1.1. Overview of Nam O Da Nang fish sauce

Nam O Da Nang fish sauce is the culinary essence characteristic of the Central region, with a history of over 400 years. The product is made in Nam Ô village and has become a culinary icon and the pride of the local people.

The difference of Nam Ô fish sauce compared to other types lies in its distinctive dark reddish-brown color and rich, harmonious taste.

3.1. Special Ingredients

The superior quality of Nam O Da Nang fish sauce stems from meticulous ingredient selection. Black anchovies are purchased only when they meet freshness standards and are uniform in size, mainly caught near the coast of Da Nang from the 11th to the 4th lunar month – the time when anchovies have firm flesh, are less fishy, and have the best flavor.

Pure granular salt also plays a key role in the production process. Traditional craftsmen prefer to use Ca Na and Sa Huynh sea salt – a type of salt that is white, clean, has few impurities, and meets high-quality standards. Before being used for fermentation, the salt is usually aged for at least one year to reduce its astringency, and simultaneously helps the finished fish sauce have a natural, delicate sweetness.

The secret to creating the peak flavor of Nam O Da Nang fish sauce lies in the traditional fermentation process preserved through many generations. Fresh black anchovies are combined with sea salt in a 3:1 ratio, ensuring a harmonious balance between protein from fish and minerals from salt, delivering a moderate saltiness but a natural richness.

The mixture of fish and salt is then fermented in wooden barrels or large jars, for a period of 12 to 18 months, even longer for batches requiring high quality. The technique of alternately arranging stones and bamboo mats is applied subtly, helping to increase ventilation, control temperature, and create favorable conditions for the natural fermentation process.

Throughout the fermentation process, the fish sauce makers regularly check and stir the jars to ensure each batch of fish sauce achieves stable quality. This meticulousness and patience in each of these steps is the decisive factor in creating the characteristic and standard flavor of Nam O fish sauce, making the product a source of pride for Central Vietnamese cuisine.

3.3. Filtering Prime Fish Sauce Process

After the extended fermentation process, Nam O Da Nang fish sauce is carefully filtered through fine cloth or a mechanical filtration system to extract the first liquid – usually classified as grade 1, standing out with the highest quality. This stage requires delicate technique to completely remove sediment while fully preserving the quintessential natural flavor.

The finished product achieves high protein content, ranging from 30-40 degrees, reflecting the rich protein content formed through the natural fermentation process.
