Most Canned Food
Because the canning process locks out oxygen, canned food will stay fresh for years—often far beyond the printed expiration date. Remember, though, that eating improperly stored canned goods can cause botulism, so if your cans look rusted or have deep dents or bulges, don’t eat what’s inside.
All kinds of sugar, including brown sugar, powdered sugar, and white sugar, will last indefinitely. Sugar can harden over time, but it's still safe to eat if you don't mind the texture. If the lumps really bother you, try softening the sugar by putting it in a plastic bag along with a damp paper towel and microwaving it for about 15 seconds.
Just like honey, pure maple syrup has low water content and can last for ages—which, given how much it costs, is a huge relief!
Distilled liquors like tequila, vodka, gin, whiskey, and rum last indefinitely, even after they've been opened. The only downside to keeping an opened bottle of spirits on the shelf is that it will slowly lose its flavor over time.

Another dried grain with a long shelf life, dried oats will last for years when stored in an airtight container.
