Not sure if it’s weather related (below freezing temps around here) or perhaps technique related but I’ve been finding the last portion of unburned tobacco to have become a crusty puck. More than what I’d consider dottle, but not much more. Definitely not wet dottle as one might expect. I can tap the puck out once I start struggling to keep it lit near the end and it comes out as a crusty puck. Perhaps it’s all spent tobacco but wondering if I might be doing something wrong.
