Shadow,

The flour and sugar is stored in big, heavy-duty plastic containers with wide screw-on lids. I'm not sure where DW got them. She has her "working container" in the pantry and her backup supply in several other containers in a big Rubbermaid tub under the stairs. As for rotation, DW is a big baker so she goes through flour/sugar pretty fast. In a normal week she'll make a triple-batch of pancakes, a dozen or more muffins, two dozen cookies, a platter of biscuts, two loaves of bread, dumplings, assorted gravies and sauces and a pizza crust from scratch. I think she goes through a 10-lb bag every month or so.

Hence my breakfasts/lunches of SlimFast.

Sugar stays good pretty much forever if kept dry and in the dark. She stores it the same way as the flour, a working conainer in the pantry and bulk storage under the stairs.
