HERSHEY'S Shelf Stable Milk can withstand temperature variations wonderfully.
Putting the product on the shelf then in the refrigerator back and forth causes no harm to the product as long as it remains unopened.
The best temperature to store the milk is from 33° F to 80° F.
It can withstand higher temperatures but this will cause the milk to age quicker (leading to off flavor and a slight brown tinge).
The temperature the milk can be stored at is related to time. Storing the milk at 81° F to 108° F over the shelf life will simply cause the milk to age sooner but will not cause injury or illness. Storing the milk at 109° F for more than 10 days may cause the milk to sour or carton to swell but will not cause injury or illness. Storing the milk at 131° F for 5 days or more may cause the milk to sour or the carton to swell but will not cause injury or illness.
The milk should not be frozen as this will cause the appearance of the milk to be off.
We recommend serving the milk chilled.
After opening refrigerate the product and use within 14 days.
