Peanut butter - what am I doing wrong?

[rebeccaC]

Oh good, mine's coming out of the refrigerator. I just remember reading the "refrigerate after opening" label and never questioned why.

refrigeration is about the oil separation especially in all natural peanut butter and the possibility of the oil going rancid. That takes awhile. It's not about aflatoxins. I don't refrigerate mine but i finish a jar within a month when i have it around. If I wasn't finishing it within a month or so or lived in a hot or humid area I personally would refrigerate it after opening.
