34 Độ Đạm is a traditional fish sauce produced by the Luận Nghiệp brand in Vietnam’s Hà Tĩnh Province. It is made from fresh anchovies sourced from the nearby Hải Khẩu fishing port and purified sea salt. The fish and salt undergo natural fermentation in large ceramic jars that are regularly exposed to sunlight. During maturation the liquid is drawn from the bottom and returned to the jars to ensure the even breakdown of fish proteins. Fermentation lasts for at least 24 months after which the matured fish sauce is extracted. The 34N designation indicates that the product contains approximately 34 grams of total nitrogen per liter with a permitted variation of one gram. The sauce has a clear golden-brown color, an intense anchovy aroma and a full savory-salty flavor with a naturally sweet finish. Its only ingredients are fresh anchovies and sea salt with no additives or preservatives. During storage its color may gradually darken while the formation of salt crystals is a natural characteristic of traditional fish sauce.
