Quick Answer
Rendered fat typically lasts for 3 to 6 months in the fridge when stored properly in an airtight container. When sealed in a clean glass jar with a tight-fitting lid, it can last up to 6 months. If frozen, it can last indefinitely, but the quality may degrade after a year.
Storing Rendered Fat
When storing rendered fat, it’s essential to ensure the container is clean and dry to prevent contamination. Transfer the fat to a clean glass jar, leaving about 1/4 inch of space at the top. Seal the jar with a tight-fitting lid and label it with the date. Store the jar in the refrigerator at a consistent temperature below 40°F (4°C).
Freezing Rendered Fat
If you plan to store rendered fat for an extended period, consider freezing it. To freeze, let the fat cool completely, then transfer it to an airtight container or freezer bag. Label the container with the date and contents. Frozen rendered fat can be stored for up to a year without significant degradation in quality. When you’re ready to use it, simply thaw the fat in the refrigerator or at room temperature.
Tips for Long-Term Storage
To ensure the quality and safety of your stored rendered fat, keep the following tips in mind. Always check the fat for any signs of spoilage before using it, such as an off smell or slimy texture. If you notice any signs of spoilage, discard the fat immediately. When storing frozen fat, make sure to label the container clearly and store it at 0°F (-18°C) or below to prevent degradation.
