I have smoked, dipped, and snuffed my way to an idea. I wonder if the difference in how American Scotches and plain English snuffs react with my nose may have something to do with the fact that American scotch snuffs tend to be fire cured. I'm not sure of the English ones (whether they tend to be fire cured or not), but I do know that snuffs that have a woody or smokey smell tend to make my nose run a little. I wonder if the fire curing causes a chemical change that affects this. WoS has never made my nose run, and the ones I have used tend to be redder in color. Any ideas?
