5. Traditional Production Process
Each type of traditional fish sauce follows its own unique production process with distinct family secrets. The production of Cat Hai Fish Sauce from Hai Phong is no exception. Sourced from abundant and diverse fish found in the Hai Phong coastal waters, such as anchovies, herring, squid, and others, only small, fresh fish caught using traditional net methods are selected for production. This is because these fish are easier to process and, more importantly, produce a superior quality fish sauce.
The production process has two main stages: the fermenting stage and the extraction stage, each requiring meticulous attention and care:
Fermenting Stage:
- The fish are cleaned and salted in a ratio of 100 kg of fish to 35 kg of salt (typically added in three stages) and 25 liters of clean water. Afterward, the mixture is placed in earthenware jars or stone tanks with tightly sealed lids. This stage facilitates the breakdown of proteins in the fish, aided by enzymes naturally present in the fish and microorganisms from the water, which together form amino acids. The fermentation time varies by season: during the summer, when there is more sunlight, the fermentation process takes around 4 to 6 months; in the winter, it can take 8 to 10 months due to less sunlight. Throughout this period, workers must monitor the fermentation carefully, ensuring the mixture is stirred properly in the sun, sheltered from rain, and regularly checked. Once the ferment has matured, the residue becomes fine like powder, settles at the bottom, gives off a fragrant smell, and has a clear golden liquid, signaling success.
Extraction Stage:
- The fermented mixture is then transferred to large wooden vats, each holding between 200-300 liters, where additional salt is added and the mixture is boiled twice before the fish sauce is extracted.
Depending on the quality of the fish sauce, the amount of salt and liquid extracted is adjusted. The proteins and flavors in the ferment are fully extracted during this process. Throughout the extraction, the fish sauce’s flavor must be constantly monitored to detect any issues. The final product is divided into three types of fish sauce based on its quality. On average, 1 ton of fish and 1,200 liters of water will produce 700 liters of first-grade fish sauce, 600 liters of second-grade, and 900 liters of third-grade fish sauce.
