Why does sun curing taste so different from air curing in my burley. I harvested all the same leaf position and sun cured about 100 leaves and air cured the rest. The sun cured tastes harsh and burns the nose badly where as the air cured tastes much better and smoother. All of the burley was fermented for 36 days at 124%. Also why did the air cured tobacco turn very dark after kilning where as the sun cured stayed a much lighter color. Also the smell is much better and very different in the air cured. Why so much difference in smell? This is all the same leaf so I am interested in what is causing all of these differences and how to manipulate these differences in the future.
