Reply to comment by DroolingSlothCarpet in LPT: Add a piece of silver to your milk jug. The antibacterial properties will make the milk last a couple weeks past its expiration date. by bratman33

“A couple of weeks” is based on personal experience, trying to see when the I could discern a difference in the taste of the milk. Although I would say ~10 days is more accurate to my experience. Also, it doesn’t expire by growing bacteria, rather it seems to start separating. I have no idea what the reason for that is.
