This is going to sound so silly but what is the difference between the fresh bottled milk that you buy from the supermarket which is stored in the fridge and the milk that you get in cartons not stored in the fridge?...i just don't get it?

Fresh milk is not pasteurized, which means it spoils more quickly and has more bacteria in it -- some people are just fine drinking farm fresh milk because they're used to it, but for someone to go from carton milk to farm fresh milk you should probably expect an upset tummy at first..
How weird that they keep milk out of the fridge lol. In Canada our milk is all pasteurized and kept in the fridge, even at the grocery store.. and it is actually illegal I think to sell unpasteurized "fresh milk"... a farmer just went to court bc he had been selling it to the public (beat the charges though).
all that aside fresh milk is drinkable and carton uht milk tastes proper cack
