It looks like Niche have released a new grinder - The Best Flat Burr Coffee Grinder - The Niche Duo

On first glance, it appears to be just like the Zero but with 83mm flat burrs. It also seems to come with 2x burr sets, each set optomized for espresso and filter. This could be an excellent prospect for many. Priced at £799.

I can’t believe this has come up today. I was about the pull the trigger on a Niche Zero after umm’ing and ahh’ing over that, the DF64 and the Eurka Oro because of the flat burrs. Then, this comes out and throws all my plans out the window.
Is it worth £300 more, hmmmmm?

Hi folks,
My very first post here!
I've just bought a Lelit Elizabeth and have been looking at a new grinder. I was on the Niche site only a couple of hours ago looking at the Niche Zero and noticed this Duo but had no idea until now that it was a brand new product.

Do you think it's really going to be worth the increase in price for the flat burr?
I'm keeping my eye out for a second hand Niche Zero. I've read a few reports that the customer service from Niche is quite poor?

almost the same situation as you. I was looking at a zero to accompany an Elizabeth that I’ll be purchasing soon. Also wondering if it’s worth the extra over the zero :/

Niche cs is bang on,

What coffee do you drink, if it's medium and lighter the flat 83mm burr will do it more justice, I have them in my major.

If you like darker stuff then while good the 83mm may be lost on you, and the zero a better option.

Both will be good either way
Medium roast usually for espresso. The odd lighter roast and absolutely no dark roasts.
I’m coming from a Barista Express so I’d kinda hope the Niche Zero would be enough of a step up for me to notice. The 83mm might be lost on me, or so I’m telling myself…

I've been spoilt, I have had both the stock 83mazzer burrs and the SSP, the zero makes great espresso,

But for me it feels more blended, more rounded where the flats allow you to pick out more individual notes, just a tad more clarity. The SSP take this further with more brightness.

Don't forget were talking subtleties, don't sweat it, work to your budget

I'm sure the duo would sell on quick 🤣

I'd like to see RPM and power levels in the details. Personally I haven't had any light roast problems with conical. I do adjust ratios to get the taste a bean should have what ever roast it is.

Interesting price for that burr size. Competitive as is the other version really.

Offering with 2 sets of burrs though? Make can influence price.

Not me.

But it’s a great prospect and I think has the potential to shake the grinder market a little in this sector - it’s a great time for us as consummers as things develop between manufacturers and things become more competitive.

I can only imagine that all other aspects of the grinder are right in line with what the Niche Zero brings.. I may try in future!

Niche duo review

Hi all,

Finally I can speak about the niche duo, its been hard work watching the speculation over whether niche would go flat burr

I was asked in November to be a tester of a new product, I had no idea what it was till I said yes, after some email exchange I get a shipping email and then a box turns up, it was a niche.

The box turned up just as a new niche zero would, fully packed as if it had be bought from the website, box opened and grinder unpacked, it was placed on my counter next to my other grinders:
The other grinders are a niche zero and a mazzer major with both stock and ssp hu burr sets

All way through I’ve taken notes as its good to go back, this was my initial thought upon unboxing, well boxed, good size, smaller than the mazzer, zero point looked good.

I spent a few days getting to grips with the grind settings, though already owning a zero the duo is second nature.
Early observations, I did some initial testing,
Work flow both the zero and duo you add beans, close the lid and grind, with the mazzer you wdt, dose, brush then give the motor another blip to clean the grinds, this led onto the next test retention and exchange.

On a clean grinder, with a 20g dose going in my major gave 19.3g out, the next 3 tests with 20g in I got 19.8,20g,19.7g out, as the zero is known I didn’t test that, the duo clean took 20g in also gave out 19.3g, and the following 20g in produced 20g, 20.1g, 20g. grind times very similar between the stock major burrs and the duo, but the ssp ground in half the time.
After a week of dual use, I cleaned both grinders to see what was left inside. The mazzer with the ssp fitted retained 2.2g and the duo 1.2g,
I did a sound test using a very simple phone app, the major 70db, zero 64db, duo 69db.
Then after that it was just a case of use it, I find for my use, med to med light and even filter roasts on my test grinder I have about a 5 step window for dialling in, this seems to equate to what the mazzer does also, I did some experimenting with the same bean, same dose and shot times and

didn’t tell the test subject (mrs) and both times she preferred the duo to the ssp burrs, this was a medium bean in milk.
More weeks past, and I took the ssp out of the major and added the stock mazzer burrs, which is what’s inside the duo, to give it a grinder to grinder test rather than burr to burr, the first thing I noticed was the oe burrs in the major were now out of alignment, I had shimmed the ssp, so I had to re shim and marker test the major, to get it some what parallel, the duo out the box marker tested perfect, in this time, multiple cleans between the duo and the zero saw them both hold less than 1g retention, just a note on calibration the duo comes calibrated from factory, so cleaning doesn’t affect the zero point.
The burrs come on their own carriers, they are designed not to be swapped out for other burrs, they are designed for mazzer burrs only,
Some time round January I noticed the static really dying off and the cup on the duo becoming a lot cleaner dose for dose, this is with no wdt at all.
The big thing with the duo is the ability to remove the burrs and add the second set of filter burrs, visually different to the espresso burrs and also taste as well, its so quick to change, one bolt, remove both burrs, clean and install the burr of choice, no need to calibrate, just go to your setting, I found mid to early 30’s good for a v60 with an Ethiopian filter roast. I don’t drink much in the way of filter now, but there was a noticeable difference to the conical in the zero.

Evaluation.
I took the major off my counter about 2 months ago, the duo offers a smaller size, ease of use and a huge burr set, comparing the duo to the ssp it gives a more rounded balanced cup, the ssp pull to the brighter more acidic side, while adding some sweetness it can unbalance the cup, they certainly give for a worse visual shot, breaking down and looking thin, they also pass on more fines to the cup, were as the duo burrs give a very even pour, bringing out the balanced character of the bean, if its light and tea like you get that, if its richer and more body that comes through also,

Its been amazing to have been asked to be part of this trial, and I’ve had a good 6months with the niche duo, ill be sad to see it go.

Thanks jake

Copy and paste any questions just ask

A gearbox as in the grinder can change gear as it’s grinding? Sorry that might be a ridiculous question, but my engineering knowledge is minimal!

Hi all, to avoid any confusion especially to any New Members and to prevent misleading information (i.e. people getting the wrong impression) being published, can you please note the following :-

All the 83mm burr grinders mentioned so far in this thread are for "Home use"...the one exception being the Mazzer Major, this is a "Commercial" grinder and is designed and built primarily for "Cafe" (Starbucks, Costa etc. etc.) environments, although it can be used in a home environment is so desired (modded to single-dose).

N.B. When wording any comparisons between Home and Commercial items, caution should be used "very-carefully" (to avoid any misunderstanding) as this could be considered as unfair (it works both ways)...they are NOT the same...all the 83mm-burr-grinders mentioned so far (not the Mazzer Major) wouldn't survive long in a Cafe' with normal cafe' usage, as mentioned these grinders are aimed at a "different market" i.e. Home use.

The only thing that can be "compared" between any of the 83mm-burr-grinders mentioned is the taste in the cup. Taste in the cup is subjective.

With the above in mind i will not tolerate any bashing of "any" grinder regardless of name/make/model/price/other. Anyone doing so will have their post either Edited/Deleted as per the TOC's.

By all means all-members can express their "opinions", but please avoid anything that is either flaming-misleading-untrue-breaches TOC's to avoid this thread descending into chaos/other; i would hate to have to lock it. Please play nicely, play fairly and everyone wins :coffee:

FWIW he wasn't being "pulled up", it's just an opinion, no more, no less and i'm fine with that....but with some members it can depend on how it's worded or put across, words can have a dramatic effect or influence depending on how they are interpreted by another person...careful wording is all that is required to avoid for example 1+1 becoming 3.

Also, nothing has been deleted or edited :coffee:

I have just read some unbelievably wild claims regarding the duo from one of the chief testers. It worries me about how much of the information we read is true. These are the same people who throw shade on influencers when reviewing or making claims about products they are to my knowledge independently and fairly testing. Similar claims were made about the niche zero, now these views are superseded by the duos miraculous abilities. I have no doubt it’ll be good, value for money and brighter than a zero but do we really think it’s better and produce a better ‘sweeter shot than a lagom p100’ and ‘not tell the difference between a duo and Weber eg1?

You will only know if you bench test them all, sadly I don't have £6k spare to test 😅
