Single Dose Hopper for Macap M2M - a quick hack

[kopigeek]

I've got a variety of beans and of recently I have been single dosing so I thought I would quickly hack a hopper tonight.

I used a chrome coated small plastic cocktail shaker (the top half) and my (now useful) plastic tamper as a weight and lid.

It wasn't a perfect fit so I taped some foam to the bottom of it to make it snug.

Looks the biz

Indeed it does...

A lot more flash than my very basic hopper substitute kopi...

What are you using Mal?

What are you using Mal?

A plastic cup with the bottom cut out of it, and an aluminium tamper sitting inside the top....

Do you even need any hopper at all if you are single dosing ?
most of the grinders I have used held 50+ gms in the burr carrier with the hopper removed .
Tamper or glass spice jar used to prevent "popcorning"

I have a M4D and a 58mm basket fits perfectly on it

it kinda just sits there and stops any beans from escaping their inevitable death by grinding

A nominal 58mm Tamper/Basket or whatever, is too large to fit directly inside the throat of my grinder. Anyway, the extra storage offered by the plastic cup holds enough for three doubles, which is often all I need to make at any one time. Any more than that, and out comes the HUGE hopper...

The diameter of the throat on the M2M is 50mm and without a hopper of some sort a single 18gm dose is hard to fit in the throat of the grinder.

[lemoo]

ahh must be a smaller throat then, I just assumed they were similar diameters. my bad

i understand, but that is no longer a "single dosing" set up !

Hi Kopi,

Can you clear the chute on the m2m for single dosing? If I'm not mistaken, the doserless setup can retain quite a bit of coffee. For example, even after you grind everything in the hopper, there'll still be 3-4g(random number) retained from the burr chamber to just before chute. Effectively, you're mixing a bit of old grind into the new one. On the scale, you probably will still get what you put in (15g in, 15g out, but 3g out of that 15g may come from previous grind session). It's probably not that important, but you still need to pulse in order to evaluate different coffee correctly.

Hi mate. Yep you can clear the chute with a long thin brush or skewer.

I found that once I cleaned the chute and burrs it only retained less than a gram (but this is in no way a scientific test). Yes I do pulse.

Cheers mate. Thanks for the explanation.

I too single dose myself and have been looking for something that allows me to single dose without brushing/cleaning the chute. Looks like no gain again. :P I like to try different coffee at one time so single dosing is the way to go. Waste less coffee too.

I don't clean the chute though. I just give it a tap after each grind and some retained grinds fall out.

Sheesh... Picky picky.

99% of the time, a single coffee at a time is all I make....
