Wiedemann precision funnel 41 mm for Eureka New Mignon.
This version is made for the Eureka New Mignon. For other grinders there is the Precision funnel 41 mm for other grinders. As with all 41 precision funnels, according to Wiedemann it fits exclusively on the La Marzocco 7-g basket (Strada) and is used together with the Precision tamper 41.
Wiedemann precision funnel 41 mm: High-end funnel for true 7g single shots
The Wiedemann precision funnel 41 mm is not a classic dosing ring or funnel but a highly precise specialist tool for a clearly defined workflow: perfect single shots with 7g precision baskets.
If you want maximum control, clean dosing and reproducible results, this precision funnel is a game changer. If, on the other hand, you are looking for a classic dosing ring for 58mm or 54mm, this product is deliberately not the right choice.
What is the 41 mm precision funnel really?
The 41 mm precision funnel was developed specifically for the La Marzocco X-Filter (7g single shot basket). This basket has an inner extraction area of only 41 mm – significantly smaller than classic 58 mm baskets.
The funnel performs two decisive functions:
- Precise dosing: The ground coffee is guided exactly into the 41 mm extraction area
- Tamper guidance: The matching 41 mm tamper is guided with exact centering
Without this precision funnel, part of the coffee grounds ends up outside the relevant area – which leads to inconsistent extraction.
Why this system is unique
- Perfect for true 7g single shots (not a halved double shot)
- Maximum precision for distribution & tamping
- Clean workflow without coffee loss
- Ideal for home baristas, R&D and sensory work
- Compatible with WDT technique (Weiss Distribution Technique)
The result: clean extraction, reproducible results and significantly less coffee consumption.
Important: Not a classic dosing ring / funnel
The biggest mistake: Many people confuse the 41 mm precision funnel with a normal funnel or dosing ring.
That is wrong.
- ❌ Not a universal funnel for 58 mm baskets
- ❌ Not compatible with 54 mm portafilters
- ❌ Not a replacement for classic dosing rings
The 41 mm refers to the inner working area – not the portafilter.
The big topic: GBW grinders (Grind-by-Weight)
Many modern grinders such as:
- Eureka Mignon Libra
- Mahlkönig E65 GBW
- Fiorenzato AllGround Sense
work with an integrated scale and dosing fork.
Problem:
- A precision funnel or funnel protrudes beyond the portafilter
- The portafilter no longer fits into the holder
- Hands-free GBW no longer works
This means:
- The funnel can only be used manually held
- The advantage of the GBW grinder is lost
Conclusion: For GBW grinders a classic 58 mm dosing ring is the better solution.
Compatibility – at a glance
Best suited
- 58 mm portafilters (E61 standard)
- La Marzocco Linea Mini / GS3
- ECM, Profitec, Rocket
- Single Dose Grinder (Niche Zero, Fellow Opus)
- Classic grinders without GBW
Limited suitability
- GBW grinders (usable only manually)
- Mahlkönig E65 GBW
- Eureka Libra
- Fiorenzato Sense
Not compatible
- 54 mm portafilters (Sage, Breville, Olympia Maximatic)
- 49 mm systems (La Pavoni)
- Standard 58 mm baskets without a 7g system
Reason: The funnel would fall into smaller baskets instead of sitting on them.
Buying recommendation
The precision funnel only makes sense as part of a system:
- 7g precision basket (La Marzocco X-Filter / VST / IMS)
- 41 mm precision tamper
- 58 mm portafilter
Without this combination the product does not function usefully.
Who is this product perfect for?
- Home baristas focused on precision
- Espresso enthusiasts with a 58 mm setup
- Single shot lovers (7g instead of 18g)
- Coffee comparison & sensory testing (R&D)
- Caffeine-conscious users
Who is it the wrong choice for?
- Users of GBW grinders in hands-free operation
- Owners of 54 mm machines (Sage, Olympia)
- Customers who are only looking for a simple funnel
- Standard espresso users without a 7g system
Technical details
- Inner diameter: 41.2 mm
- Height: approx. 13 mm
- Material: aluminium / precision manufacturing
- Suitable for: 7g X-Filter systems
- Mounting: mechanical seat (no magnets)
Conclusion
The Wiedemann precision funnel 41 mm is not an accessory for everyone but a high-end tool for maximum precision.
If you deliberately set up your equipment for single shot perfection you will get one of the best tools on the market here.
If, however, you are looking for a classic funnel or dosing ring – choose a 58 mm or 54 mm model instead.
