A good question regarding the snuff makers handling of the obviously fire cured tobacco for American Scotch Snuff. It is possible that intentional “toasting” is done to it but I think its color would be much lighter if that were true. Also the effort to “toast” would be worthy of mention in one way or another due to the expense as well as its selling point (fame) and there is no evidence of any mention. It may be that some heat involved with bringing into proper case is there but not to the extremes of “toasting”. As a tobacco by-product in America I’m sure little expense was given to Scotches. Some salts added, some sugars to the sweets, they probably don’t even use sieves having machinery that pulverize everything going through.
