Does Charcoal Go Bad And How To Store It Properly!
Are you a grilling enthusiast or just started grilling curious about the shelf life of your trusty fuel, charcoal? Or perhaps you found an old bag in the shed and are wondering if it’s still good?
The longevity of charcoal is a common concern, especially since it’s not something most people use every day. Contrary to popular belief, charcoal can lose its effectiveness, particularly if stored improperly.
Stick around for a complete low-down on charcoal’s lifespan and how to maximize its shelf life.

DOES CHARCOAL ACTUALLY GO BAD?
Effectiveness Over Time
Charcoal might not have an expiration date, but it does have a ‘best by’ period, so to speak. Over time, charcoal absorbs atmospheric moisture, affecting its lighting efficiency and burning steadiness.
This isn’t a quick process but can certainly impact your grilling game over time.
Moisture Exposure
Moisture is charcoal’s worst enemy. Wet charcoal struggles to catch fire and smolders inefficiently. Worse still, it can emit an unpleasant aroma that could transfer to your grilled food.

Quality Differences
Lump charcoal, made from hardwood, is generally more sensitive to moisture compared to briquettes. Briquettes often contain additives that make them more durable. However, no type of charcoal is completely immune to moisture damage if poorly stored.
HOW LONG CAN YOU KEEP CHARCOAL?
Shelf Life of Unopened Bags
Unopened bags of charcoal can last up to two years if stored in a dry, well-ventilated space. The sealed packaging plays a crucial role in maintaining the charcoal’s efficacy.
Shelf Life of Opened Bags
Once opened, it’s best to use charcoal within six months. Although you may extend this to a year if stored impeccably, don’t expect peak performance.
Factors Affecting Shelf Life
Environmental factors like humidity, temperature, and pests can significantly impact charcoal’s shelf life. For example, storing charcoal in a damp basement will accelerate its degradation.
WHAT MAKES CHARCOAL GO BAD?
Effects of Humidity
Humidity causes charcoal to absorb moisture, leading to poor ignition and temperature instability. The problem amplifies in humid climates or during rainy seasons.
Temperature Changes
Temperature fluctuations result in condensation within the storage area, causing the charcoal to absorb moisture. This creates a vicious cycle of spoilage.
Pest Interference
Believe it or not, pests can affect charcoal, especially those with flavor additives or lighter fluid. They can introduce dampness and contamination, rendering the charcoal less effective.
HOW TO PROPERLY STORE CHARCOAL?
Location Matters
How long your charcoal will last depends a lot on where you keep it. Charcoal should be kept in a cool, dry place like a basement, tool shed, or garage storage box.
High humidity or direct sunlight should be avoided at all costs because they can cause charcoal to soak up water and become less good. If charcoal is wet, it might be hard to light and might grow mold over time.

Signs of Bad Storage
It’s important to check on your charcoal storage often to see if there are any signs that it needs to be fixed.
If the bags have a musty smell, mold grows on them, or there are clear signs of moisture on them, this is a sign that the way they are being stored needs to be changed.
It’s important to find the best place, but it’s also important to protect the environment. Always make sure the place you store things is dry and has good air flow.
Use Desiccants
If you want an extra layer of protection against wetness, you could put desiccants like silica gel packets around the storage area. These materials could change the game when it comes to soaking up extra water.
You can put silica gel packets right in the bag with the charcoal or in the box or cabinet where you keep the charcoal. They help reduce the humidity in the air, which makes your charcoal last longer.
Regular Checks
Make it a habit to check your storage area often to make sure your charcoal stays in good shape. Look for things like water leaks, signs of pests, or places where the temperature changes.
If you take care of these problems right away, your charcoal won’t go bad and stop working. If you find a bad bag, it’s best to use it right away for something less important than keeping it for a big grilling party.

Rotating Stock
Use a ‘first-in, first-out’ approach to keep your charcoal working well. Keep your older bags of charcoal where they are easy to get to so you can use them up first.
This will help you keep a steady supply of fresh charcoal that works well. This not only makes sure that you use the best charcoal first, but also keeps the older bags from breaking down and becoming useless over time.
WHY IS PROPER STORAGE IMPORTANT?
Financial Savings
Charcoal isn’t cheap, especially high-quality varieties. Proper storage methods can extend its life, saving you money over the long term.
Safety Concerns
Charcoal can easily catch fire if it is not stored properly. This is especially true if the charcoal takes in flammable gases.
Grilling Quality
High-quality, properly-stored charcoal generates more heat and maintains a more consistent temperature, resulting in better grilled food.

FINAL THOUGHTS
Charcoal doesn’t exactly “expire,” but it will lose quality over time if not stored properly. You can keep your charcoal in perfect condition for your grilling needs if you know how it reacts to different temperatures and humidity levels and if you store it properly.
FAQS
- Can I revive wet charcoal?It’s tricky and not recommended. Wet charcoal can be a safety risk and diminish your grilling experience.
- What’s the difference between lump charcoal and briquettes in terms of longevity?Lump charcoal is more susceptible to moisture and generally has a shorter shelf life compared to briquettes.
- Can I store charcoal outdoors? It’s risky due to varying temperatures and potential humidity. Always best to store it in a cool, dry place.
