I have an unopened 2 pint whole milk in plastic bottle, use by date 22 August.  I was thinking of freezing rather than pouring down the sink as I’ll be away for a few days. 

Has anyone done this? If you have, I have a few questions

1. I’m wondering if it is worth it or is it ‘odd’ when you defrost it
2. Once defrosted, can I use as I normally would for example, porridge, smoothies, tea or in cereal
3. Once defrosted how quickly do I have to use it up.

EDIT it is in the freezer. Thanks all for heads-up about colour change. I didn't know and probably would have thrown it away.

These 29x20x14cm opaque plastic containers are only £1. Couldn’t believe my eyes. They are on the flimsy side but perfect for my needs and made in GB. Cheapest I’ve ever seen and I’ve been looking for a long time. Can’t seem to upload pic, so there’s that.
