I hate to be the bearer of bad news but most of the milk you buy in liquid form is from powder, the largest milk processors on the planet are quietly turning it into powder, in large kilns,mastering the outcome, going unnoticed while taking a perishable product, extending shelf life gaining a better handle on supplying the market, making it easier to transport as well. Dairy products are not very good for you, nor are dairy farms good for the planet, your water supply, the fish and the oceans, It is a very dirty business, cows are now kept constantly pregnant and in barns all their lives, It is major cause of obesity, heart decease, cancers and bone deceases, contrary to popular belief, it is not a healthy product and if you love your children you should get informed, a good place to start is the documentary The Truth about Milk. They now sell powdered soya milk.
