Ultra-Pasteurized (UHT) milk takes the longest to expire, often lasting several months without refrigeration before opening. This is due to the high-temperature process it undergoes, which eliminates most bacteria, prolonging its shelf life. Once opened, it should be stored in the refrigerator and consumed within 7-10 days. Ensure proper storage to maximize freshness and longevity.
