Does apple cider vinegar contain sulfur?

Here's why:

* Ingredients: Apple cider vinegar is primarily made from fermented apples, water, and sometimes yeast. These ingredients do not naturally contain sulfur.

* Production Process: During the fermentation process, yeast converts sugars in the apples to alcohol, then to acetic acid (the main component of vinegar). This process does not introduce sulfur.

* Trace Amounts: While it's possible for trace amounts of sulfur to be present in the apples used to make vinegar, these amounts are negligible and not considered a significant component.

Therefore, you can safely assume that apple cider vinegar does not contain sulfur in any significant amounts.
