The Science Behind Firewood: What Makes the Best Burn? Dec 11, 2025

When it comes to preparing for cool evenings by the fireplace or lively outdoor gatherings around the fire pit, choosing the right firewood is key. At Leland Firewood, we understand that not all firewood burns equally, and exploring the science behind firewood can help you select the best options for your needs. So, what exactly makes the best burn when it comes to firewood? Let’s dive into the essential qualities that define top-notch firewood.

First and foremost, moisture content plays a pivotal role in how well wood burns. Freshly cut or "green" wood contains a high percentage of water, potentially up to 50%, which leads to poor combustion. As you might imagine, trying to burn wood that is loaded with moisture results in a lot of smoke and little heat. That's why "seasoned" firewood is the ideal choice. Seasoned firewood has been dried, reducing its moisture content to 20% or less. This process, typically accomplished by air drying for six months to a year, ensures that the wood burns efficiently, producing more heat and fewer emissions.

Species of wood can also have a significant impact on the quality of the burn. Hardwoods, such as oak, maple, and hickory, are favored for their dense composition, resulting in a slower and hotter burn. These woods are excellent for long-lasting fires and are particularly valuable for heating purposes. On the other hand, softwoods like pine or cedar ignite quickly, which can be useful for kindling or starting a fire, but they tend to burn out faster and produce more soot due to resin content.

Beyond moisture and density, the concept of BTUs, or British Thermal Units, measures the energy output of firewood. Hardwoods generally offer higher BTUs compared to softwoods, translating to more heat generation per log. High BTU logs are efficient, requiring less wood to generate substantial warmth, making them an economical choice for those looking to heat their homes.

While understanding these factors is essential, proper storage and preparation of firewood can optimize your burning experience. Store your firewood in a dry, well-ventilated area off the ground, ideally covered but not sealed, to prevent moisture accumulation and ensure that your logs remain seasoned. Additionally, splitting wood before storing aids in the drying process, exposing more surface area to the air.

It’s not only about heat and efficiency; sustainability is another critical aspect to consider. At Leland Firewood, we prioritize sourcing wood from sustainably managed forests, helping to reduce environmental impact. Opting for locally sourced firewood also means you're supporting local industries and reducing carbon emissions linked to transportation.

In conclusion, the best firewood is defined by its moisture content, wood species, and BTU rating. By selecting well-seasoned hardwoods, storing them correctly, and considering the environmental impact, you ensure that your fires will be both warm and eco-friendly. At Leland Firewood, we are committed to providing premium, environmentally responsible options to enhance your fireside moments. Whether you're heating your home or enjoying a fireside gathering, our knowledge and quality firewood will keep the flames burning bright.
