Why Do Dates Mould and Get Weevils?
Many buyers in Tangerang complain their dates quickly mould, get weevils, or harden. The cause is almost always the same: improper storage. Dates contain natural sugar and water which, if not handled correctly, become an ideal medium for mould and insects. The good news: with the right storage technique, dates can last for months — up to a year. This guide covers how to store each type of date.
First, Know: Dry vs Moist Dates
The first step is understanding your date type, because storage differs.
- Dry dates (e.g. Ajwa, Deglet Nour, Safawi) — low moisture, longer shelf life.
- Moist dates (e.g. Mazafati/Rotab) — high moisture, mould easily, need refrigeration.
Storage at Room Temperature
Dry dates last 3-6 months at room temperature, provided they are kept in a cool, dry place — such as a kitchen cabinet away from heat and humidity. Moist dates, by contrast, last only a few days at room temperature; mould can start growing in about 3 days. Therefore, moist dates should not be kept at room temperature for long.
Storage in the Refrigerator
The fridge is a date's best friend. Dry dates last up to a year refrigerated, while moist dates last about a month. Store dates in an airtight container before refrigerating.
Storage in the Freezer
For long-term storage, the freezer is the best option. Moist dates last about six months frozen. Freeze in small portions so you can take just enough without thawing your whole stock.
| Method | Dry Dates | Moist Dates |
|---|---|---|
| Room temperature | 3-6 months | A few days |
| Refrigerator | Up to 1 year | ~1 month |
| Freezer | Over 1 year | ~6 months |
Key Tips for Storing Dates
- Use airtight containers — plastic lunch boxes or airtight zip bags prevent mould and weevils.
- Avoid cardboard in the fridge — cardboard surfaces have gaps where bacteria can develop.
- Check regularly every 1-2 weeks — promptly separate dates that change colour, smell off, or mould.
- Keep out of direct sunlight — heat speeds up sugar crystallisation and hardening.
- Do not mix old and new dates in one container to avoid spreading spoilage.
Signs Dates Are No Longer Safe
Discard dates if white/green mould spots appear, there is a sour or sharp fermented smell, a slimy texture, or weevils/insects are present. White sugar crystals on the surface of dry dates are normal and still safe to eat — do not confuse these with mould.
