I would think it would help to use Styrofoam as insulation. Similar to
wrapping pipes in winter. certainly better than non insulated storage.
sugar in water should still freeze like a Popsicle ultimately, though the
foil juice packs may have room for expansion, try it in the freezer,  I
still think the easy way is just allow room for expansion as you said and
use jugs.

Just pack Tequila .....lol
