Pine and spruce are the best kindling you can find for starting a fire out in the firepit or woodstove. Though it shouldn’t be used as the primary charge in a fire due to resin that can cause creosote build-up, it will catch quickly and burn hot to get a fire going.
Pro tip: Many make the mistake of starting a small kindling fire and then adding larger sticks and logs on top of it. Since half of the energy stored in wood is released in the form of gases, this process would be very inefficient. A fire at the bottom would heat the wood above it, which would release gases that would not be consumed by the flame below and the gases would be lost or only partially consumed. Rather, you should start by loading up a woodstove or pit by stacking split logs and creating a small kindling fire on top. The kindling fire will make sure the gases from the logs underneath are consumed before the logs catch completely and the fire will work its way down through the log base resulting in an efficient burn.
