I think there's a difference in the length of time storage is recommended
bewteen "freezer" (which I think means 0 - 32 degrees F) and "deep freeze"
(which is <0 degrees F.) I think that (unless you're running a milk bank or
something that would require long-term storage, a freezer temp. below 32
would suffice.
