Whole foods has or can get you bags of winter wheat berry's. I have been storing popcorn from sam's cub for 2 or 3 years now in the big 5 gallon water bottles. So far looks good. Popcorn makes really good corn bread. and can strech out the wheat flour for less than a third of the price of wheat berry's. $16.?? for 50 lb bag IIRC.
