I saw the "UHT Processed" label at the bottom left corner of your image and was curious. A quick search revealed that UHT stands for Ultra High Temp. and that this milk (if unopened) has a shelf life of 6 to 9 months with no refrigeration. Also, the heating process can change the smell and taste of the milk. Very Interesting!
