Burros
In the context of the 2 Stage Fermentation model that TU teaches, Burros are the 4 to 6 foot tall piles of tobacco which constitute the most intense Fermentation period. Unraveling and re-piling occurs at critical temperature points so the tobacco will not "burn out".   In other countries, the term Burro can refer to any Fermentation pile.
