I've tried Burley dominant blends (not heavily cased or topped ones) with minimal results. Never bother with English because I don't smoke latakia enough.
I also base my opinion on the sugar content of the leaf. The sugar content is what gives these desired effects. This makes sense why Virginias would be best suited and things like Burley and Latakia may be more subtle or less impacted by the process.
Though I'm glad to hear you've enjoyed all your experiences. I've read many that were unsatisfied with the results and a jar of ruined tobacco.
So a leaf would have to have zero sugar content to not benefit from this process? I don’t look into it that much - do Burley and Latakia have zero sugar content?
Maybe my palate is just shot, but the idea that this process has ruined tobacco is kinda out there if you ask me. To each his own, but it’s had a similar effect (improvement) on the numerous blends that I’ve done. Perhaps what you’re reading is more VA bias? The sugar content makes sense, but to posit that non-VA blends are ruined by the process would be a tall claim from what I’ve experienced. Sorry it worked out that way for others.
Suffice to say I’m happy that every blend I’ve ever done has turned out better. I’d be upset if my results mirrored the stories you’ve read.
