Our nut butters are stone-ground with no added preservatives, so your Revival Food Co. jar won't outlast that jar of Jiffy that you've had in your pantry is 1989. That being said.... the fresh enzymes in the nut butter will start to break down after about a year (but I'm sure it won't last in your pantry that long anyways). The consistency is best at room temperature, and the almond butter will stay fresh due to the high oil content of the almonds and coconut oil, as well as the preservative qualities of the pink Himalayan sea salt. If the oil starts to separate (it will, if you don't touch it for about 2 weeks), then just flip it over onto the lid for a day to allow the oils to gently mix back in. Voila!
