Pantry Staples and How Long They Really Keep

The pantry is where "best before" gets most misunderstood. Dry goods are stable and long-lived, so a lot of them are perfectly fine well past the printed date — but they aren't immortal, and how you store them makes a big difference. Here's a realistic guide.

Long-life staples

Kept cool, dark and dry, these keep for a year or more:

• Flour: about a year (wholemeal a bit less, as the oils go rancid faster)
• Sugar: effectively indefinite if kept dry
• Rice and dried pasta: a year or more
• Canned goods: 1-2 years, often longer
• Oats: around a year

Medium-life staples

• Cereal: about 6 months once opened
• Cooking oil: roughly a year; keep it away from heat and light
• Honey: basically never spoils — it may crystallise, but gently warming fixes that

Storage makes the difference

Three enemies shorten a pantry's life: heat, light and moisture. Keep staples in a cool, dark cupboard, and decant opened bags of flour, rice and sugar into airtight containers to keep pests and humidity out. Want a specific timeline? The Food Shelf Life Calculator covers pantry items too.

What doesn't belong in the pantry

Some things people shelve should be chilled, and vice versa. Potatoes, onions and garlic love the pantry; nut butters and opened sauces often prefer the fridge. When in doubt, the Where to Store Food tool sorts it out.

Track the pantry too

It's not just fresh food that gets wasted — half-used bags and forgotten cans pile up at the back of the cupboard just as easily. PantryKit tracks pantry staples alongside your fridge and freezer, so you know what you have before you buy another bag of rice you didn't need.
