Does Instant coffee expire?
Does Instant coffee expire?
It keeps for years unopened. Moisture is the only real enemy — it clumps and then it tastes of nothing.
Unopened: 2-20 years depending on packaging. Opened: 6-12 months for flavour
Freeze-dried coffee has almost no water in it, and a sealed jar is essentially inert, which is why it turns up in emergency ration packs. Once opened, it takes up humidity from the air, and damp granules clump, dissolve poorly and lose aroma quickly. It never becomes unsafe. Keeping the jar closed and away from steam is the whole of the storage advice.
How to store it
- Airtight jar, away from the kettle.
- Use a dry spoon.
How to tell it has gone
- Hard clumps mean moisture. A weak, papery smell means the aroma has gone.
"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.
