaneously. With a high dose like 22g, this consistency is crucial: a lot of coffee that is still extracted smoothly and controllably. What you taste is density, sweetness, and a long finish; caramel, chocolate, and nuttiness are prominent. Taste and smell are inseparable – a large part of the aroma is created retronasally, when swallowing. The Nanotech quartz coating on the AISI 304 stainless steel makes the surface smoother, repels oils, and facilitates cleaning. It is our observation that basket choice fundamentally changes the aroma profile.

Who It's For
For everyone who loves dense, intense espresso and doses high – with a basket that consistently handles the large quantity. Every budget is welcome, and in the naked portafilter, the difference becomes directly visible. If you prefer a more moderate dose, the same basket is available in 15, 18, and 20g. You belong here because you love coffee – not because you use a specific basket.
What Goes With It
The basket shows its best in a naked portafilter. Because the shot runs faster, a finely adjustable grinder is particularly worthwhile. To make the puck level: the tamper collection – affordable with Normcore, premium with Weber Workshops. Against clumps before: WDT Tools. On top of the puck: Puck Screens. All other baskets: Precision Baskets Collection.
Frequently Asked Questions
Why does my shot run faster with the Nanotech basket – and what do I do?
The Nanotech quartz coating reduces friction in the basket, causing water to flow faster through the puck. Extraction shifts noticeably and the taste often changes significantly. Therefore, grind finer and re-tune your recipe – grind size first, then dose.
Is 22g too much for my portafilter?
22g is a high dose; ensure sufficient headspace to the shower screen so the puck doesn't hit it. This usually fits well in most 58mm portafilters. If you prefer a more moderate dose, take 18 or 20g – the same basket is available in all sizes.
What does "ridgeless" mean?
The basket has no circumferential retaining ridge and is held by the spring or the portafilter. It fits without problems in most 58mm portafilters – if in doubt, tell us your portafilter model.
How do I clean the basket?
Daily backflush without cleaner, every approximately 50 shots with cleaning agent like Urnex Cafiza. Thanks to the coating, less coffee oil adheres.
Can I see the basket before buying?
Yes, at our showrooms in Bern (Gerberngasse 44) and Zurich Oerlikon (Hagenholzstrasse 50b).
Roastery Tip
A high dose and a consistent basket particularly reward dense, aromatic beans. From our coffee roastery, Cozy Chocolate and Nutty Delight brew with a full body and roundness. Those seeking maximum body without any acidity can stick with Very Nutty; those who like it fruity can discover a vibrant peach note with Wild Peach. Our recommendation – one of many.
