answer:I found that after I started buying organic milk, it would keep for a long period of time and still be fresh. I’m talking weeks, and it’s still good. I buy the Horizon brand, 2%, the one with the smiling cow on the box. I could probably drink skim, but 2% is a habit. The other thing is that the milk seems to taste richer. The Horizon whole milk is more like half and half in the store brand, the 2% tastes like whole milk. I think it’s probably because it’s in a paper carton, and not exposed to light, like in a plastic container. If you had problems with one particular store, the problem is most likely that they are not storing their milk at a proper temperature. I would say the fault for bad milk lies either with the type of packaging, or the storage temperature – in your refrigerator, at the store, or at the milk processor. Probably not the producer or the cow.
