I have purchased a few different types of natural peanut butter and all have stated that refrigeration is required after opening. However, I recently purchased Archer's Farms Almond, Peanut & Cashew Butter from Target which doesn't say anything about refrigeration after opening. From what I've read on other sites (anecdotal) and some .edu sites, raw/natural nut butters can grow mold and do require refrigeration. Any ideas on why Archer's Farms butter doesn't say anything about refrigeration?
Peanut butter unopened 6-9 months Refrigeration not needed. Keeps opened 2-3 months longer if refrigerated. Natural peanut butter must be refrigerated after opening.
