There’s an unfortunate dearth of truly unflavored straight burley on the market.
There’s c&d dark burley. There's c&d white burley. The company sells a couple of blends of the two.
There's the semois, mentioned above.
Or one can go the whole leaf route.
Those, truly, are the only options I know about. I'm reading this thread with interest to see if I learn of others.
Well, people sometimes mention cotton boll twist. I have not yet had the privilege of trying it.
I guess you could say two timer is unflavored, but it's been toasted--twice--thus the name, making it a much milder experience.
I definitely detect a topping on 5 Brothers (it's cocoa or something that brings out the natural cocoa flavor of the burley). I actually don't think the topping is that light either. It just seems light due to the strength of the tobacco. The beauty of five bro's is that unlike so many other codger blends it hasn't had the life toasted out of it. I actually put 5 Bro's in the same category as Crooner: they are those rare straight burleys that have been pleasantly topped without being castrated. This is another underrepresented category in my book. I'd love to know of more.
I think the lack of truly straight uncased untopped burleys is a great shame. I would love to see more offerings of cuts--shags, ropes, plugs. And I suspect burley must have tremendous potential to change in interesting ways with terroir.
