Why Is This Happening ? Dumbfounded By This .

[dieseldick]

i buy coffee , usually egberts mild coffee ,not rich blend. so the granules are a light caramel colour right ? so i put them into a coffee jar , ceramic jar ive had for years, after about 1 week the coffee grnaules start to stick to bottom, go darker in colour and taste not the same as first bought , they actually taste stronger/richer. i was wondering why this is happening, it never happened before. no holes or cracks in the ceramic jar at all. i thought water vapour from nearby kettle getting into jar but dont htink so....

no big deal, just asking n curious

Dont have any ideas. I have never taken coffee out of the jar I have bought it in. Not sure why you would do that.

I recant my coffee from the jar to my coffee canister. But never known the coffee to change colour etc.

sounds as though there's some moisture got in from somewhere if the granules have gone sticky -(wet spoon maybe/cannister not dried thoroughly and this may have affected the colour but have no idea why.

Its simple...the jar that you decant the coffee into is not as airtight as you thought.

Even if you leave coffee in the shop jar, this can happen after a wile, as my experiences with my caravan in Cornwall shows.

Instant coffee is very susceptible to the smallest amount of moisture...its the same with gravy granules and other types of things.

Leave the coffee in the shop jar from now on !

Yes, Mikey4444 is spot on. The most common type of coffee this happens to is usually the "gold" type which are freeze-dried. I've had it happen to Gold Blend and the Aldi equivalent. Your Douwe Egberts mild is freeze dried.

As Mikey says, don't decant it into another container and make sure the lid on the jar is screwed tight at all times.

All of these instant granulated foodstuff are whats called anhydrous, ie no water which means that any tiny amounts of water vapour will be absorbed by the foodstuff instantly

Your coffee canister is manky, wash and dry thoroughly.
