Okay, so I’ve read a bit about folks grinding their own from air-dried twists and such, and seen references to the finished product as being nice and strong. Here’s a question, though - how’s the burn on those? The odor? Drippy, are they? Does anyone have any experience with the plug chewing tobacco? I’ve dried some, at great effort, and made an insanely strong pipe tobacco, using Day’s Work Plug, but the experience wasn’t worth the trouble. So, for one whose snuff-intake is limited to the Garrett scotch and rappee and similar American Scotch snuffs, plus a little homemade from Carter Hall pipe tobacco, how do these grind-your-owns made from twist stack up? Along the same lines, I’m curious to learn about what would make a satisfactory substitute for the old snuff-rasps? Maybe one of those micro-plane nutmeg graters? I’ve become intrigued with rappee for no particular reason, and suspect that twist or maybe even bone-dry plug might make a good base material.
The American twists are quite strong, they smoke strong too. If you are not used to strong tobacco, one good pinch can give you a sweaty brow. The twists I have tried are Cotton Boll and Stokers air cured. I think they are pretty close in strength. The flavor and scent is pure tobacco. Rather pungent, earthy, vegetal. I’m not sure, but I’m thinking these are of burley. It might be good to mix in some virginia or cigar leaf, or try some of the SG or GH twists. I do get a fair amount of effluent from taking these. Sometimes a bit of throat burn, but not too bad. As for a snuff rasp, I would think a ginger rasp would work well. 
Twist is the only way to go. Flat plugs are around 60% additives and moisture. Too difficult to powder & the results are nasty. I’ve thought about one of the rasps that sprang pictured, but never tried it. Most twists are made of dark air cured or fire cured tobacco. For the rest, sprangalang has already said it.
@snuffgrinder Yeah, I think the disaster that was my plug tobacco experiment proved that. So, twist it is, then, and that ginger rasp, or one of the nutmeg ones, might just do the trick, as I’ve read that a lot of the old-timers used either one, and that even collectors of the snuff-rasps report that many examples are mis-identified as nutmeg or cinnamon graters. I’ve always loved the smell of pure tobacco, and think that maybe a twist might be a good source material for experimentation along these lines.
Sprangalang, what about the Five Brothers?? And what about Black Twist, was that your making Snuffgrinder? Both very, VERY nice indeed.
Pieter, I still have not tried snuffing the those. I think Matt did, I think he said the 5 Bros is very good. I did try some SG Brown # 4 once, I remember it was pretty nice. I’ll have to try that one again.
Not mine, Pieter. I sent you the high toast and bubble gum scented. I haven’t tried 5 Bros, but I used to get a very similar brand called Plow Boy. It made a really good snuff. Unfortunately, it’s long gone.
