I think it's the natural smell of the oak you are burning. Various Woods have various Aromas
Alright peeps, when I burn wood I get this stange acrid smell. Not a nice smokey smell, but a sharp unpleasant acrid smell. Any one know what it could be? I burn well seasoned oak. Pipe is clean, just had it done before the burn season. And if you've experienced it before, can you give me some tips? I would like my neighbors to stay friendly.
