Is it still vacuum packed? If yes, then I would try it.
You are pouring boiling water through it.
If it does not taste good then you can throw it out or compost it.

Probably OK, open the canister and smell it. It it doesn’t smell like coffee—i.e. it smells acidic or mildewy, then dump it. Otherwise, have at it.

In a sealed plastic container, it probably was not vacuum sealed and will thus be stale. But I agree with @LuckyGuy & @elbanditoroso there’s no harm in taste testing. It won’t harbor any poisons that will survive the brewing process.

Yeah, it should be safe as long as it doesn’t smell like mildew, but bleh, why would you want to brew six year old coffee? shudder

Most likely yes as others have explained, however, I’d ask WHY, are you so coffee deprived that a 6 yr.old canister of petrified coffee is that important to use? lol

Will it kill you? Probably not.

Will it taste of coffee? Probably not.

Personally, I think it would make a lovely addition to my compost. Unless I am digging up a cache in the frozen tundra and well above the Arctic or Antarctic circles, I would skip drinking it.

…unused coffee in plastic… My intuition is that whole bean coffee would be okay to brew, but if it’s ground coffee I’d toss it – unless the quantity is large enough to pose an economic issue. Justification: When you grind up beans the already-large surface area increases by a huge factor, enhancing its ability to absorb chemicals (bad flavors, plastic BPA toxins, etc). Meanwhile the “micro-terrain” of the grind is more conducive to growth of mold & other microorganisms which, even if it doesn’t make you sick, might alter the flavor. No doubt temperature & humidity play a role, cool & dry being best. So much for theory & hypothesis.

Might I suggest you brew a cup & take a sip? A little field research lol. Cue spit take…

@randybowls By all means, if you do test, post the results.
