Opening never extends a date: if the packet date comes sooner, go by that. Estimates for quality, not a safety ruling. What the dates mean

Peanut butter keeps for about 6 months in the cupboard, counted from when you buy it. That's SnapLarder's estimate for peanut butter in general. If the packet has a date, go by the packet: it's specific to that product.

How long does peanut butter last once opened?

About 3 months. Opening never extends a date: if the date on the packet comes sooner, go by that. Check the label, too: some products need to go in the fridge once opened.

Does peanut butter have a use-by date?

Usually not. Peanut butter normally carries a best-before date, which is about quality rather than safety. Stored as the label says, it’s usually still safe after it, though it may not be at its best. Use by vs best before

Can you freeze peanut butter?

There's no need. Peanut butter already keeps for about 6 months in the cupboard.
