One of the beauties of vacuum packing is that you can freeze it with little harm. How long it will keep unfrozen depends on how dry and how salty you smoked it.

I notice that there are commercially packaged products on store shelves that are not refrigerated. I don't know if thay do anything special to extend its shelf life or not.

I smoke mine with very little salt and keep it quite moist. Even so, it is good in the fridge, if vacuum packed, for at least a month or so.
