I have a tub of duck fat in my fridge that I love cooking with. I bought it frozen at a local organic grocery, but there's no expiration date on it.

Any idea how long this stuff keeps while refrigerated?

Because there are no guarantees on impurities, I think you are right to store it in the fridge. Mine has kept fine for 3-6 months in the fridge, up to a year in the freezer. No problems, no rancidity. Use clean (clean!) spoons to scoop it out, that will prevent contamination which could attract mold spores.

Ditto, I rendered some duck fat from trimmings from a duck and keep it covered air tight in the fridge and several weeks later it seems fine. Fats can go rancid without smelling bad but this duck fat is just as white and pure looking as the day I rendered it. I also render lard and keep it for weeks.

I have a jar of duck on my counter (not in the fridge) which I have been using for several weeks and it is fine. I am sure that, in the fridge, it will last for a couple of months - provided that it is lidded and not near anything with a strong smell which would taint it.

I always keep the jar of fat which I am using beside my cooker, and jars of rendered fat to use in the future in the fridge.I have never had one go rancid yet.
