A roll of loose is 450 grams as a can has 45 grams. That's compared to 24 grams for portions. So... 900 grams is equal to 2 rolls of loose snus. So yes it does contain more snus then the portions SnusX just as a standard can of loose has more snus then a can of portions.
I think the light bulb clicked on. You'd be getting almost twice as much snus in los? What has me confused is the statement that the los was not dehydrated as the portions are and that 50% was water weight.
