Recently made a Schmalzler - a very simple one, using the darkest cigar I could find, and butterschmalz.
Here are some insights I didn't mention in the video:
1. A zester is a cheap, reliable, and easily obtainable tool for grating tobacco into a snuffable size. I always used to use a coffee grinder or a blender, and I found that there was no real way to stop the tobacco from blasting right into a super fine toast grain (especially with the coffee grinder). The zester is my new recommendation for anyone looking for a way to make tobacco flour of a good size for snuff!
2. Different fats, especially butterschmaltz or duck fat, were probably added to snuff because they smell really, really good.
3. Schmalzler bottles were probably used not only because they keep the air interchange within the schmalzler to an absolute minimum, but also because you can dump a fluffy pile onto the back of the hand, the fingers, or the knuckle without compressing the snuff as you do with an English style. It doesn't matter so much with water-moistened or dry snuffs, but with schmalzler, the fluffier the pris is, the comfier it goes in.
