Bean Flour and oily spices

Hi Ginny,
Have you ground and used beans for flour and if so do you know if an aged bean would be hard maybe too hard for grinding and could this mill handle?? I have been stocking different beans for emergency food source,with hopes of buying a mill for multiple grinds of different grains and beans When reading above and came to oily spices I simply had to go google them... never thought of spices being oily or non oily... Glad that was part of the mill instructions!!
Thanks for reply!!

There have been some discussions (I think in the food preservation forum) about long-term storage of beans. I recall that the main issue is they get increasingly hard and it takes longer and longer soaking/cooking time to make them edible. I don't know that there is anyway to tell if a particular been would get too hard for any particular mill unless you already have the aged beans on hand.  I would speculate that humidity and other storage conditions would affect how had they get over time also.

Maybe better to plan on having fresher beans around?
