These are my "three amigos". Soft White Wheat, Hard White Wheat, and Oatmeal. We go through alot of these grains here so we buy them in bulk (to save money and to be stocked up). I keep them in these 5 gallon (food grade) buckets with Gamma lids that screw on and off. Gamma lids are AMAZING!!! If you keep your food/grain stock in 5 gallon buckets then you definitely need to look into gamma lids!
We also have smaller buckets of long grain brown rice and various beans...but we sure dont go through quite as much of those as we do these 3.
