One of my semi-local cheese processors (Gosner's in Logan, UT) makes shelf stable milk, and I have been using it for quite awhile. It is regular milk that is ultra high temperature (uht) processed to make it shelf stable in a package. No refrigeration required...until you open it.
Now it is becoming more and more available in the mainstream stores. Costco carries the chocolate milk version, but I just found some of the regular 1% in Walmart. The brand name was TruMoo, and it was hiding out with the kids' lunchbox drinks.
It is awesome for camping when you don't have ice or refrigeration available. It is also nice to just have some in the camper cupboard for those times that you don't get out of the woods long enough to get to a store. The great thing about it is that it doesn't taste like "canned" milk. It tastes like regular milk. I really like that it is available in 8oz servings so that I don't have any leftovers after breakfast etc.
