in store and in home thermometers important

Wiping off of the mouth of the jug can help.
Also, keep an eye on the cooler thermometers in the store. They are supposed to keep track of the temperature and keep it steady, but we have noticed in the past that often they don't. The temperature should be between 0-4 degrees Celsius. Some stores are better than others at keeping temperatures correct. Not all coolers are created equal either as some are more open to the warmer air.
To add to that, no matter how cold your fridge (or beer) feels like at home, or no matter what number your fridge is set at (that will not show the correct temperature ever, it is only a general setting), it should be between 0-4 DEGREES too, not the SETTING of 0-4. The closer to 0 degrees the better for keeping milk lasting longer.
To keep track of fridge temperature, get a fridge thermometer at Walmart or elsewhere. It can make a difference.
These things are in your control, so I would say to start with that.
Anyone who has kept milk cows will tell you that everything the cow eats affects the flavor (weeds, corn, soy...all not pleasant...fresh grass, alfalfa, good hay...tasty and sweet).
At any place along the handling/processing/shipping something can happen to the milk as well. There is a lot of equipment to keep clean, refrigerated trucks and so on to keep up and working right. Anything can happen at any point in that process and affect the flavor. The least handling the better when it comes to something perishable.
The plastic it is stored in also affects the flavor. I can taste plastic in a lot of packaged foods (not just processed milk) and it is never a nice addition. I have wondered if different companies use slightly different components anyway in their jugs. As well, does anyone know if the cartons are actually wax lined as they used to be, or now plastic lined?
Keep in mind that none of the milk is truly fresh either as it is shipped here and there and it is truly a long time before it even gets to the store. You will not get milk within a few minutes or the day from the time it came from the cow.
There are a lot of dead things left in the milk too after processing which doesn't turn the milk sour...it actually goes rancid as they rot. There is a definite difference between raw and processed when it starts to turn and of course, this rancidity can start to happen anywhere along the process depending on its environment.
Anyway, just a few things to think on. I like sweet milk, so it has always been a big thing to me. I do not like it sour nor rancid and will not drink anything if it is off even a little.
