I am originaly from Germany. It is normal in Germany to buy so called 'H-Melk'.
1) No need to put in the fridge
2) Store for multiple week's
3) For Store's: No need to put it into a cool room
4) For producer: No need for a very quick delivery and cool transport
When I am in Germany I bring every time this Milk with me. In my Hytte I do not have a fridge - I have every time good quality milk.
