I knew nothing about coffee grinders before I read your message. I've
now looked at about 20 of them on Amazon. They all seem to grind 3oz
at a time. If that's equivalent to liquid measure, unless it grinds
the 3oz in a few seconds, it would take us too long to grind all we do
at one time -- 12 cups or about 100oz

You need a *real* coffee grinder. Not the cheap little blender style
ones (like I have).
