Thank you for sharing the conversation with the Sutliff production manager — interesting perspective. However, the phenomenon of white crystalline bloom on aged pressed tobacco is not "absolutely unique" to Sutliff products or their specific black paper. It has been reported and discussed for decades across many brands (G.L. Pease, McClelland, Esoterica, Cornell & Diehl, and even some European flakes) — long before Sutliff popularized it on their packaging. Greg Pease himself (one of the most respected blenders) has written extensively about it, calling it harmless mineral salts and natural oils migrating to the surface during fermentation and aging. No health concerns, just a cosmetic byproduct of good leaf. I'd be genuinely curious to see the actual chemical analysis Sutliff conducted on these crystals — composition, safety data, etc. If it's truly unique to their process, they should have no problem sharing the lab results. Until then, decades of collective experience from smokers and blenders suggest it's safe and not mold.
