3. Secrets that create Nam Ô Da Nang fish sauce
3.1. Excellent ingredients
Black anchovies are the most important, indispensable ingredient that creates the quality of Nam Ô Da Nang fish sauce . This small fish usually lives close to the shore, has a slender body, and shiny silver-blue scales. During the season from January to April of the lunar calendar, black anchovies are at their most delicious and protein-rich. Fishermen in Nam Ô often go out to sea around 3-4 AM to keep the fish fresh until they reach the shore.

The fish selection process is extremely strict. Only the freshest batches of fish, not broken, and of uniform size are kept. The fish are cleaned with seawater, completely removing mixed fish, ensuring only high-quality anchovies are retained. With 1 kg of fresh fish potentially containing thousands of small fish, the selection process requires the artisan to be very meticulous.
The sea salt used in Nam O Da Nang fish sauce is mainly sourced from famous places like Ca Na (Ninh Thuan) or Sa Huynh (Quang Ngai) with the advantage of large grains, pure white, and stable saltiness. The salt is thoroughly dried for many months before use, completely removing impurities. The ratio of fish to salt must be between 25-30% salt to facilitate the fermentation and preservation process.
3.2. Traditional Fermentation Process
The mixing of fish with salt in the standard ratio is a professional secret passed down within families making Nam O Da Nang fish sauce. Typically, the ratio of three parts fish to one part salt has been maintained since ancient times. Fresh fish, after being mixed with salt, are placed into thoroughly cleaned earthenware jars or large wooden barrels.
The pressing of salted fish requires skillful technique. The mixture of fish and salt needs to be pressed tightly, without leaving any air pockets inside. This helps create even pressure, stimulates the fish to release liquid, and initiates the natural fermentation process.
After being mixed with salt, the fish will ferment for a period of 12 to 18 months, with some families even fermenting for up to 24 months to create high-quality Nam O Da Nang fish sauce. Throughout this process, the fish sauce barrels will be checked periodically, gently stirred, and salt added as needed. The ideal conditions are a cool, wind-protected place, with temperatures maintained between 25 and 30 degrees Celsius, avoiding direct sunlight for the fish sauce to reach standard.
4. Characteristics and Quality of Nam O Da Nang Fish Sauce
4.1. Sensory Characteristics
Traditional Nam O Da Nang fish sauce has a reddish-brown color with a natural red sheen when held up to the light, creating a particularly appealing sensation.
