Stem (Vena)

/ VEH-na /
Production & CuringSpanish
Definition
The central midrib of the tobacco leaf, along with the larger veins branching from it. Stem material is woody, low in flavor compounds, and burns unevenly, so it is removed from premium cigar leaf and often sold off for reconstituted sheet or fertilizer.
Why it matters
A stem left in a filler leaf is a common cause of a hard draw or a burn that runs to one side.
In context
"He blamed the plugged draw on a piece of stem that got past the bunchers."
