CHIN-SU Premium Vietnamese Fish Sauce

FAQS ABOUT CHIN-SU Premium Vietnamese Fish Sauce

• What does "20° protein" mean in CHIN-SU Vietnamese Fish Sauce?

  It measures the total nitrogen content per liter of fish sauce, which indicates quality and anchovy concentration. 20° N means 20 grams of total nitrogen per liter. In fish sauce grading, higher nitrogen content reflects a higher fish-to-salt ratio and longer fermentation. At 20°, CHIN-SU Vietnamese Fish Sauce sits in the standard tier, balanced for everyday cooking and dipping use. Premium artisan fish sauces typically range from 30° to 40°N and above.

• What makes CHIN-SU Premium Vietnamese Fish Sauce different from other fish sauces?

  The anchovy source, the aging time, and the method behind it. CHIN-SU uses only carefully selected fresh anchovies from Vietnam, salted at sea immediately after the catch. The sauce is then aged for one full year using a centuries-old fermentation method passed down through generations of Vietnamese fish sauce craft. As Vietnam's No.1 fish sauce manufacturer, CHIN-SU applies that traditional process at a scale that maintains consistency across every batch.

• How is CHIN-SU Premium Vietnamese Fish Sauce made?

  Fresh Vietnamese anchovies are salted at sea, then aged for one year using a traditional fermentation method before bottling. The process begins with careful anchovy selection. Only fresh, high-quality cá cơm from Vietnam are used. The anchovies are mixed with pure salt and fermented for 12 months, allowing proteins to break down into amino acids that create the sauce's deep umami character. The liquid is then extracted, filtered, and bottled through a closed manufacturing process that meets international food safety standards.

• Can I use CHIN-SU Vietnamese Fish Sauce instead of salt in cooking?

  Yes. Use less fish sauce than you would use salt. CHIN-SU Vietnamese Fish Sauce adds sodium along with glutamates, amino acids, and natural flavor compounds that plain salt does not provide. One tablespoon, or 15 ml / 0.5 fl oz, contains 1,445 mg of sodium, which is roughly equal to one-third teaspoon of table salt but delivers much deeper savory flavor. Start with half the amount you would normally use for salt, then adjust to taste.

• Is CHIN-SU Vietnamese Fish Sauce gluten free?

  Yes, CHIN-SU Vietnamese Fish Sauce is gluten free. The formula contains no wheat, barley, or rye. Core ingredients are anchovy, salt, water, and sugar, with citric acid and natural flavor. If you have celiac disease or severe gluten sensitivity, check the current label before use, as formulas can change.

• Is CHIN-SU Vietnamese Fish Sauce keto-friendly?

  Yes, CHIN-SU Vietnamese Fish Sauce is keto-friendly at standard cooking amounts. One tablespoon (15 ml) contains 1g of total carbohydrate and only 15 calories. A ketogenic diet allows 20 to 50g of carbs per day (StatPearls, NCBI). At 1 to 2 tablespoons per recipe, the carb contribution is minimal.

• Is CHIN-SU Vietnamese Fish Sauce suitable for vegetarians or vegans?

  No. CHIN-SU Vietnamese Fish Sauce contains anchovy, a fish-derived ingredient. It's not suitable for vegetarians, vegans, or anyone avoiding fish or seafood. For plant-based cooking, soy sauce or coconut aminos provide a similar salty-umami function without fish content.

• How do I store CHIN-SU Vietnamese Fish Sauce?

  Keep the bottle in a cool, dry, ventilated area away from direct sunlight. After opening, close the cap tightly after every use. Refrigeration after opening is not required but extends shelf quality, particularly in warm kitchens. The glass bottle preserves the sauce's flavor better than plastic over time.

• How long does CHIN-SU Vietnamese Fish Sauce last?

  CHIN-SU Vietnamese Fish Sauce has a shelf life of 12 months from the manufacture date. Check the manufacture date printed on the packaging to know when your bottle expires. After opening, it keeps well for several months if stored properly with the cap sealed. Discard if the color darkens significantly past its normal amber tone or if the smell becomes sharply ammonia-like rather than the expected savory, briny note.

• Where can I buy CHIN-SU Vietnamese Fish Sauce?

  CHIN-SU is now available across the U.S. at leading retailers, including mainstream grocery chains such as Costco, Safeway, Albertsons, and World Market; Asian supermarkets like 99 Ranch Market, T&T, H Mart, JONS, and Thuan Phat; as well as online through Weee! and Amazon.
