Gukganjang (Korean Soup Soy Sauce) is a traditionally fermented Korean soy sauce that differs significantly from the Japanese or Chinese soy sauces commonly found in supermarkets. The key differences lie in colour and purpose. Gukganjang is much lighter and more translucent in colour, so adding it to soups or stews does not darken the broth. At the same time, it is considerably saltier than regular soy sauce. It is used in small quantities to season Korean soups, seasoned vegetable dishes (namul), and stews. To draw a familiar European comparison: if regular soy sauce is like red wine vinegar, Gukganjang is closer to anchovy fish sauce — an intensely savoury umami seasoning used sparingly for depth.

That is correct. Sempio Gukganjang contains approximately 19g of salt per 100ml, making it a very high-sodium product. This is characteristic of traditional Korean Gukganjang — it is a highly concentrated fermented seasoning designed to deliver strong flavour in very small amounts. When cooking, do not add a large quantity at once; instead, add a teaspoon at a time and taste as you go. This product is not a low-sodium or reduced-salt product. Those who need to limit sodium intake (e.g. due to high blood pressure or kidney conditions) should use it with particular care.

Before opening, store in a cool, dry place away from direct sunlight. After opening, seal the cap tightly and refrigerate. While Gukganjang's high salt concentration gives it strong natural preserving properties, refrigeration after opening is recommended to maintain quality. This product contains Preservative E211 (Sodium Benzoate). For the exact best-before date, please refer to the date printed on the product label. As an 860ml large-format bottle, it offers excellent value for those who cook Korean dishes regularly.
