                                Vinegar has an almost indefinite shelf life due to its high acidity, a natural preservative that inhibits microbial growth. This self-preserving nature directly addresses the common kitchen question: **can you leave apple cider vinegar out overnight?** The answer is that it's perfectly safe, and a night on the counter will not cause spoilage.
