How long does white rice last?
Uncooked white rice lasts about 4–5 years in its original bag and 25–30 years when sealed in Mylar bags or #10 cans with oxygen absorbers in a cool, dry place.
| White Rice | |
|---|---|
| Unopened | 4–5 years in the original bag |
| Opened | 1–2 years in an airtight container; cooked rice 4–6 days in the fridge |
| Ideal storage | Airtight, dark, dry and cool (below 70°F / 21°C). |
| Long-term | 25–30 years sealed in Mylar or #10 cans with oxygen absorbers (BYU long-term storage studies). |
Storage tips
- Paper and thin plastic retail bags let in moisture and insects; repack rice you plan to keep more than a year.
- Freezing new rice for 3–4 days before repacking kills insect eggs.
- Use food-grade buckets with Mylar liners for bulk storage; plain buckets are not airtight enough on their own.
- Parboiled and instant rice store well too; brown rice does not (see brown rice).
Signs it has gone bad
- Insects, larvae or fine webbing (pantry moths) in the package
- A musty, sour or moldy smell, or visible mold
- Clumps or damp patches from moisture getting in
- A sharp, paint-like or bitter smell, which means the natural oils have gone rancid (brown rice, oats, whole-wheat flour)
