I grew up on UHT milk, it's the kind that is super heated then chilled quickly, then heated again I believe, and then sits on the shelf unrefrigerated and won't go bad for months. I could never drink it warm, and it was only cold enough with ice cubes, and every summer when we came to Utah, we'd get so excited to drink normal milk. Looking back, that stuff was disgusting.
BTW We drink 1% milk in my home, it's a compromise between whole, which is gross, and skim, which is also gross.
