Types and Vintages of Fish Maw: Why Aged Fish Maw Becomes More Valuable
Fish maw shares a commonality with red wine – aging makes it more valuable. Freshly dried fish maw has a fishy smell and its gelatin hasn't fully transformed, making its texture and nutritional value inferior to aged products. Generally, fish maw stored for over 10 years will have a more stable collagen structure, resulting in a better texture and taste when stewed compared to new stock. Hence, the old adage "the older the fish maw, the better" holds true.
The type of fish maw greatly affects its price. Money Maw (Yellow-lipped Fish Maw) is recognized as the most precious variety because the Yellow-lipped Fish is extremely rare, with an aged piece of Money Maw potentially worth hundreds of thousands or even over a million. Spider Maw (Grouper Fish Maw) has seen a rapid price increase in recent years due to declining wild grouper populations. White Flower Maw (Croaker Fish Maw) is relatively more common, but aged White Flower Maw still has potential for appreciation.
The identification of cordyceps is more complex. Genuine wild cordyceps from Naqu and Yushu can differ in price by dozens of times compared to artificially cultivated cordyceps. Identification mainly relies on the size of the insect body, color (authentic ones are yellowish-brown), smell (a faint mushroom-like aroma), and the texture of the cross-section. There are also cases of using Isaria sinclairii and Liangshan cordyceps as fakes, so professional identification is crucial.
For dried goods, it's important to prevent moisture and insects. Fish maw is best stored in sealed bags with desiccant in a cool, ventilated place; cordyceps is recommended to be sealed and refrigerated to prevent oxidation and deterioration. Well-preserved dried goods can yield better returns than many investment products if sold a decade later.

Frequently Asked Questions
How much is one tael of cordyceps worth?
Top-grade wild Cordyceps from Naqu, Tibet, is priced at HKD 8,000–18,000 per tael (37.5g); Cordyceps from Yushu, Qinghai is approximately HKD 5,000–12,000; wild Cordyceps from Yunnan is cheaper. The specific price depends on the size (plumpness of the insect body, completeness of the grass head).
How is the vintage of fish maw determined?
Aged fish maw tends to be darker golden yellow, with clear textures and natural cracks; new fish maw is lighter in color with shallower textures. We use UV light, touch, and smell to comprehensively assess the vintage.
Is bird's nest graded?
Yes, by shape: Swiftlet > Strips > Corners > Crushed. By origin: Indonesia > Malaysia > Vietnam. We evaluate based on the swiftlet's weight in grams, whiteness, and impurity content for a comprehensive appraisal.
Do you still accept cordyceps that is 10 years old?
It depends on the storage condition. Cordyceps stored sealed and refrigerated (in the fridge) for within 10 years, if in good condition, can still be pre-owned. If it has been exposed to moisture at room temperature, infested with insects, or molded, we will not accept it. We recommend sending photos for our assessment.
