The only ingredients on the label are “peanuts, salt.”
We keep peanuts unrefrigerated in the pantry… we keep salt unrefrigerated in the pantry… so how come when you mash them together it makes something that (according to the jar) must be refrigerated after opening?
P.S. I put “good” in quotes because all peanut butter is good. What I mean by “good” peanut butter is the healthier stuff that you have to mix the oil back into and there are only the above mentioned ingredients.

Because the typical peanut butter you have that doesn’t have to be refrigerated has extra preservatives and hydrogenated oils in it that help inhibit bacteria growth.
That all natural peanut butter that is just ground peanuts and salt does not have that, so the oils in that peanut butter can go rancid.
It only needs to be refrigerated to prevent the oil from separating. If you don’t mind stirring it up each time, then you can keep it at room temperature (that’s what I do).

Depending how hot your kitchen cupboard gets in summer, good peanut butter separates & the oil can get rancid.

What kind of peanut butter are we talking about? Here in Australia it’s “Never oily and never dry”.
It doesn’t. I store peanut butter (just peanuts and salt) upside down on the pantry so the oils don’t just all accumulate at the top. Works fine. The jars here don’t say to refrigerate it though haha, strange!!
My peanut butter of choice is Fix and Fogg and I’m yet to try a better brand. I also go through a large jar in less than a month so I’m not worried about it going rancid.
