For milk I keep stocked up on evaporated milk and use it for cooking when fresh milk is called for to keep it rotated, including making vanilla custard ice cream. It keeps for and couple of years and would be so very beneficial.
For the flour, don’t forget to stock up on active dry yeast and vegetable shortening.
I try to keep stocked for a year of all non perishables. Canned chili and protein bars are good to keep.
I hate Spam and Goya’s similar version but I do keep it in stock. It’s good for five years usually and I’ve found a few recipes to enjoy it in, just to keep it rotated.
Paper goods and cleaning supplies I go for 2 years stock, some the plandemic. They’re not done messing with us.
One the initial expense is doled out you can just replace as used and it keeps it rotated at no additional cost.
Interesting - I haven’t made ice cream in a very long time - I be it does do pretty good job. My mom used to stock canned Milnot - yuck.
I have a couple of cases of powdered milk in # 10 cans. I used to try to stock canned milk, but I just didn’t have any use for it often enough to keep it rotated.
We opened a can of the powdered milk Jan. 2020, and I vacuum packed it in Qt. Jars, and put a pint in the cabinet. The pint is only half gone. Qts. haven’t been used - just checked to make sure the vacuum seal is still good.
I like to have at least a 3-5 year shelf life for the food.
You mentioned yeast, and that reminded me, I ran across my research notes the other day, and yeast will last 5 years in the freezer.
I have about a years worth vacuum sealed in bags in the freezer. It’s another item I don’t use often, but might use to make a couple of loaves of bread per week in emergencies or SHTF.
I use baking powder quite a lot more often than yeast. However, for my medium to longer term storage for that is cream of tartar and baking soda - they combine to make a substitute for baking powder.
Good idea for the paper products. We are working on expanding the storage area for those. We had about 9 months worth of T.P. when the Plandemic hit. Now we have about 14 months worth.
We need to get more paper plates etc.
