You’ll also find starter-friendly recipes, practical tips, and real-life stories from kimchi enthusiasts.

The History and Culture of Korean Fermentation

Why Fermentation Is a Cornerstone of Korean Cuisine

Fermentation in Korea isn’t just about preserving food—it’s about honouring the seasons, connecting with family, and building deep flavours that develop over time. Kimjang, the communal act of making kimchi, is even recognised by UNESCO as an Intangible Cultural Heritage of Humanity.

Historically, fermentation allowed Koreans to store vegetables through long, harsh winters. Today, it remains a daily staple and an expression of identity.

The Science Behind the Flavour

Kimchi is a lactic acid fermentation. Beneficial bacteria like Lactobacillus plantarum break down sugars into acids, creating that familiar sour note while also enhancing digestibility and nutrient availability.

Health benefits include:

• Gut flora support
• Anti-inflammatory compounds
• Rich sources of vitamins A, B, and C

Common Kimchi-Making Ingredients and Substitutes

Tools You’ll Need for Home Fermenting

• Ceramic or glass fermentation crock or jar
• Sea salt (non-iodised)
• Cloth or airlock lid
• Gloves (to avoid chilli burn)

Tips for First-Time Fermenters

1. Use fresh vegetables—organic if possible.
