I think ours is a 4qt? I recovered 2 qts of broth from a whole chicken carcass and it didn't really turn into jello in the frig, so I probably added a bit too much water. 12 cups is 3 qts and I'd guess you should allow at least another qt in volume for the bones. For regular cooking for a family of 4, I find ours is too large. If you really want to make 3qts of broth a week, I suppose it might not be.
