What happens when apple cider goes bad?

Answered by Dustin Gorski

When apple goes bad, several changes occur in its appearance, taste, and overall quality. As an expert sommelier and brewer, I have encountered situations where apple cider has gone bad, and I can provide you with a detailed explanation of what happens during this process.

1. Appearance: One of the first signs that apple cider is going bad is a change in color. The cider will become darker, often taking on a murky or cloudy appearance. This change in color is due to the fermentation process that occurs when the cider spoils. Additionally, you may notice that the cider starts to froth or develop bubbles. This is a result of the converting the sugars in the cider into and carbon dioxide.

2. Taste: As apple cider goes bad, its taste undergoes a significant transformation. Initially, you may notice a slight sourness, similar to vinegar. This sourness is a result of acetic acid production during fermentation. The longer the cider ferments, the more pronounced this sour taste becomes. Eventually, the cider may become unpleasantly sour and vinegar-like, making it unpalatable for most people.

3. Quality: When apple cider goes bad, its overall quality deteriorates. The fermentation process not only alters the taste but also affects the texture and aroma of the cider. The frothing and carbonation can make the cider appear fizzy, which is not desirable in traditional apple cider. Additionally, the cider may lose its fruity aroma and develop a more pungent, fermented odor.

It is important to note that while spoiled apple cider may taste unpleasant and have a higher alcohol content, it is not harmful to consume in moderate amounts. However, due to its unappealing taste, most people prefer to discard it rather than consume it.

To prevent apple cider from going bad, proper storage is crucial. Keep the cider refrigerated at all times, as cold temperatures inhibit the fermentation process. Additionally, ensure that the cider is stored in an airtight container to prevent exposure to oxygen, which can accelerate spoilage.

When apple cider goes bad, it undergoes fermentation, resulting in changes in color, taste, and overall quality. The cider becomes darker, froths, and develops a sour taste similar to vinegar. While it is not harmful to consume, most people find the taste unpleasant and choose to discard it. Proper storage in cold temperatures and airtight containers can help prevent apple cider from spoiling prematurely.
