Lee when I was cooking on the commercial fishing boats that I worked on, we would have to buy provisions for weeks on end. We froze our milk, but I would open the full container and pour a little out first as it expands a little. Milk freezes well. But when defrosted the shelf-life is short in my opinion
Lee there's no problem freezing milk. The only issue is when defrosted the shelf life is shortened a bit. And depending on the size of the container it takes a while to defrost. we bought gallon size containers. Like I said my other post it does expand a bit. So leave a little room in the container. Good luck
