Making Kimchi: How Long to Ferment Kimchi

Step 1

Remove the lid from the jar (set a paper towel over the lid first, in case the kimchi bubbles out).

Step 2

Set the lid loosely on top of the jar so air can escape

Step 3

Set the jar of kimchi on a baking sheet or in the sink, in case it bubbles over while fermenting.

Step 4

Let the jar sit at room temperature anywhere from 2 to 8 hours, depending on how sour you want it. Every few hours, smell and taste the kimchi.

Step 5

When it's at a level of sourness you like, tighten the lid and place the jar in the refrigerator.
