Cap

AnatomyEnglish
Definition
Piece of wrapper leaf applied over the head to seal the end where the wrapper spiral terminates. Caps are cut from wrapper offcuts and fixed with a trace of vegetable gum; on a well-made cigar the join is nearly invisible.
Why it matters
Cutting past the cap's shoulder is the usual cause of a cigar unraveling, so knowing where the cap ends tells you where to cut.
In context
"Cut just above the shoulder and you leave enough cap to hold the wrapper down."
