How long is apple cider vinegar good for?

Even wine goes bad...so there is a flaw in your theory...throw that sucker out....besides,,,vinegar is cheap...I'll tell you what it wil do...put it in a bucket or bowl...throw in your tarnished, brass metal thingies...say old drawers handles or pennies,,that sort of thing....let it sit overnight and then just wash with a rag and soap and water the next day...willl gleam like you wouldn't believe...

Apple Cider Vinegar is actually more of a cleanser, but doesn't remove excess water (wrong type of cleanse). There are some herbs like Yellow Sweet Clover, Bucku Leaf, and Parsley Leaf among others that can help to promote lymphatic drainage, which can help to reduce water retention and kind of even out the excess water in your system naturally and safely. Granted, if you don't want to take herbs or supplements, you could try a lymphatic massage to help move the fluid around and help to get it out of your system. Good luck and I hope I helped!

Perhaps forever, if sealed (or tightly resealed). In glass, not plastic.

I have some glass bottles of cider (and other) vinegars at our vacation cottage which I originally purchased over 30 years ago

that have not been fully used up yet, and they are still good. But I have noticed that other vinegars packaged in plastic bottles that we similarly used up slowly started to spoil after a couple of years, taking on the taste of the plastic.

I believe I have read of instances of vinegar discovered in and recovered from submerged ancient Roman, Greek and Phoenician shipwrecks that was still perfectly good.

Suggestion:any vinegar from apples should be kept in the fridge.

Discover yourself if you still like the taste after some time:it gets more bite and sometimes it gets bitter.Not better.

THROW THE OLD ONE OUT.HORRIBLE TASTE.

You might not want to use it for cooking, but you can still use it to scrub the sink or toilet. Make a paste with baking soda or pour the vinegar and baking soda into the toilet.

Vinegar can actually turn bad -- it starts smelling more like paint thinner and the taste isn't so great either.

It gets a sediment in the bottom when it's old, and the flavor gets very strong and bitter over time, due to evaporation. I'd suggest you throw it away.

Just about forever, but there is an old adage that says, "When in doubt, throw it out"

it's not getting old !

JUST-BETTER !

make a little-vinegrette and taste-it !

aged vinager is best--look at the balsamic!!!

i suggest you throw it out & buy new if theres no need for it now then dont replace it.
