+1, and there are different types of burleys out there, ranging from some pretty weak white burley to some pretty strong stuff. I tend to put Kentucky Fire Cure in the burley category too, but that is for my own mental separation, as well as Rustica. The way growers, processors, tobacconists, and consumers separate the different leaf types is very different depending on what level you are at, with the consumer being the least informed. But, none of these levels seem to correspond with the way the others do. There is even different jargon for the processes at each level.
Among the burleys the variety seems to be what gives each its differences in taste. There are literally hundreds of different varieties available.
Jitter, isn't some burley sun-cured as well?
