My instant coffee expired three years ago🤔😏can I still drink it.

Probably gonna taste stale as could be. A suggestion though. If you are not an avid coffee drinker and it tends to sit on the shelf for awhile you could get beans instead which stay good for much longer as long as they are seal and in a dry place.. Get yourself a little electric grinder and your good.

It's my experience that sell by dates are usually pretty acurate.

Of course!

Is it just the powder

sure. Instant coffee tastes the same fresh or stale 🤢

Vintage Coffee now

maybe but not after 300

Your insta coffee is like my cum, it expired years ago and I’m hoping someone will drink it

Yes. Coffee instant or otherwise doesn't expire regardless of an arbitrary shelf life posted on the jar.
