Phu Quoc fish sauce, a Vietnamese delicacy, delivers rich, authentic flavours. This premium condiment comes from Phu Quoc Island, celebrated for its pristine waters and traditional fish sauce-making methods.
In this blog, we explore its history, reveal its production secrets, and highlight its significance, showing why chefs and food enthusiasts worldwide treasure it.
The History of Phu Quoc Fish Sauce:

This sauce boasts a legacy that spans over 200 years. The tradition began with local fishermen who sought ways to preserve their abundant fish catches.
Over time, they perfected the art of fermenting fish with salt, giving birth to the exquisite fish sauce we know today.
The island’s unique geographical location is pivotal in the sauce’s distinctive flavour. Phu Quoc is blessed with clear waters rich in anchovies—a key ingredient in fish sauce production.
Generations of islanders have refined their craft, ensuring that each bottle captures the essence of the region’s culinary tradition.
How is it Made?

The production of this sauce is an intricate process that emphasizes quality and tradition. Here’s a closer look at how it’s made:
1. Selecting Fresh Anchovies
Phu Quoc’s fishermen prioritize small, silver anchovies for their rich protein content. These fish are harvested fresh from the waters surrounding the island.
2. Mixing Anchovies with Salt
Producers mix fresh anchovies with high-quality sea salt in a precise ratio—three parts fish to one part salt. This blend preserves the fish and kick-starts the fermentation process.
3. Fermentation in Wooden Barrels
The mixture is placed in large wooden barrels made from a local wood known as “boi loi.” These barrels allow natural fermentation, which can last 12 to 18 months. The slow process develops the sauce’s deep umami flavour and amber hue.
4. Extracting the Essence
Producers draw the first extraction, known as “nước mắm nhÄ©,” once fermentation finishes. They prize this pure, concentrated sauce for its superior taste and aroma, while subsequent extractions yield lighter versions.
5. Bottling and Sealing
The fish sauce is filtered, bottled, and sealed to preserve its authenticity. It is often labelled with its origin to guarantee its quality.
What Makes It Unique?

1. Protected Geographical Indication (PGI) Status
Phu Quoc fish sauce is the first Vietnamese product to receive Protected Geographical Indication (PGI) status from the European Union.
This certification ensures that only fish sauce produced on the island using traditional methods can bear the name “Phu Quoc.”
2. Natural Ingredients
Unlike mass-produced fish sauces, it contains no artificial additives or preservatives. Its rich flavour derives from anchovies, salt, and time-honoured techniques.
3. Superior Taste
The slow fermentation process enhances the sauce’s umami profile, making it a favourite ingredient for chefs. Its complex flavour can elevate any dish, from marinades to dipping sauces.
