Tĩn 41°N fish sauce is a premium Vietnamese anchovy fish sauce made following a 300-year-old traditional recipe from Phan Thiết. Made from first-press (rin) anchovies naturally fermented for 24 months with pure sea salt in wooden barrels. The 41°N designation indicates high protein content (41 degrees of nitrogen per liter), making it a premium grade fish sauce compared to typical mid-20°N commercial varieties.

This traditional fish sauce is carefully stored in earthenware jars shielded from direct light, allowing continued fermentation for deeper flavor. Features a rich, full-bodied umami taste with dark brown color characteristic of authentic aged fish sauce. No preservatives, additives, or artificial ingredients. The fermentation process uses a ratio of 3 parts fresh anchovies to 1 part pure sea salt, following the ancestral methods established by Tran Gia Hoa, the founder of Vietnamese rin fish sauce production.

Perfect as a dipping sauce, marinade, cooking seasoning, or base for Vietnamese cuisine. Manufactured by Seagull Company Limited in Phan Thiết, Vietnam, and imported exclusively by Lee Bros. Foodservice, Inc. Product of Vietnam.
