Flue cured tobacco shares some similarity to fire cured tobacco in that it is heat that is the driving force in the process. The difference between the two is that where fire cured tobacco has the leaves being open to the smoke produced from the fire, flue cured tobacco has the smoke diverted through an intricate ventilation system allowing the tobacco to remain unflavoured by the smoke. A tricky technique to master requiring a lot of space, it is one of the less common methods used. The tobacco ends up a vivid yellow or orange and has a natural sweetness in comparison to tobacco that has been fire cured.
