Clearing the Confusion: Why Do Different Fish Sauce Brands Taste So Different?

Many people have wondered why switching brands of fish sauce changes the taste of their dishes, even when using the same amount. Some brands are intensely salty, others slightly sweet, while certain formulas have such a strong aroma they overpower the main ingredients on the plate. The question is: why does fish sauce, which seems to have only fish and salt as its ingredients, vary so much in taste?

In reality, there are many factors that make “different brands of fish sauce taste different.” Everything from the type of raw materials, fermentation methods, fermentation period, to added ingredients, all significantly influence the taste, aroma, and quality of fish sauce. In this article, we’ll clear up these questions and compare various brands of authentic fish sauce to find out which one is the most delicious and best suited to your kitchen.

Factors That Affect the Taste of Fish Sauce

Although fish sauce may seem like a simple condiment, behind that small bottle lies a world of differences. It’s not just the taste, but also the aroma, color, and umami that directly affect your food. The secret to these differences lies in the production process and the raw materials each brand chooses. Let’s take a closer look at the key factors that give each fish sauce its distinctive character:

1. Type of Fish

The most commonly used fish in fish sauce production is anchovy, thanks to its small size, low fat content, and distinct aroma after fermentation. This results in a rich, mellow fish sauce without a fishy odor. Some brands, however, may use mackerel scad or other cheaper fish, which can lead to a harsher taste and stronger, less consistent fish smell.

2. Fish-to-Salt Ratio

High-quality fish sauce typically uses an appropriate fish-to-salt ratio, such as 3:1 or 2:1, ensuring enough fish to produce a naturally rich flavor. If there’s too little fish and the sauce is diluted with excessive water or salt, the result will be a sharply salty taste lacking the natural depth from the fish.

3. Fermentation Time

Fermentation time is another crucial factor in making authentic fish sauce. If it’s fermented for less than 6 months, the taste and aroma usually aren’t well-developed, and there may be a noticeable fishy smell. Meanwhile, naturally fermented fish sauce for over 18 months, such as that of Squid Brand, develops a fragrant natural aroma, clear golden color, and a mellow, non-harsh saltiness. Longer fermentation allows the fish enzymes to fully break down, creating a smoother, more natural taste compared to chemically adjusted sauces.

4. Additives: Sugar, MSG, Preservatives, and Flavor Enhancers

Some brands add sugar for a softer sweetness, MSG for instant umami, or preservatives to extend shelf life. However, these additives can compromise the quality of natural fish sauce and may not be suitable for those watching their sodium intake or avoiding additives. If your kitchen desires a truly “delicious” taste from 100% authentic fish sauce—free from sugar and MSG—then Squid Brand’s authentic fish sauce is your answer. Made from pure anchovies with no added flavorings, it enhances your food’s flavor without relying on artificial sweetness or preservatives, making it a favorite for health-conscious consumers.
