I just had this happen to me on the last order i just got an last week i was pretty mad because that is my everyday snuff and i live in nevada and its only once every three months that i place big order. First i thought wow thats some strong amonia took pinch and still menthol heavy i had just run out of my first tin and was dying to have it again fresh as roses. I let air for just a little bit 15-20 mins but in my area its a humidity of 20-30% so i dare not dry it out anymore i already have to rehydrate a full tin after a month of my normal use, which is not too much throughout the day since i am new to snuff. Wrote to Mr. Snuff and they got right back to me credited my accout forna new can of viking thors hammer,thank god i also had 100g supplie as well but i didnt want to crack that open just yet but i had too. Now my old is a third way full of minty thors hammer with viking blond and viking black i attempted to make it something not mentol but its still not what i want next order will have more vikings in bulk supplies as well as more to add to my new devopoling collection. But i have to find new tins for thors hammer that isn’t contaminated with menthol. Using a plastic tupper ware tub to store a weeks a time worth of snuff at a time storing the bulk in refridgeator at this time i hope my bad humidity dosnt screw me up, got the first tin rehydrated but the flavor was half i of what it was. Now i have strong menthol snuff along with the other 30 or so snuffs in my in collection.
