To maintain the quality of your apple cider vinegar and extend its shelf life, store it in a cool, dark place away from direct sunlight. Keep the bottle tightly sealed when not in use.

Now, let's switch to Chinese for the translation.

Vinegar does not expire after certain time, but its quality will certainly deteriorate (most people are not fond of the changes in taste that are occurring) over time (especially after opening the bottle). Sometimes the apple cider vinegar can become cloudy or hazy, but it's still safe to use.
