Cá Cơm Ruột Đỏ 60N is a premium traditional fish sauce produced by the Tĩn brand in Phan Thiết. It is made from carefully selected anchovies with characteristically red internal tissue that are caught during the main fishing season. The fish are salted shortly after being caught to preserve their freshness and natural protein content. The mixture then undergoes natural fermentation for approximately 36 months following a traditional method associated with the Phan Thiết area. Extended maturation allows the fish proteins to break down and develop a high concentration of natural amino acids. The 60N designation represents approximately 60 grams of total nitrogen per liter which places this sauce among the brand’s most concentrated products. Amino acid nitrogen accounts for more than 50 percent of its total nitrogen content. The sauce has a natural reddish-brown color, a dense texture and an intense umami character. Its flavor is powerful and complex with balanced salinity and a long mildly sweet finish.
