# Does Ground coffee expire?

**Does Ground coffee expire?: Safe for a long time, good for a short one. Grinding multiplies the surface area and staling takes days, not weeks.**

Best within 1-2 weeks of grinding; sealed vacuum packs hold for months

Whole beans protect their own aromatics; grinding exposes all of it at once, which is why ground coffee loses in a week what beans lose in a month. A vacuum-sealed pack keeps until it is opened, and then the same clock starts. None of this is a safety question — old coffee is stale, not harmful. If you have a grinder, buying beans is the single change that makes the largest difference.

## How to store it

- Airtight, opaque, room temperature.
- Freeze in small sealed portions if you must keep it a long time.

## How to tell it has gone

- A cardboard or flat taste, and no bloom when brewing.

> "Use by" and "best before" are legally different. Use-by is a safety date and should be respected; best-before is about quality, and food is usually fine well past it. Where the two diverge matters, the page above says which applies.
