Bitter taste - milk expires before date

I’ve been buying Lucerne 2% milk from my local Albertsons store for awhile. But the past few times I’ve bought this brand milk, it has expired before the expiration date with a sour taste. I’ve had to throw out half the jug. Today with half the gallon left, it had a bitter taste to it. I had to throw it out again. I feel like I’m wasting money on this poor quality of milk.

Chemical Taste

The milk had a bad chemical tastes only two days after the expiration date. It was not the usual/normal taste when milk starts to go bad. I will never buy this milk again. I do not understand why it would have a chemical taste at all.

Just bought one that had black substance in the bottom.

Will never buy again. Always turns before exp. date but this last batch had a black substance in the bottom that looks like mold and we got sick. Our neighborhood board is reporting others had this issue as well, all bought from the same store around the same time.
