I have been making my own snus for a couple of years and thought i should share some pictures (found here
) of the process. It is really easy to make snus and even though it might not be Swedish Match quality i am not ashamed to let friends, family and coworkers have a taste.
I suppose an explanation might be in order;
The water is, obviously, a humectant and the salt (NaCl) is added primarily for flavouring, but also as a preservative. The sodium carbonate (Na2Co3) is used to regulate the pH. If you want a milder snus, use less, and if you want a stronger snus, use more, but don't overdo it. The propylene glycol (C3H8(OH)2) is a humectant and also helps to bind the snus together. The sodium benzoate (NaC7H5O2) is a preservative which is added since this snus if fermented and not pasteurised. During the fermentation the reaction of the sodium carbonate occurs and the tobacco is matured, you can tell when the process is done by looking at the colour. The snus should be very dark, almost black, and not just light brown. If you are in a hurry you can speed up the process by increasing the temperature but this will change the taste (one of my coworkers actually prefers his snus this way so there is no harm in testing it).
I suppose that's the gist of it. Feel free to ask if you are curious about anything, while i am no expert in the chemistry of tobacco i have learnt a thing or two over the years as a DIY snuser.
