Making Latakia. Man, that would be a project and a half. The fires used for fumigating Syrian and Cyprian tobaccos were fueled with different woods. The stone pine was reputed to be the dominant fuel wood for the Syrian product. I get more of a sweet, hardwood smoke taste from Cypriot stuff, though sometimes, there's an undercurrent of pitch that finds its way in, so a pine might be part of the mix. Could it be done domestically in any quantity? That's a tough one.
Dark fired KY leaf undergoes two or three firings, a process that takes several weeks, and it has nowhere near the 'campfire' character of the latakias. I have no idea how long the process takes in Cyprus, or how long it took in Syria when they were still doing it. (No Syrian has been produced for well over a dozen years. What's in warehouses is all there is, and very likely all there will ever be.) I imagine getting permits to fumigate tobacco to that extent on a more 'industrial' scale might be challenging, to say the least. And, that assumes the right leaf could be acquired, at the right stage of cure.
It's an interesting thought, though. And, sure, it could be done on a small scale.
As for differences in the latakias we see in different blends, um, yeah. There are different grades, but additionally, some manufacturers 'do stuff' to it, whether it's casing it, or adding humectants to make it more pliable (latakia is notoriously frangible, and hard to handle in its dry state without it turning to dust), or steaming it, or anointing it with holy water drained from the cisterns of the My Lady of Sobranie cathedral...
Me? I prefer to let it do what it does naturally. I'm funny that way.
