Have you bought some kimchi and noticed it fizzing, bubbling up, and even popping out of the jar as you opened it up? This probably left you asking, 'is store-bought kimchi supposed to fizz and bubble when you open it?' or 'why is kimchi fizzy?'
The answer is 'Yes'; it is totally normal for unopened kimchi to be fizzy and bubble after opening a jar for the first time.
Why is Kimchi Fizzy? What causes the fizziness in kimchi?
Kimchi is a fermented food, and fermentation involves microorganisms, such as yeast and bacteria, enzymatically breaking down carbohydrates to produce carbon dioxide, organic acids, or alcohol.
The buildup of carbon dioxide is what causes the fizziness in kimchi and your tongue to tingly when you take a bite.
However, that does not mean that every jar of kimchi will be fizzy. Some jars will be flat, which is fine. It depends on how active the fermentation is and what stage it is in when you open the jar. Either way, fizzy or flat, the kimchi is good.
Kimchi is a fermented food that will build pressure inside the jar during the fermentation process. When opened, the pressure from CO2 buildup is released. It is a normal part of natural fermentation, which results in the bubbles making their way to the surface, causing a fizzy or tingly effect.
Is fizzy kimchi bad?
No, that fizzy sensation in kimchi is a good sign that kimchi is ready to eat.
Taking a bite of well-fermented kimchi can remind you of the sensation of eating Pop-Rocks. Remember those fun packets of candies from the 80s? Blueberry Razz was my favorite!
The buildup of gas bubbles is the result of successful fermentation.
So do not toss out kimchi just because it is fizzy. Eat it up!

How to Stop The Fizziness in Kimchi
Now, if you can't bring yourself to enjoy tingly or fizzy kimchi, there are several ways to prevent or stop the fizzy sensation of kimchi.
1. Let the Kimchi Rest
Place the kimchi on a plate for about 15 minutes before eating to dissipate the bubbles or fizz.
2. Burb Kimchi Regularly
Whether you have a jar of store-bought kimchi or you made your own. Be sure to burb it every few days to release the gas buildup from the CO2. Burping a jar of kimchi will help keep the fizzy effect at bay and prevent the jar from exploding.
3. Cook Kimchi
Cooking kimchi with your favorite dish will help remove the fizziness.
4. Ferment Kimchi for a Shorter Duration
If you have ever searched online for a 'kimchi recipe,' you know there are many different ingredients, methods, and suggested lengths of fermentation for making homemade kimchi.
Some kimchi recipes suggest leaving the kimchi on the counter for 1 -2 days. At the same time, others suggest fermenting in an airtight container for 4 -5 weeks or even a year. It all depends on your preference.
However, If you want to prevent the fizzy effect in kimchi, you should do a very short ferment by letting it sit on the counter for one night and promptly store it in the refrigerator.
5. Ferment in the Refridgerator
Due to the cooler temperature, the fermentation process will continue but extremely slowly.
The lid on my kimchi is bulging, is that normal?
A bulging lid on a kimchi jar is a common sign of good kimchi.
The bulging lid happens as the kimchi ferments and the gasses create pressure, pushing the top up.
Be careful opening a jar of kimchi that has a bulging lid. Start by slowly opening the lid, ensuring it is over a bowl or in the kitchen sink. You might even want to do it outside.
Why is my kimchi not fizzing?
If your kimchi is not fizzing to your liking, let it sit out at room temperature to ferment longer. The longer the kimchi ferments, the more bubbling, and fizzing will occur.
How to Tell if Kimchi is Bad
The tell-tale sign of bad kimchi is mold, as in a white film growing on the top of the jar or top layer of the kimchi.
The smell is the next big sign for determining if kimchi has gone bad.
Now kimchi is famous for its 'foul odor,' but this odor will make your stomach turn.
There is a difference; your senses will tell you when kimchi has gone bad and you should toss it out.
