It's wise to cross train on back up methods, with everything.
I generally get whole bean coffee. The electrical power in my area does get interrupted occaisionally from high winds and tree branches falling. I have a gas stove that I can light manually but I can't fire up the damn bean grinder until power is restored. A Mortar and Pestle would work with some determination.
If I had a Burr Mill hand crank grinder, I'd be in business, with ease 247365.
