This week, I made a batch of bread in the evening and was short on time so I used some whole wheat flour I had in the cupboard to use it up, rather than grind my own. I didn't realize how old the flour was and how the age of the flour affected the flavor of the final product until now.  The bread was picture perfect-great texture and chew but it tasted.......old. It tasted like old oil. Yuck. The rest of the flour is going in the garbage! From now on-fresh milled for me!
