I have only had the black rope, and since that was too strong for me on its own I decided to leave the brown ropes alone! might revisit now though...
But you smoked cotton ball twist which is brown and stronger than almost anything, and you almost puked on my deck. The brown bogie isn't as strong as cotton ball.
To answer the question of does it contain cigar leaf? Well according to the websites that sell it they don't, according to tobaccoreviews which is really unreliable brown #4 does. I would say that it doesn't even though I haven't tried it. What I think it is, is the wrapper, which does have a cigar like taste. Which brings the question what exactly is cigar leaf? Why it's simply a type of tobacco and there are several different kinds of cigar leaf, which is simply different kinds of tobacco. Brown bogie has that cigarish kind of taste a bit but that is the dark fired wrapper. Unless you're looking for an extremely strong smoke, at first I found this stuff to be too strong for my liking, but after a while I've grown very fond of it. It's just pure unadulterated tobacco taste. It definitely has cigar like notes to it, but this is a strong smoke not for the beginner.
