How long can unopened milk sit out? The FDA asserts that you should never keep unopened milk out of the refrigerator at room temperature for more than two hours. However, this window reduces as the temperature rises. This means that when the temperature exceeds 45°F, unopened milk can last up to an hour.

The process that gives the milk a longer shelf life is called ultrahigh temperature (UHT) processing or treatment, in which milk is heated to 280 degrees Fahrenheit (138 degrees Celsius) for two to four seconds, killing any bacteria in it. Compare that to pasteurization, the standard preservation process.
Raw milk goes through varying stages as it sours. It starts off by slowly decreasing in sweetness each day it sits in the fridge, and if you leave it long enough, it will eventually separate into curds and whey. Soured raw milk will maintain a “pleasantly” sour taste and smell.
