Niche Coffee Ltd - Duo

Have owned all the grinders on your list, at one point or another. Agree that Duo might be your best bet. Ability to play with other 83mm burrs is a good hedge against future curiosity. Recommend getting second (filter) burr option, because having the extra carrier for fast(ish) swaps is nice. Cannot recommend the Eurekas. Good build, very pretty, but burrs are proprietary and the grind chamber/chute design is antediluvian. Fine for hopper base on-demand grinding, but crap for single dosing. Even with the mods (tilted base, bellows), retention is terrible. Eureka’s attempts at single-dosing focused grinders are not honest efforts. Just a new model name and superficial accessories. And their new dial is just…stupid. Still not enough ratio to overcome the thread lash in their adjustment screw. The rev counter is nice enough, but a big dial like [this](https://www.amazon.com/ARO-EspressoTM-Eureka-Mignon-Adjustments/dp/B0CLCB8VQ6/ref=asc_df_B0CLCB8VQ6) is much more effective (and not stupid looking, imho) Libra portafilter contact sensor was unreliable. I heard they fixed it, but I had given up already and moved on. When it worked, it was…ok. Weight accuracy wasn’t bad, but irrelevant because it was a hot mess of sprayed grounds. RDT absolutely necessary in my environment (20-50%RH over the year), but the extra moisture caused caking/clogging in the chute. From a taste perspective…it’s ok. Blendy, decent body, not a lot of clarity. Little unkempt and harsh. Good in milk drinks. Niches — good workflow, probably among the best, even compared against titan grinders at 5x the price. Personally, not a fan of Mazzer burrs. Harsh and bitter finish. The Zero doesn’t have any options for their 63mm conical, so you’re kinda stuck. The stock Duo espresso burr was, to me, a cleaner version of Zero profile. Other options: Mazzer Philos. The grinder itself is a bit pricey, and rumor has it that the i200D and 189D burrs are big improvements over Mazzer traditional flavor profile — but it’s a good platform for 64mm burr space, where you are spoilt for choice and the burrs are cheaper than 83mm. Hope that helps

This, my gen 2 Ode makes fantastic v60/switch, Aromaboy and Aeropress brews. I also have a Niche Duo with both sets of burrs, the filter burrs are better than the ode, but not £500 better.

Why niche? OP wants to grind up to 80g in one go, and only uses French press, and sometimes V60 and aeropress. Why would they want an espresso grinder that isn't particularly great for filter brews? Especially considering that there's filter focused grinders like the ode 2 available for less money.

I mean, it's passable. It's very much a classic style espresso grinder and produces heaps of fines, this makes it super forgiving for dialing in espresso as it provides a pretty wide sweet spot, but isn't really ideal for V60 due to increased risk of clogging, or French press as it will result in a siltier brew. Not to mention the fact it can't grind those doses that OP wants to grind in one go. So if OP isn't brewing espresso, why spend more on a espresso focused grinder that does a worse job at filter brews than a filter optimised grinder that also happens to be cheaper?
