How long does brown rice last?

FoodKeeper gives brown rice 1 year unopened, as a US guide to quality. Once opened, that's 6 months in the fridge.

These are US figures, for quality. They come from USDA FoodKeeper. The date on a UK pack comes first, and Food Standards Agency rules take priority: never eat food after its use-by date. Best before is about quality.

How to store it

FoodKeeper gives it half the time of white rice, so don't buy more than you'll get through in a year. Keep it in a sealed container somewhere cool.

Keep it cool and dry. USDA says temperatures below 85°F (about 29°C) are best, and to avoid anywhere above or beside the cooker, under the sink, or in a damp garage or cellar. Reseal opened packs, or decant them into something airtight.

What to look for

Brown rice keeps its oily bran, so it's the smell that gives it away. Throw it out if it smells stale, sour or like old oil.

USDA says spoiled food develops an off smell, taste or texture. The FSA says you can smell food with a best before date to see if it has spoiled, but that the sniff test isn't safe for food with a use-by date.

Worth knowing

Cooked brown rice follows the same FSA rule as white: cool it quickly, keep it in the fridge, and eat it within 24 hours.

How it works

FoodKeeper is USDA's food storage database. Its figures are guides to quality for food stored at cool room temperature, not safety cut-offs, and we show them as USDA gives them. FoodKeeper counts this from the date of purchase. Opened times start when you open the pack.

There's no UK shelf-life dataset, so these figures are from the US. The date on your pack comes first. On a UK pack, use by is about safety and best before is about quality, so never rely on this page to go past a use-by date.

Common questions

How long does brown rice last unopened?

1 year, according to USDA FoodKeeper, as a guide to best quality. FoodKeeper counts this from the date of purchase.

How long does brown rice keep once opened?

1 year in the cupboard. 6 months in the fridge.

Can I eat brown rice after the best before date?

Best before is about quality, so brown rice past that date is usually safe, but may not be as good. A use-by date is different: never eat food after it.

What should I look for before using brown rice?

Brown rice keeps its oily bran, so it's the smell that gives it away. Throw it out if it smells stale, sour or like old oil.
