<p>We’re leaving town and I have an unopened gallon of milk. Can I freeze it as is, in the plastic jug?</p>
<p>I would open it and put some Saran wrap over the top, so that it has room to expand.</p>
<p>I’m assuming so as I used to freeze breast milk without difficulty. I would worry more about the integrity of the container. I can’t tell you the times, someone around here has dropped a gallon of milk with the thinner walled obviously recycled plastic and broken it with just the slightest bump. Maybe would want to transfer it to a different container.</p>
<p>Yes. You can freeze milk. Pour out enough so that the mild had room to expand and then reseal --I would use the cap AND NOT SARAN WRAP. If you leave a little room for expansion it will be fine and not burst. I would pour out (or drink!)two cups out of the full gallon.</p>
<p>Yes, you can. I do it all the time. I’d follow sunnyflorida’s advice, except that pouring out about a cup is plenty in my experience.</p>
<p>In my experience, milk that is frozen and defrosted turns sour faster than it normally does. But I still freeze it from time to time, if we’ve overbought for some reason.</p>
<p>Our farmer relatives in Iowa used to freeze milk all the time - they lost power or got snowed in frequently in winter, so they always kept some milk in the freezer.</p>
<p>Growing up our milk was delivered in our town. And it always froze sitting outside in the winter!</p>
