excess condensed milk - storage

[BlueChampagne]

I've got some condensed milk in for a particular recipe, but the tin is larger than I need. Does anyone know if/how long it can be kept (in fridge/freezer)? I'd like to use it all, but with the best will in the world, I can't get it all done in one go!

I've frozen it before. It doesn't set in the freezer though so bear that in mind when choosing a container :)

Great - thank you!
