do coffee grounds expire?

post #1 of 21
Thread Starter 
if they're stored in the fridge but have been opened?

is the worst that will happen after a month or so that the flavour will change or do they actually go 'bad'??

i'm pretty sure that they're like ground spices and herbs, they just loose their flavour and go stale. i don't think you'll get coffee poisoning or anything from them. though according to this site the fridge is a bad place to keep them.

The flavor will change noticeably within hours of opening, not a month.

Yes, they most definately go stale. I've never heard of anyone getting food poisoning from ground black coffee so I think you'll be fine there.
Love the post? Why not buy the T-shirt!

Keeping the coffee in the refrigerator is definetely not a good idea. Just make sure the bag is sealed very tightly, and keep it in a cabinet. As long as air isn't hitting it, it shouldn't go bad too fast. And no, old coffee won't harm you, though it will taste horrible, and possibly give you a bad stomache ache.

Yeah, Alton Brown said not to keep coffee in the fridge. I trust Alton Brown. He recommended beans though, not grounds.

Why would "old" coffee give a person a stomach ache? That makes no sense at all. It might be stale but it's not like it's rotten or moldy or growing bacteria...



And I assume we're talking about "Ground Coffee" (coffee beans that are ground but not brewed yet) vs. "coffee grounds" that are left over AFTER one brews coffee...

Why not keep it in the fridge? I keep mine in the freezer.

keeping coffee in the fridge lessens the flavor, and if not sealed properly, your coffee will take on the flavor of anything and everything in the fridge. mm, garlic cofee. I keep my coffee in an air tight container - like a fake tupperware of sorts in a cabinet.

I've never had a problem keeping it in the freezer. I keep it in the can in comes in and everything.

Coffee is best kept in an airtight container, at room temperature. I used to work at a coffee place and that's what we were told to tell our customers.

ground coffee, lol, yes thats what i meant. and yup, i used to work on lygon st (expensive coffee st down here) but we only did espresso. and when i worked at starbucks..well anything over 2 days old was chucked out, all very fresh actually, congrats to starbucks there.

i figure its not too bad, it DOES smell different though but i drank it again this morning and from what i can tell no adverse reactions i was told to put it in the fridge..but i did actually wonder about moisture? oh well.

you live and learn, right? its been in the fridge so long now that it might as well stay there. almost finished anyway ..

You should always grind whole beans fresh for each pot. A small grinder will only cost 10 - 15 bucks. It's a good investment.



Try to find a coffee shop that can tell you how long ago the coffee was roasted as well. You can really taste a difference between fresh roasted and 3 week old coffee.



At the coffee shop I work at, most of our coffees are served within a few days of being roasted. It's a good thing.

ok so i meant to throw it out two days ago JUST in case. but haven't gotten around to it and exhausted this morning and made it absentmindedly and its sitting there steaming and black..im seriously gonna assume that it just tastes different but you can't get like...sick from it.

it doesn't LOOK mouldy..

(and yes, when i worked at starbucks we ground it fresh..tastes amazing. quite temptedto tip this down the sink and go to starbucks for once and buy it. know its fresh. know its good. but such a waste of a mug right here )

hoping the stomach ache thing doesn't happen . its almost 2 months in the fridge now (no...i exagerate...more like 1.5)..... ill let you know, and be the case study

starbucks is a good 10 mins away..

2 months in the fridge is fine. don't worry about it.



the only issue will be the flavor, which will prolly be flat and a bit bitter.



enjoy your coffee. it's not worth getting worked up about.



:coffee smilie:

I have I think ground(?) filter coffee that I've had in the usual standard foily packets waaaaaaay past their sell by date/eat by date, and they're absolutely fine! You can have them years and they'll still be fine, if the packets are closed, until you come to use one! I'm drinking some as I speak!!

Also if you think the taste of your older is not quite what it should be as it would be when new, why not mix some of it 50/50 or so, in with fresh bought coffee (from sealed packets or otherwise) and use up your older coffee that way! Simple yeh ?
