As recommended get yourself a vacum packer, it will easily keep your venison good for a year or longer. My wife purchased one for me last year and I packed away my venison using it and it worked great, especially compared to trying to bag or wrapping the meat with freezer wraps, etc.

The meat that's left still looks great when pulled out of the vacum packs after 11 months in the freezer. I'm quite impressed with the results.
