Gorilla Gear burrs in a Niche Zero

Just out of curiosity, is there any difference in total weight of the burr set between the standard and these? And if there is, can that have a negative impact on longevity, or any other aspect of the grinder/motor?

That’s a good question

DrForinor Just out of curiosity, is there any difference in total weight of the burr set between the standard and these? And if there is, can that have a negative impact on longevity, or any other aspect of the grinder/motor?

Isn’t the motor more likely to suffer due to a more aggressive cut/more load on the motor?

Only the weight of the cone would be relevant all else being equal, but I don’t have any idea on the relative weights of suitable burr materials.

DrForinor I’d be surprised if the weights were substantially different (more than 5%). The overall volume is the same (diameter and height), the material is basically the same (steel - the weight of any coating will be negligible vs. the metal weight), and the only differences are in the profile of the burr edges themselves, which can’t be all that much different as they still need to grind the same size and hardness coffee beans.

Yeah people were talking of stalling

Imo it’s a great way to ruin your warranty 😂

MWJB Isn’t the motor more likely to suffer due to a more aggressive cut/more load on the motor?

Would it actually suffer? If the burrs are more aggressive in their cutting abilities, doesn’t that mean the motor has an easier life since the burrs are cutting “better” ?

CoyoteOldMan That does make sense.

Cuprajake Honouring your warranty obviously does play a part huh!

Well if you change part of the product then I wouldn’t warranty it.

Like when you remap a car and the turbo blows then try to claim manufacturer fault ..

Niche are not commercial machines, there finely designed consumer products,

Chuck these burrs in a mazzer kony no issues the motor can take it, the niche it could destroy the gearbox inside, or trash the motor brushes.

Just not so sure it’s a great move,

If the worst happens I don’t even know if you can buy spare parts for the niche.

Cuprajake There were 2 burrs tested in the prototype Zero, A & B, similar grind performance but A consumed less power to grind & B failed punishment testing and failed to grind very fine grinds with hard, light beans.

CoyoteOldMan What is the difference in weight of the Ditting 55mm steel burrs, vs the 55mm ceramic burrs in the Vario/Forte grinders? 😀

Nevertheless, given similar base materials (I don’t think many grinder burrs are made from aluminium & none from lead, or uranium), I agree that burr weight may not be the most significant difference.

Why do they need to produce grinds of the same size? All brew methods have a range in useable grind size. Grinders are usually adjustable, you can vary the burr gap with different burrs to reach an equivalent ‘size’ (here, by “size” I mean a normalised extraction at the same brew parameters, rather than an identical average size and/or distribution). Grinders make very varied grind distributions, but these very large measured differences are not intuitively, nor linearly related to quality. They are absolutely not constant, nor close to. They are repeatable (e.g. the same grinder grinds to a repeatable distribution, but this may not match other grinders).

‘Grind size’, as a concept, is not intuitive either, two grinds of the same average size (d50) can have very different distributions and another indicator (d10, or d16) may be a better predictor of extraction for a given method. In the old CBI research, they did specify average size, but they had also established a known/expected distribution characteristic.

I have seen blade grinders with a smaller std.dev in grind distribution than some burr grinders.

Fellow originally warned people off changing burrs, especially to SSP, then changed their stock burr and then offered SSP as an OEM option. In short, they obviously screwed up the original design.

The Kony burrs were specifically chosen to consume the right amount of power and not cause problems. Anything else may not give optimum performance, as the characteristics of the burr could be unsuitable..

MWJB I have no idea how much the Ditting or the Vario burrs weigh. What I do know is that the current conversation started from a question on the weight of the Gorilla Gear burrs for the Niche, which are (supposedly) “nanodiamond” coated steel. The standard Mazzer burrs are made of steel, not ceramic. Based on this, I doubt that they are very different in weight.

I also didn’t say that they produce grinds of the same size or distribution. What I did say is that the amount of metal removed from the blank won’t be that different, as they need to grab the same coffee beans and produce ground particles of roughly the same size, i.e. within a fairly narrow set of dimensions when compared with the macroscopic size of the burrs (40/63 mm vs. ~0.05 to 1 mm). The adjustability of the grinder does not change the weight of the burrs, and obtaining a different distribution of particle size doesn’t necessarily change it either, while the quality or repeatability of the resulting coffee are neither here nor there.

The adjustability of the grinder does not change the weight of the burrs but it does allow burrs of similar size/weight/volume (or dissimilar) to produce useable/comparable grinds. The repeatability of the grind is inbuilt to the burrs & grinder design. If it was not repeatable for that grinder, you wouldn’t be able to dial in any grinder,
