Thought this might interest some folk - a cheap (free) storage solution so make it simple and space efficient to store and retrieve your canned goods. Hope the pic works...
I got these bakery crates from my corner shop (with permission - the baker never collected and he had about 150 stacked up in the way!)
They are very strong and stack/lock together very safely. And a normal 12 can slab from the whole saler fits perfectly into one row, two cans high.
That looks a good one, i use office metal filing cabinets, they are cheap second hand, impossible to steal and can be locked, keep out light and any pests
Since one 12 can slab fill one "slot", my plan to rotate is -
when a slot of 12 cans run out, buy a new slab to refill that slot, but start taking cans from the next slot along. I have dated each slot with the use by date.
It is easy enough to reach in and take can from the back of the slot.
Cans last a lot longer than their sell by date. I can't tell from the picture where your racks are but I would make sure they are kept cool as heat drastically reduces the life of the food.
I had a tin of soup last week that had a sell by date of January 2007 and it was fine. My wife had a mugshot that was 2006 but they are dehydrated and I would eat something like that or a pot noodle if it was donkeys years out of date.
Last month I had a tin of pears that was 2006 and they were perfectly fine. Not sure if they still have as much nutritional value after that long but I wasn't ill.
Rotating is obviously correct, I am just syaing don't throw anything out if the sell by date has expired. Obviously that does not apply to dairy products.
