is it safe to use unbrewed coffee years past its shelf life
Coffee begins to loose its flavour after it is ground, so it is best to grind the beans just before you will brew it. The longer ground coffee sits around exposed to the air the faster it becomes stale. Coffee companies want you to enjoy their coffee at it's best flavour, so they put an expiration date on it. This way you will want to brew it and drink it while it still has it's best flavour. So it is safe to drink, although it might not be at its best. Source(s): midnight Â· 7 years ago.
