How long will freshly rendered lard last?

Under the theory of colder = better when it comes to storage, I've always frozen mine in sealed glass jars (with a working supply in the refrigerator). As an experiment, I've been keeping an unsealed jar in the pantry, inspecting it from time to time whenever I happen across it. It's been in there over 5 years with no detectable changes.

Recently I ran across this story:

If you keep it in glass, in the coldest part of the fridge, and tightly covered, my experience is 6 to 9 months -- IF it lasts that long!

According to what I've read, freshly rendered lard will last up to 3 months in the fridge and 1 year in the freezer.
