Storing Dried and Double-Boiled Bird's Nest: How Long Does It Keep?

The first date to check is the shelf life printed on the box. Yến Sào Uyên Nguyên's dried nest boxes carry a printed shelf life of 24 months and contain a moisture-absorbing sachet. This date is for dried nest that has not been double-boiled, still in its box and stored properly; it is not how long soaked or double-boiled nest keeps (see the sections below).

When the original packaging is gone, reference sources give different figures, but all require the nest to be dry, sealed and kept away from moisture:

Long Chau also notes that after a long time the nest may not have spoiled but its quality is no longer as good as when it was bought. So buy an amount you will use within a few months rather than stockpiling.

According to Long Chau pharmacy (opens in a new tab), moisture is the biggest enemy of dried nest because it allows mould to grow. The sources checked give no specific temperature or humidity figures for dried nest, but agree on the following principles:

1. 1Step 1: Keep it in a clean glass or plastic container with a tight lid; a vacuum bag is best (Pharmacity (opens in a new tab)).
2. 2Step 2: Keep it in a dry, cool place; avoid direct sun and places with sharp temperature swings, such as near the stove or a sunny window (Pharmacity (opens in a new tab)).
3. 3Step 3: You can line or wrap the nest in paper before putting it in the container; if storing for long, change the paper from time to time and check for signs of mould (Long Chau (opens in a new tab)).
4. 4Step 4: In a humid climate, close the lid tightly right after each time you take nest out (Long Chau (opens in a new tab)).
5. 5Step 5: Keep it away from spices, cigarettes and chemicals because the nest picks up smells easily; use dry, clean utensils when taking nest out (Pharmacity (opens in a new tab)).

If the nest you bought is not fully dry (soft to the touch, not crisp), Long Chau advises drying it with a fan for about 8–12 hours until it is hard and crisp before storing.

You can, but it is not required. Pharmacity (opens in a new tab) allows dried nest in the cool compartment, provided it is in an airtight box or vacuum bag so the nest does not absorb other food smells. For completely dry nest, a dry, cool place at room temperature is enough.

The freezer is for nest that is not fully dry. Long Chau (opens in a new tab) advises that nest not yet fully dried should go in the freezer to keep longer.

It is best to double-boil right after soaking (Pharmacity (opens in a new tab)). If you soaked too much, soaked nest (also called fresh nest) must be drained and kept cold:

Sources give quite different figures, from 24 hours to 10 days. Yến Sào Uyên Nguyên lists them all so you can compare:

Mould can contaminate nest during processing, storage or transport (Yeo et al., 2021 (opens in a new tab)). Throw the nest away if you see any of these signs:

• An unpleasant or odd smell (Pharmacity (opens in a new tab)).
• Black or green spots on the surface (Pharmacity (opens in a new tab)).
• Dried nest that feels slimy or unusually soft (Pharmacity (opens in a new tab)).
• Nest that turns brown or black (Long Chau (opens in a new tab)).

Nest that has an odd smell or mould should not be eaten (Pharmacity (opens in a new tab)). Do not try to dry it or wash it again to keep using it.

• Opening the box more than necessary, or taking nest out with a wet spoon or hand (Pharmacity (opens in a new tab)).
• Keeping the nest box near the stove, next to a sunny window or near spices and cigarettes (Pharmacity (opens in a new tab)).
• Putting dried nest in the refrigerator without sealing it, so the nest picks up smells (Pharmacity (opens in a new tab)).
• Soaking too much nest and leaving it wet at room temperature.
• Leaving double-boiled nest on the table for more than 2 hours before refrigerating it (WHO Europe (opens in a new tab)).
• Double-boiling a big batch to keep for a whole week, especially when red dates or lotus seeds are added (Hello Bacsi (opens in a new tab)).

Dried nest keeps much longer than ready-double-boiled nest, so it suits buying early for the Tết season. A few notes:

• Check the shelf life printed on the box when you receive it, and choose boxes with a long date left.
• Keep the box sealed, in a dry, cool place until the day you give it; do not leave it in a car boot or somewhere hot and sunny.
• When giving it, remind the recipient to close the box tightly after opening and to double-boil it following the instructions.
• Do not double-boil nest in advance to give as a gift, because double-boiled nest keeps only a few days.
