Does Coffee go off?

Does Coffee go off?

If you’ve found an old bag of coffee beans or a forgotten jar of instant coffee at the back of the cupboard, you might be wondering — does coffee go off? While coffee doesn’t typically spoil like milk or bread, it can lose its flavour, aroma, and freshness over time.

Let’s explore how long coffee lasts, how to spot when it’s gone stale, and how to store it for maximum freshness.

Does Coffee Expire or Go Off?

Coffee doesn’t go off in the same way perishable foods do, but it does deteriorate gradually. The natural oils inside coffee beans oxidise after roasting, which affects the taste and aroma.

Technically, coffee is safe to drink even past its “best before” date — it just won’t taste as fresh.

  • Whole beans: Last around 6–9 months unopened, and up to 6 months after opening.

  • Ground coffee: Best within 3–5 months unopened, and 4–6 weeks once opened.

  • Instant coffee: Can last up to two years if kept sealed and dry.

For the freshest flavour, buy freshly roasted coffee beans like our House Blend Coffee or Forte Blend Coffee.

Does Instant Coffee Go Off?

Instant coffee has an impressively long shelf life. Because it’s freeze-dried or spray-dried, it contains very little moisture, which helps prevent spoilage.

However, if your instant coffee develops a strange smell or clumps together, it’s a sign that moisture or air exposure has affected it. It won’t harm you, but it might taste dull or slightly stale.

To keep instant coffee at its best:

  • Store in a cool, dry place.

  • Avoid direct sunlight.

  • Reseal tightly after every use.

Does Camp Coffee Go Off?

Camp Coffee — the syrupy coffee-and-chicory essence — lasts much longer than ground coffee, thanks to its sugar and preservative content. Once opened, it’s best used within 6 months, though it can often last longer if stored correctly.

Always check for:

  • Changes in smell or colour

  • A crystallised texture around the bottle rim

  • Unusual separation in the liquid

If any of these appear, it’s best to replace it.

How to Tell If Coffee Has Gone Off

You can usually tell if coffee is past its best by using your senses:

  • Smell: Stale coffee smells flat or musty instead of aromatic.

  • Taste: It might taste bitter, sour, or dull.

  • Appearance: Ground coffee may clump together or appear slightly oily.

If your coffee’s lost its punch, it won’t make you ill — it just won’t deliver that satisfying flavour you expect from a fresh brew.

Try switching to freshly roasted, medium blends such as Royal Blend Coffee or Excellence Blend Coffee for a full-bodied, fresh taste.

How Long Does Coffee Last?

Type of Coffee Unopened Shelf Life After Opening
Whole Beans 6–9 months Up to 6 months
Ground Coffee 3–5 months 4–6 weeks
Instant Coffee Up to 2 years 12–18 months
Camp Coffee 1–2 years ~6 months after opening

How to Store Coffee Properly

To keep your coffee fresh for as long as possible:

  1. Use an airtight container — oxygen is coffee’s enemy.

  2. Keep it cool and dark — avoid sunlight, heat, and moisture.

  3. Buy smaller quantities — fresh is best.

If you love experimenting with flavours, explore our Assorted Flavoured Blend Coffee range for variety that always tastes fresh.

Can You Drink Expired Coffee?

Yes — but it might not taste pleasant. Old coffee isn’t dangerous unless it’s grown mould from moisture exposure. If it smells musty or has visible growth, throw it away.

Otherwise, it’s safe — just not very enjoyable. You’ll notice the biggest drop in flavour and aroma rather than safety.

Freshness Matters

Freshness has a direct impact on flavour. The moment coffee is roasted or ground, the clock starts ticking.

That’s why our range — including the smooth JBM Blend Coffee and bold Italian Blend Coffee — is roasted and packed for maximum freshness.
