How Long Is Apple Juice Good After Opening?

Once opened, the shelf life of apple juice depends on how it is stored and whether it is pasteurized. Generally, pasteurized apple juice, which is the most common type, can last in the refrigerator for about 7 to 10 days after opening. The cool temperature slows down the growth of bacteria and maintains the juice's quality. For apple juice that is not pasteurized or is freshly squeezed, the window for safe consumption is shorter, typically within 3 to 5 days, due to the absence of preservatives and the higher likelihood of bacterial growth. It's important to keep the juice tightly sealed in its original container or in an airtight bottle to prevent contamination and preserve freshness. Signs of spoilage include an off smell, changes in color, or the presence of mold, at which point the juice should be discarded to avoid foodborne illness. For longer storage, apple juice can be frozen, extending its life significantly, though it's best consumed within 8 to 12 months for optimal flavor and quality. Always check the label for specific storage instructions and expiration dates as they can vary based on brand and processing methods.
