We stored our homemade duck fat drippings in the fridge at approximately 40°F (4°C) and held both opened and unopened samples for 60 days. During this period, we closely monitored the drippings for any signs of spoilage. We noted a slight change in color from a rich golden hue to a duller shade in one opened sample, and we detected a faint rancid smell that was absent in the unopened sample. The texture remained consistent, with no signs of mold growth. After a quick cook test, heating the drippings to 165°F (74°C) for verification, we ultimately decided to discard anything that appeared questionable to ensure safety.
The expiration date for duck fat drippings is more about food safety rather than quality.

When reheating duck fat drippings, do so gently over low heat to preserve their flavor and prevent them from burning.
