  1. Are there any signs of mold?
    If yes, throw them in the trash.
    If not, throw them in your favorite coffee maker. Coffee grounds don’t expire. They do start to lose some flavor if they are sitting around for too long.
    If you use them for a pot of coffee and the coffee is flat, you can throw them out or use them in your garden mulch pile.

  2. If they stink toss them into your compost bin if you use one or just throw them away. Rancidity is not good tasting or smelling. If they smell ok, maybe a little stale and with a dull appearance, mix them 50–50 with new, fresh beans and grind and use them. See how that tastes to you. If you think you are tasting them and it is objectionable then reduce the mix to 25–75. If you are a purist you can just toss them but most people would not know the true taste of fresh coffee anyway as most everything in the distribution system is partly aged especially the beans sitting open in bins (oxidating) or the bags which were not nitrogen flushed (and frankly even those that were deteriorate over time). Unless you are used to drinking coffee that is straight out of the roaster and cooled then immediately ground and brewed (a minimum number of people) you likely dont have a true taste profile for fresh coffee. I used to be spoiled in that I not only got fresh coffee roasted ouside my office door (max 15 yards away) but also my personal blend and roast level (20 Sumatra, 25 Kona, 20 Costa Rican 20 Moka 15 Columbian at a 18% shrink roast) but I controlled the grind depending on my brewer that day. I still blend my own but i stopped home roasting and just work off small batches ordered. It is not as good but frankly neither are my taste buds. Try to act objectively and see how it goes.

  4. Make coffee.
    Unless there are signs of mold or other issues the coffee is still usable. The flavor may not be as full as when they were fresh but unless you are serving a coffee sommelier, it is not likely that anyone will notice.
