I'd stay away from large quantities of single types of foods like grains, as they can be difficult to prepare and require processing. Unless you plan to live out of such a thing for weeks or months, unnecessary.

Huh. I don't see that from my perspective - I mean, yeah, you can't use uncracked wheat berries for much without doing something-- making flour, malting, sprouting, cooking. But, I don't see the problem with that. I'm not going to be living on microwave dinners. The grains will store MUCH more stably in this state than as flour or prepared foods- in many cases decades more storage time.
I also find that with large amounts of staple foods and spices you have more variety possible in cooking. And- we always have focused on keeping a rotation of stuff we actually
use for the year's supply style pantries.
some additional items as a more or less detailed bulk listing:
powdered whole milk
powdered cheese
whole grains:
wheat
rye
barley
brown rice
wild rice.
steel cut oats.
honey in large glass jars (this one you can get away with not rotating. keep it for 20 years and then donate to a homebrewer and buy more. Have 25 pounds or so of inexpensive local RAW honey)
crisco
canned lard
canola oil
sprouting supplies including seed.
freeze dried greens and some fruits. (Be careful that you get stuff you cna actually use in soups and desserts so you can rotate, and don't go crazy- it's expensive and even in a hardcore depression you should manage to find rocket and dandelion and kale and chard easily.)
Canned meats have a definite shelf life, so make sure you get a one year rotation out of your spam and tuna. If you don't *eat* it, don't stock it. - You get your classic 4 cases of MREs for stuff like that. (and some of the MRE main courses are great to add to a pot of rice, for example. BTDT)
A case of bottled water, in regular .5 liter containers, is 3 gallons of water. Keep 2 or 3 cases, and rotate tha in and out as your year goes by- the bottles are useful. Seriously look into getting some real water storage, though- you want way more than 9-15 gallons. My grandparents have 3 old CDC 55 gallon sealed drums they built a breakfast bar around in their shelter. Works pretty well.
