Can you freeze milk to make it last longer?

I like your idea. Not the adding vinegar part to make cheese, that probably won't turn out quite right. But I will boil it to kill the germs. Isn't that what people did with spoiled milk and food like 100 years ago before there were refrigerators? My grandmother used to tell me when she was a kid in the early 1920s, her mom would brush maggots off the meat and boil it real good and still eat it. It still wouldn't taste or smell good but the boiling would have killed the bad germs. She told me spoiled meat would only make you deathly ill if it wasn't boiled and cooked all the way through
