It depends on storage conditions, but theoretically it can easily be stored for many years. Balsamic vinegars are aged in wood casks for many years (for the best traditional varieties from Modema, Italy) which are not completely sealed so evaporation occurs. This means that balsamic vinegar can be kept safely for many months, even years, after opening on the shelf or in the refrigerator.
All vinegars should be stored in a cool dry place. Such as a cabinet or pantry.
You technically could not refridgerate balsamic vinegar but I highly recommend it.
