Soy Sauce Vs Lao Chou: What’S Your Favorite?

Soy sauce, a ubiquitous condiment in many cuisines worldwide, is a fermented liquid made from soybeans, wheat, salt, and water. Its complex and savory flavor profile, known as umami, has made it a staple in kitchens for centuries.

Production Process

Soy sauce production involves a multi-step process:

1. Soaking and Cooking: Soybeans and wheat are soaked and cooked together to soften them.
2. Koji Inoculation: The mixture is inoculated with a koji mold (Aspergillus oryzae) to initiate fermentation.
3. Fermentation: The koji transforms the carbohydrates into sugars, which are then converted into alcohol and amino acids by yeast.
4. Pressing: The fermented mixture is pressed to extract the liquid, which is known as moromi.
5. Aging: Moromi is aged in barrels for several months to develop its characteristic flavor and aroma.
6. Pasteurization: The aged sauce is pasteurized to kill any remaining microorganisms and extend its shelf life.

Types of Soy Sauce

Soy sauce varies in flavor and texture depending on the ingredients, fermentation time, and aging process. Common types include:

• Light Soy Sauce: A thin, light-colored sauce with a delicate flavor.
• Dark Soy Sauce: A thicker, darker sauce with a stronger, more robust flavor.
• Tamari: A wheat-free soy sauce made from 100% soybeans.

Lao Chou: A Traditional Chinese Fermentation

Lao chou, also known as “aged vinegar,” is a fermented liquid made from glutinous rice, water, and a starter culture. It is a centuries-old Chinese condiment with a unique sour and savory flavor.

Production Process

Lao chou production involves the following steps:

1. Soaking and Steaming: Glutinous rice is soaked, steamed, and cooled.
2. Starter Culture Inoculation: The cooked rice is mixed with a starter culture, which contains microorganisms that initiate fermentation.
3. Fermentation: The mixture is fermented for several weeks or months in sealed containers.
4. Aging: The fermented liquid is aged in wooden barrels for years, allowing it to develop complexity and flavor.
5. Filtration: The aged lao chou is filtered to remove any impurities.

Types of Lao Chou

Lao chou can vary in flavor and acidity depending on the aging process and the specific microorganisms used. Common types include:

• Young Lao Chou: A light-colored, less acidic lao chou with a mild flavor.
• Aged Lao Chou: A darker, more acidic lao chou with a stronger, more complex flavor.
