Due to its high acidity and self-preserving properties, Kirkland apple cider vinegar technically never expires. While a best-by date is printed on the bottle as a quality guideline, the organic, unfiltered vinegar with the 'mother' can be safely used long past this date, provided it is stored correctly.

While many vinegars begin their life with a yeast-driven fermentation, the finished product can be entirely yeast-free through specific processing. For individuals with yeast sensitivities or dietary preferences, identifying which vinegar does not have yeast is crucial for avoiding adverse reactions.

According to the Canadian Food Inspection Agency, the gelatinous disc or stringy blob found floating in a bottle of vinegar is a completely harmless substance known as "mother of vinegar". This naturally occurring biofilm is a normal byproduct of the fermentation process and can develop even in store-bought vinegar, particularly if it is unfiltered or unpasteurized.

The color of apple cider vinegar (ACV) can range from a pale, clear golden hue to a dark, cloudy amber or brown, depending entirely on its processing. This natural variation is not a sign of spoilage, but rather an indicator of how the product was made and what beneficial compounds it still contains. Understanding these differences helps you select the right ACV for your needs, whether for health benefits or culinary applications.

Apple cider vinegar's high acidity means it rarely spoils, but its quality can change over time. Here's how to tell if raw apple cider vinegar is bad by checking for unusual odors, tastes, or contamination, and distinguishing normal aging from true spoilage.
