 How long can you store peanut butter for?

If its unopened, what is the real shelf life of this stuff?
It seems to last forever in my house, but I wonder how long I could really keep it.
Its high calorie, high protein, and high fat content...which for a survival food is perfect.
It packs a lot of calories in a small container, seems to last for a long time, and you can keep a lot on hand in a small space.

Its also cheap.

Thoughts on having this on hand as a 'bunker' item?

if kept cool and un opened it will last for a long time, but it is low in protien compared to other dryed legumes,is high in fat, and ev olive oil lasts longer and is better for you,

From various websites, I obtained the following information: For best long-term storage of peanut butter, buy it in #10 double-enameled cans or buy peanut butter powder (shelf life 7-15 years). I just may have to buy some peanut butter powder to try it out!

Shoot, bad timing on the question. Just two or three weeks ago I think I threw out a container of store brand peanut butter dated 1999. I'm not 100% sure I threw it out, partly because normally I'd test it out just because, so if it turns up somewhere in the basement I'll post the results.

I think the containers are usually "best by" dated for 12 months, or even 18 months. If kept in a cool dark place, they're probably still okay for a year or so after that, but the oil will start going rancid even if it smells alright. Slightly rancid oil is better than no oil in an emergency, but better to avoid it if you have a choice.

Packs very nicely in the back of a fridge...should keep for decades.

I have yet to run into an unopened jar of it that was bad, even after five plus years in our pantry.

We have a chest freezer in the garage that has a small drawer on the bottom that keeps stuff mostly frozen (i.e every frozen item I put in comes out freezer burned after a week). My train of thought is stuff it full of peanut butter. My concern is that if it is un freezing/refreezing, then maybe it will damage the integrity of the peanut butter/container. My rebuttal to myself is that the peanut butter is dense enough that it shouldn't defrost and refreeze as easily as the bag of corn that was in there before. Does anyone know if this would be a good idea? I hate to let the drawer sit empty, and would like it to be used to prolong the life of some sort of prep; plus, I am truly afraid of running out of peanut butter.

I have 3-4 jars in the fridge lined up for use. Fridge might be better than cabinet for longterm storage.

I've eaten PB 2 years beyond the expiration date and didn't even notice.

I keep some around. The oil is critical part, if it gets rancid. I have noticed flavor change with some older pnut butter, but it was still edible. I never have stored it in the fridge, guess I could try that.
the jar I am using now is from last year

In 1982 I ate a c-rat from WWII which contained peanut butter in a can. No problems.
