As an expert sommelier and brewer, I can confidently say that fresh apple cider does have a limited shelf life. While it may not go bad in the traditional sense, it will eventually start to deteriorate in quality.
Fresh apple cider, especially if it is unpasteurized, is a perishable product that is prone to fermentation. This means that over time, the natural sugars in the cider can begin to ferment, leading to the development of alcohol. While some people may enjoy the taste of slightly fermented cider, it is not ideal for everyone.
Additionally, apple cider is a natural product that contains no preservatives. This means that it is more susceptible to spoilage and bacterial growth compared to other beverages that have preservatives added. Once a bottle of apple cider is opened, it is exposed to the air and can become a breeding ground for bacteria.
To ensure the freshness and quality of fresh apple cider, it is best to consume it within a few days of opening. After that, the taste and texture may start to change, and it may no longer provide the same enjoyable experience. While it may not necessarily be harmful to consume cider that has gone past its prime, it is always better to err on the side of caution and discard any cider that seems off or has a strange smell.
If you find yourself with leftover apple cider that you know you won't be able to finish within a few days, there are a couple of options to consider. One option is to refrigerate the cider, as this will help slow down the fermentation process and extend its shelf life. However, even when refrigerated, fresh apple cider will only last for about 7 to 10 days after opening.
If you want to further extend the shelf life of your opened apple cider, freezing is a good option. To freeze apple cider, it is important to transfer it to an airtight container, leaving at least 1/2 inch of headspace at the top. This is because apple cider will expand when frozen, and without enough room for expansion, the container may burst.
When you're ready to enjoy your frozen cider, simply thaw it in the refrigerator overnight or place it in a bowl of cold water to speed up the process. It is important to note that freezing may slightly alter the texture and taste of the cider, but it will still be safe to consume.
While fresh apple cider does not necessarily go bad, it does have a limited shelf life. To ensure the best quality and taste, it is recommended to consume it within a few days of opening. If you have leftovers, refrigerating or freezing the cider can help extend its shelf life, but it is important to keep in mind the recommended time frames for storage.
