I got about a cord of birch from a guy at my church in Jan 2020. He assured me it had been stacked in his shed for 9 years and was absolutely dry. I don't doubt it had been in his shed (as rounds) for nine years, he is a good guy, an elder at my church. But it wasn't dry. I actually split these rounds in Feb 2020 and had them stacked in March 2020. Most of it is burning pretty well, but not all of them.
I readily agree that some rounds from species other than birch can/could dry as rounds stacked in a shed, and I readily agree birch is the "extreme", as in no one makes canoes out of maple bark or ash bark, but this is exactly why I don't believe unsplit rounds are "seasoned" no matter how long they have been "seasoning."
FWIW this is a cordwood fired BBQ at work, not my wood stove.
