My sausage is made by the local butcher. I just bring him the deer and tell him what I want.
Recently the butcher started vacuum sealing the sausage. But I can not tell the difference between the vacuum sealed and the wrapped in paper sausage. The butcher wraps or seals the sausage after its smoked. 2 deer usually give my family enough sausage to last a full year. A year after the deer has been processed, and its still good either way its packaged.
The vacuum sealed might be a little better. A year after the deer was packaged in paper, I have seen frost develop around the sausage. But around here, we cook deer sausage almost every time we grill. So by the start of the next hunting season, we are almost out and time for a refill. If I had to pick between the two, go with vacuum sealed. This also saves room in the freezer.
One of the two, 8 points I took during the 2006 - 2007 hunting season.
