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.

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.
