The shelf life of homemade walnut milk in the refrigerator can vary based on the freshness of the ingredients used and the storage conditions. Typically, homemade walnut milk will last for about 3 to 4 days when stored properly in the refrigerator.
To maximize its freshness and longevity, follow these tips:
Store in airtight container: Transfer the homemade walnut milk to a clean, airtight container before placing it in the refrigerator. This helps prevent exposure to air and potential contaminants.
Keep at a consistent temperature: Make sure your refrigerator is set at a constant temperature to maintain the freshness of the walnut milk.
Observe signs of spoilage: If you notice any changes in color, texture, or an off smell, it's a sign that the walnut milk may have gone bad, and you should discard it.
Shake before use: Separation is natural in homemade nut milk, so shake the container well before each use to mix the contents.
No preservatives: Homemade walnut milk doesn't contain preservatives like store-bought versions, so it won't stay fresh as long.
Remember that since homemade walnut milk lacks preservatives, it has a shorter shelf life compared to commercial products. If you find that you can't finish the batch within a few days, consider making smaller amounts or freezing portions to extend its usability. When freezing, leave some space at the top of the container to account for expansion as the liquid freezes.
As always, use your best judgment and sensory cues to determine if the walnut milk is still safe to consume after the recommended timeframe.
