  • First of all, you’d better store it in the original bottle. Seal it tightly and place it in a cool and dark place. A pantry would be a great choice!
  • Make sure that the temperature there is always constant since soy product is quite sensitive to its fluctuations.
  • Remove the bottle away from the stove or dishwasher to avoid any extra heat.
  • Once we open the bottle, it becomes vulnerable since bacteria may get inside easily. To prevent this, remove the dressing to the fridge. That is why, when people ask “does soy sauce need to be refrigerated?” we strongly recommend doing so. If we refrigerate soy sauce, it will lose its qualities much slower.

Does soy sauce go bad if not refrigerated? Well, it won’t get rotten in the blink of an eye, of course, but the lifespan of the product will be significantly reduced.

It seems very simple but these life hacks can save the product from the untimely spoilage.

Sooner or later, a question occurs whether freezing is OK for the soy sauce. 

We must disappoint you guys but this product won’t get solid in the normal freezing camera. 

All because of the high content of salt in it which prevents the liquid from hardening.

So what will happen is that the sauce will become extremely cold but that’s it.

However, if being put to the camera at a lower temperature, the sauce may probably freeze.

Those who don’t consume soy sauce regularly often become confused when thinking about the storage of the dressing.

What is the shelf life of soy sauce, they ask? 

Well, as usual, everything hangs upon how and where we keep it, also, sealing or unsealing the bottle plays a big role.

Even though this exotic dressing is so long-lasting and it’s not so demanding as other products may appear to be, soy sauce, like teriyaki sauce, does indeed get spoiled with time.

Improper storage conditions are among the common reasons why this happens.

How to tell if soy sauce is bad?

The most obvious sign is a mold. When noticing any traces of soy sauce mold inside the bottle, discard it instantly since the product is irrevocably bad. 

However, it is useful to note that old soy sauce may change its color and odor but it won’t mean that it’s bad. 

If, after a certain period of storage, its color darkens and the smell becomes stronger, be calm. The sauce is still OK, it’s just getting older!
