Here’s the thing: charcoal is a sponge. Not literally—don’t try to clean a spill with it—but it loves to suck up humidity from the air. That’s why a bag left open in a damp garage becomes a sad, crumbly mess. Old charcoal doesn’t catch fire easily, and when it does, it burns at a lower temperature.
Ever tried to grill a steak on charcoal that’s been sitting around for two years? You get a gentle, lukewarm whisper of heat instead of a roaring sear. Your steak ends up looking like it got a sunburn through a window—all sad and grey. Not the vibe.
How to tell if your charcoal is past its prime
Your first clue is smell. Fresh charcoal has a neutral, almost clean scent. Old, moisture-stricken charcoal often smells like a damp basement or, worse, like the inside of a old fridge. If you get a whiff of mustiness, it’s a red flag.
Next, touch it. Does it crumble like a wet cookie when you squeeze it? Yeah, that’s bad. Good charcoal should be firm and make a satisfying clink sound when you drop it. If it sounds like a marshmallow hitting a pillow, you’ve got a problem.
Finally, check for ash. If the bag is full of fine black dust at the bottom, the briquettes have basically self-destructed. That dust won’t burn—it just smothers the fire and makes you cough.
