I don't vacuum seal it, just put it in plastic food bags, generally one or two gallon size, and twist tie them, then store them in a cooler of ice till I get to processing it, generally within two or three days. I don't wait 10-14 days, not saying it isn't right or even that my way is better. I am so used to my way, and I like it as it is, that I just simply don't want to change.
We need to be a little careful with making the "piles" too large because cooling like that is by conduction (slow) and the lag time could promote bacterial growth. This is repeatedly shown in lab tests.
Get it cold quick as you can, keep it cold till you freeze it.
