As the question states, is kimchi still safe to eat after spending a few hours unrefrigerated, the time it takes me to get home ?

I'm mostly concerned because my commute home involves time in a heated bus

    shouldn't you be asking if the other bus passengers are safe from the kimchi? I see the headlines now: explosive event rocks commuters...

I make kimchi regularly. It sits on a shelf at room temperature for a week or more, and slowly ferments. Some people ferment it for months. Sure, it likes a low oxygen partial pressure, but a few hours on a bus isn't going to hurt it.


Kimchi existed long before refrigeration. Infact the sole principle of kimchi is preservation through fermentation. So yes, you can leave it at room temperature for a few hours.

    primary principle perhaps. umami heaven should also get a salute.
