Vacuum sealed deer meat will last around 3 to 4 days in the refrigerator but if you freeze the vacuum sealed deer meat it will last from 6 months to a year.
For the best taste and freshness you should eat the frozen vacuum sealed deer meat within 6 months but it's still safe for a year or two in the freezer.
Frozen meats last longer than meat that is just refrigerated.
The deer meat will likely still be good even for 3 years frozen but might get freezer burn and may not taste as good.
Eat it within 2 years though for the best taste of the deer meat.
