A little emergency supply of ground coffee would be a wise idea, agree.
Of course, one may eliminate personal grinding at all and rely on the ground coffee from a shop totally... but that would be a 'second grade', figuratively speaking, one will steal a good chunk of fun from himself.
Manual grinders are different, thats for sure. I tried only this certain model, and it is very very dated. I know I should update my experience with more up-to-date models - maybe my experience will change dramatically to better? It, just, did not happened yet, so theres a plenty room for further explorations. Which is a good thing. Have a Hive !PIZZA from me, dear friend, and best wishes. 🐈
