Mine has a date on it, it usually starts to taste funny right on or the day before that date. I've read milk can be frozen but I've never done it.I had Mocha Mint cappuccino made with warm regular milk this morning. My mom bought so much milk that I'm afraid it will spoil. How long can you keep milk in the fridge before it goes bad? She is starting to hoard milk now, she never did that before.
