Fermenting Kimchi
Kimchi fermentation conditions are crucial for producing the desired flavors and textures. Here are the key factors:
Temperature: Kimchi ferments best at temperatures between 65°F to 70°F. Cooler temperatures slow down fermentation, while warmer temperatures can speed it up but might result in overly sour kimchi.
Salt: Salt is essential for drawing out moisture from the vegetables and creating an environment conducive to fermentation. The salt concentration in the kimchi brine is typically around 2-3%.
Time: Fermentation time can vary depending on factors such as temperature and personal preference for taste. Typically, kimchi is fermented for 1 to 5 days at room temperature, but it can be left longer for a more intense flavor.
Anaerobic Environment: Fermentation should occur in an anaerobic environment, meaning it should be sealed tightly to prevent exposure to air. This can be achieved using airtight containers like glass jars or fermentation crocks.
pH Level: Monitoring pH levels during fermentation is important for safety and quality. The desired pH range for properly fermented kimchi is typically below pH 3.7.
Ingredients: The ingredients used in kimchi, such as Napa cabbage, radish, garlic, ginger, and chili pepper flakes, contain natural microorganisms that contribute to the fermentation process.
Fermentation Vessel: Choosing the right fermentation vessel is essential. Porous materials like clay pots allow gas exchange during fermentation, while glass jars or food-grade plastic containers are suitable for anaerobic fermentation.
It's important to regularly monitor the kimchi during fermentation. Once fermentation is complete, store the kimchi in the refrigerator to slow down further fermentation.
We use airlock method involves creating an anaerobic environment that allows gases produced during fermentation to escape while preventing air from entering.
We ferment our kimchi in fermentation room at Fork Food Lab. It is temperature and moisture-controlled room which allows us to ferment our kimchi safely.
Now enjoy our delicious kimchi!
