LM365 Blue White Portion Snus has a taste of Småland berries with an undertone of licorice, which gives the snus a certain sweetness. In addition it has a classic tobacco flavor and nicotine content of 13 mg/g.
I have heard about rustica - that stuff sounds strong. I would only use an air-cured tobacco in a nasal snuff if I can. I don’t use nasal snuff much...
