Nino takes 2.8 sec to grind a 14g double.

This is harsh, even for April Fool's. Define "better". Less clumpy grinds? Sure, that's the one clear benefit that a doser provides in a home setting: it helps break up clumps.* Otherwise, I prefer doserless designs, even the retrofits. Doserless grinders are quieter, less wasteful, and less messy than dosered grinders - all factors that are of much greater significance in the home setting than a busy commercial environment.

The basic problem is not dosered vs. doserless, it's the poor design of the exit chute from the burr chamber on most commercial grinders. A horizontal chute, with or without a wire grid, practically guarantees some grind buildup and compression, resulting in chunks (or in some cases, coffee cubes ). A better design would not cause chunks in the first place.

* BTW, I know of at least one other way to address this problem.

Getting off-topic here, but John's post did make me wonder: Has anyone ever tried reorienting their Mazzer so the chute faces downward at a 45 or 90 degree angle? The primary concerns would be:

1. Performance of the motor in a non-vertical orientation
2. Devising some kind of stand to hold the grinder in the proper position
3. Keeping the beans feeding consistently

Just some thoughts for you doserless fans. Personally, I love the fluffy distribution I'm getting from my tweaked Mazzer doser.

I can't really agree with you here Jim, I think the funnel works very well ...

The funnel is great. It collects the shot you ground the last time perfectly. The shot you ground this time is behind that grid.

Hi Jim,

the grid holds around 3g of coffee, quick purge and it's gone. I agree the whole idea of having a flat 'corridor' between the burr chamber and the funnel/doser is not awesome, but the grinder still works very well.

The main problem is probably static (link to Jacob's attempt to mod his Robur exit chute).

I disagree on most of these counts. The only noise difference would be operating the doser (some clack louder than others), but as far as mess and waste goes I find that I have less mess and less waste using my doser grinders that with the doserless. For disclosure, my Mazzer doser has some simple modification so that it sweeps very clean and I have been loading per shot and grinding through completely which also helps to virtually eliminate waste.

yea yea yea......we know, we know

But I think this is relevant in another way....I feel like the WDT funnel helps me keep mess to a minimum with either a doser or doserless grinder. I have owned both doser and doserless-designed grinders as well as having modified a doser grinder to be doserless. In all cases I have found the WDT funnel to be very helpful in reducing mess and waste.


As for grounds behind the screen of a Mazzer doserless....these can also be brushed out if done carefully and with the right type of brush. When I was using a doserless Super Jolly I was able to reduce waste to a minimum just like I do now with other grinders. I prefer the dosers because brushing the chute is much less of a PITA.


Of course the Mahlkoenig eliminates much of this altogether. It is a freakishly quiet coffee dispenser that leaves very little (if any) coffee in the chute. I have one of he buttons set up for a short pulse to clear the burr area, this causes waste from keeping the hopper loaded but that's a small price IMO for the added convenience. The downside of this one is that it is definitely more messy than my doser grinders.

Of course I was referring to the noise of the doser lever going THWACK-THWACK-THWACK. Grinding noise will be similar, with or without a doser. I have tried most of the doser mods, and remain convinced that some grinds are always retained in the doser. I have never tried a wire screen over the chute, so grinds retention in the chute is the same - except that, with some (non wire grid) doserless mods, it's easier to brush out the chute.

I realize that I'm in the minority on the doser vs. doserless issue. So what else is new?

Let's see: fast, quiet... and doserless. I'd like to hear more about the burr and exit chute design.

A couple of years ago, someone posted a pic of a Mazzer on an inclined board (#2 above) on CG. Sorry, I don't have the time to search for it right now...

Hi guys,

That's the main difference for me, I don't load per shot anymore:) mostly because of the funnel design.
