For a while I was thinking how to test retention properly.
What do you think about this technique?
1. After the grinder was used I remove the hopper and remove all beans I can reach with tweezers - I hope I can get all "unground" ones without shaking and tilting the grinder.
2. Put grinder cleaning pellets into the grinder.
3. Start the grinder and stop it as soon as I see white particles took over black particles
4. Weight that ground coffee
I know for a some time I will get a mix of coffee with pellets. But if I stop in time I will get some white particles out while I still have some coffee particles in the grinder too. So I assume it will even them out.
If it sounds reasonable I need to source small amount of grinder cleaning particles - I am not sure I need 400g of it.
Initially I though I could use green beans instead of cleaning pellets but people are saying green beans might damage the grinder (I suspected it so that's why I googled it in the first place).
