First lets take a look at what most folks do in the pantry with regards to canned goods:
Now this is basically a good idea and if you have the room you can group a tremendous amount of stuff together and you'll have some basic organization. However, how do you control what is expired and what is not? Do you fish around through all those cans to get the expiration dates? Probably not and that can be really time consuming. This was my problem (although that's not a picture of my storage by a long shot) so I decided to research some ways to help me not loose inventory to expiration, and also to help me get a better picture of what it was that I needed and to stop overstocking of some items and falling short on others.Looking at Can storage I found some very clever adaptations to the normal pantry shelf. One was a vertical storage method that fit between the joists in your wall. The good people over at Pharoah's Storehouse provide methods and instructions for clever use of the voids in your walls.
Another way to store cans with the same FIFO philosophy is a horizontal method. This is more oriented towards shelves and the racks can be stacked or even built to hold large amounts of cans. Horizontal racks look like this:
Either way, keeping your shelves organized will benefit you and your family by being efficient, clean, safe and will save you money in terms of correct inventory. With the fall coming up it's a great time to stock up on canned goods and you'll need the new space.

Of course you can just go the normal route and buy an extra 5 or 10 dollars worth of canned goods everytime you go food shopping and in just a short period of time you'll have a good supply on hand. Here's a link for the extreme length you can go: Costco
