Hot Spot

ConstructionEnglish
Definition
A point that burns faster than the tobacco around it, producing a run or a canoe up one side. It usually reflects uneven filler density or a thin patch in binder or wrapper.
Why it matters
Hot spots raise combustion temperature locally and turn the smoke harsh; catching one early with a touch-up is far easier than correcting it after it has run.
In context
"It ran up the seam - hot spot, probably a gap in the bunch."
