square tub versions. I've also reviewed the round can versions of Siberia Red, Siberia Blue, and Siberia Brown. I recently reviewed the Siberia Blue (Slim White) Portion and the new Siberia Red that was released on the Canadian market. With all these products now available, it still seems that Siberia Red holds the crown for fan favorite. When it comes to the flavor description, it is described as being "the slim portion version of Siberia -80°C White Dry Snus. Like the original, it's packed with 4.3% nicotine for an eye-opening experience but is now in a slim portion pouch for smoother mouth feel." This product has a nicotine content of 4.3% or 43mg/g. The can weighs 13 grams and contains 21 portions, which equals out to about 0.61 gram portions. The nicotine content per portion is 26.61mg/portion.
