The coffee at the office is meant for office use. Don't you think it is kind of like stealing to take it home for your personal use? Or did you mean you will just drink coffee at the office from now on? Coffee grounds are THAT expensive - buy your own at the grocery store.
Shimmysmom, I also didn't notice the taste until just recently.....for example, I had instant coffee packed away for more than 10 years with my Pesach stuff and it always semeed fine to me.
But now, I can tell if chicken and turkey have been frozen, sometimes even by smelling it, not tasting it. And coffee has to be fresh fresh fresh in my book...not just freshly opened, but freshly brewed.
seriously? coffee gets stale? I didnt know that. y don't I taste a difference?
you're either not a coffee maven, or your coffee doesn't hang around long enough to get stale. You should be able to smell the difference, though--if it doesn't smell like anything, it won't taste like anything.
It's not like bakery bread--it doesn't get stale in just a couple of days.
They sell tiny bags of coffee grounds. Why don't you just buy a small bag for your home and replace as needed? Sure, in 10 years coffee will go bad, but coffee can hang around for a few months in its bag/can and still be aromatic and fresh.
Sara, going back to your original question. If you used it for a coffee cake or any other recipe that calls for coffee you probably won't be able to tell whether t'was fresh. I have a delicious coffee cake recipe if you're intersted....
