@PhilipS ans Johnny: In the oldest books I read dating back to the end of the 17th begin 18th century there no mention of fermentation. Tobacco is flavoured with flowers, in putting the flowers directly between the tobacco leaves which are lateron ground and sieved. Tobacco leaves are also flavoured with watery extracts of flowers and carefully dried, ground and sieved afterwards. Bisam and musk are ground with sugar and mixed with ground tobacco.
Salmiak is indeed amoniumchlorid and Potash is potassiumcarbonate.
I think the fermentation of snuff tobacco started in the 18th century in order to prevent detoriation. In a Dutch dictionary of 1802 the Karot as a bundle of tobacco leaves is already mentioned.
At the moment we are chopping the St. Omer karotten what will take some more time because the tobacco is still very humid and as there is no heating in the mill there is hardly any evaporation at the moment, but we still working on it. In the meantime we are going to produce some more “historical” snuffs.
