Shelf life of opened bottle of vinegar

  • 4

I am debating whether to order a 5 liter container of champagne vinegar to save a few bucks, as we have to order it for delivery. It would probably take us a year or so to go through that quantity. Any idea how long a bottle can be open before it deteriorates? or does it??

Thanks

  1. It should be fine. You could also infuse a few smaller bottles with herbs; those would make nice gifts.

    1. I've kept other kinds of vinegar around for over a year without problems. It's already vinegar, after all. If you're worried, you can keep it in the fridge. Assuming you have plenty of extra room ;)

      Though if it were in plastic, I'd be wary of a year of plastic dissolving into the vinegar--but that's just me.

      1. It keeps a long, long time...I kept vinegar in a gallon plastic jug for two years without it going flat or killing me. Dont worry about it.
