Every morning before grinding I already empty the exit hole (the small channel between burrs and chute) of my (doserless) Mazzer Mini Electronic with a small stiff brush and then I also grind a few seconds and dump that, so that I don't use the old trapped coffee.
However I wonder if it is also benificial and recommended to do this before every new shot if there has been some time, e.g. 1 hour, between shots.
What is your opinion ?
