For last season and this current season my wood piles have consisted of (basically in this order): pine, willow, fir, birch, apple. Pine and willow make up close to 75% of the wood though I'd say. Obviously this is less than ideal, but it was all free stuff I had access to - just my time to cut, split, haul. Also due to lack of space and time, these woods were great because they season in 6 months to a year quite well. Pine is also the best (in my opinion) fire started when dried properly. Now, I'm trying to get some wood with more btus in my stack for next season and again, due to lack of space and time, am interested in which woods season the quickest. These are the hardwoods available (didn't list Oak because I know it takes 1/2 an eternity to season). American Beech Black Cherry Grey Birch Paper Birch Yellow Birch Red Maple Sugar Maple White Ash Which of these woods would you folks rank as quickest to season?
