What is charcoal?

Charcoal is a type of fuel made from burning wood, coal, or other organic materials in an oxygen-deprived environment. It is mostly used for grilling and barbecuing, but it can also be used for heating and lighting purposes.

To ensure your charcoal has a long lifespan, it’s essential to keep it dry. Moisture can cause the fuel source to become ineffective, making lighting an issue and lowering its heat output.

To protect against any moisture getting in your charcoal, store them in a sealed container or use humidity absorbers. This will not only maintain the quality of your product but also maximize its performance when you need them most!

Charcoal is not perishable and will last for many years, unlike food and other organic materials that can spoil or become brittle. In fact, if stored properly, charcoal can last indefinitely.

Charcoal that takes in moisture can be difficult to light and will produce less heat due to excess water filling the pores. This makes it unable to burn as efficiently, resulting in potential problems for your grill or other equipment like extra smoke production or even damage.

Many people mistakenly believe that charcoal comes with an expiration date when in actuality, it can last forever, provided that you store and keep it dry! Storing your charcoal properly is the key to making sure you get every penny out of each bag.

Nevertheless, the efficacy of charcoal may dwindle over time as it is exposed to air and sunlight, leading to a decrease in its carbon content. Consequently, this might cause the new coal not to burn as hot or last for an extended period as fresh charcoal would.

How long does charcoal burn?

A few factors determine the burning duration of charcoal, including its type and size, as well as the environmental conditions it is exposed to.

  • Charcoal briquettes are a popular type of charcoal for grilling, as they tend to offer an even burn that can last up to two hours or more, depending on the size and how well it is lit. Produced from compressed charcoal dust mixed with sawdust and other materials, these uniform-shaped pieces provide consistent heat without any flare-ups.
  • Lump charcoal is a type of fuel made from entire carbonizing pieces of wood. It’s known for being able to burn up hotter and longer than briquettes, with its duration reaching an impressive 2-3 hours!
  • Coconut charcoal is considered one of the most excellent forms of charcoal available. It can burn hotter, last longer, and generate less smoke than other types of charcoal, with an impressive burning time of 3 to 4 hours.

It is essential to be mindful that the duration of charcoal burning can fluctuate depending on numerous elements such as wind, temperature, and grill size. To ensure optimum efficiency from all of your charcoal during grilling sessions, use a chimney starter to light it – this will help prolong its burn time significantly!

How to store charcoal?

Preserving your charcoal is essential to guarantee that it will remain effective and usable for a substantial amount of time. As previously stated, moisture is the adversary of charcoal, so keeping it dry should be a top priority when storing. Here are some helpful storage tips:

  1. Keep the charcoal dry: The best way to make sure that your charcoal retains its effectiveness as a fuel source is by storing it in a sealed charcoal container, like one made of metal or plastic, with an air-tight lid. Doing this will keep moisture out and guarantee your charcoal remains ready for use whenever you need it!
  2. For optimum performance, integrate a moisture absorber, such as a silica gel packet, into your charcoal container in order to wick away any existing dampness.
  3. Preserve your charcoal’s quality and lifespan by keeping it in a cool, dry environment far from excess moisture or direct sunlight. Avoid storing charcoal in an area that is damp or humid, like the basement or garage, for optimal results.
  4. Elevate it: Keep your charcoal off the ground, either by storing it on a shelf or in an elevated container. Not only will this help to keep your charcoal dry, but it also prevents moisture from spoiling it!
