Can I drink Max House original roast expire coffee?
However, sometimes it just can't be helped, so in those instances, I hope that this information will be of use to you. I can't honestly tell you what the coffee expiration date is as this isn't a hard science. And the coffee best buy date or the coffee use by date that you find on the bag of coffee beans is the manufacturers estimate of how long coffee will stay at it's peak flavor. So that really doesn't tell you much.
Now personally, I have enjoyed expired coffee that was a year and a couple of days past the coffee expiry date on the bag. Now these were vacuum sealed bags and they were dark roasted coffee beans. They tasted fine. Not as good as fresh batch of roasted coffee, but you wouldn't expect them to be would you? Now if you're going to do this, make sure their is no mold or any other obvious signs of funkiness on the expired coffee. Now when it comes to expired ground coffee, I usually won't drink expired ground coffee that is older than 3 or 4 months. But then again, you want to make sure that the coffee looks fine and living in a dry climate certainly lengthens the expiry date as compared to a moist climate.
Bottom line is to enjoy as freshly roasted coffee as you can and when ground, enjoy your coffee beans within a week is the best practice. This way you'll never have to worry about it.
