Types of Chinese soy sauce explained: light, dark, and everything in between
Published: April 29, 2026
Short Answer
Chinese soy sauce comes in two main categories: light soy sauce (生抽, shēngchōu) for seasoning and saltiness, and dark soy sauce (老抽, lǎochōu) for color and depth. Beyond these basics, there are mushroom-infused, thick (浓酱油), and seafood varieties, each with specific cooking applications. Understanding the difference is essential for Chinese cooking.

Deep Dive
Light Soy Sauce (生抽, Shēngchōu)
Light soy sauce is the workhorse of Chinese kitchens. It is the first extraction from the fermentation process — thinner, saltier, and lighter in color than dark soy sauce. Its primary role is seasoning: adding salt and umami to stir-fries, marinades, dipping sauces, and soups without darkening the dish. When a Chinese recipe calls for "soy sauce" without specifying, it almost always means light soy sauce. The color is a reddish-brown amber, and the flavor is sharp, salty, and clean. A splash of light soy sauce over steamed fish or stirred into a noodle soup provides the savory backbone that defines Chinese cooking. Good light soy sauce should list soybeans, wheat, water, and salt as its only ingredients — avoid brands with added caramel color or MSG (unless you want it, of course).
Dark Soy Sauce (老抽, Lǎochōu)
Dark soy sauce is light soy sauce that has been aged longer and often mixed with molasses or caramel, creating a thicker, darker, slightly sweeter product. It is used primarily for color — adding the rich, mahogany glaze to dishes like red-braised pork (红烧肉), lo mein noodles, and char siu. Dark soy sauce is less salty than light soy sauce but has a deeper, more complex flavor with notes of caramel and malt. Using too much dark soy sauce makes food look (and taste) muddy, so a little goes a long way. In red-braising (红烧, hóngshāo), the combination of light soy for salt and dark soy for color creates the signature glossy, deep-red sauce.
Thick Soy Sauce (浓酱油, Nóng Jiàngyóu)
Thick soy sauce is a specialty product, most commonly found in Cantonese and Southeast Asian Chinese cooking. It has the consistency of molasses — thick, sticky, and intensely dark. Used sparingly, it adds a deep, sweet-savory glaze to stir-fried noodles (like char kway teow) and roasted meats. In dim sum restaurants, thick soy sauce is often drizzled over rice noodle rolls (cheung fun). Lee Kum Kee is the most widely available brand for thick soy sauce outside China.
Mushroom Soy Sauce (蘑菇酱油)
Mushroom soy sauce is light soy sauce infused with dried straw mushrooms or shiitake mushrooms during the brewing process. The result is a richer, earthier, more umami-packed soy sauce that adds depth without additional ingredients. It is particularly popular in vegetarian cooking, where it replaces the meaty savoriness that might otherwise come from oyster sauce or fish sauce. Use it as a direct substitute for light soy sauce when you want more complexity.
Soy Sauce in Regional Chinese Cooking
Different regions of China favor different soy sauce styles:
- Cantonese cooking: Uses both light and dark soy sauce liberally. Thick soy sauce appears in noodle dishes. Cantonese soy sauce is often sweeter than northern varieties.
- Sichuan cooking: Uses light soy sauce as the primary seasoning, combined with doubanjiang (fermented bean paste) for depth. Dark soy sauce appears in red-braised dishes.
- Northern Chinese cooking: Uses soy sauce more sparingly — northern cuisine relies more on salt, vinegar, and garlic for seasoning.
- Shanghainese cooking: Heavy use of dark soy sauce for the signature "red-cooked" (红烧) dishes, combined with sugar for the sweet-savory balance Shanghai is known for.

Cooking Tips
- Never substitute dark for light soy sauce (or vice versa) — they serve different purposes
- Add light soy sauce early in stir-fries to season the ingredients as they cook
- Add dark soy sauce at the end of braising to control the color intensity
- Taste before adding salt — soy sauce is already salty, and many dishes need no additional salt
- Store opened soy sauce at room temperature for up to a year; it does not need refrigeration
