I have been buying Great value milk for years with no issues. Around October of 2018 I bought my 1st gallon of milk that had a weird taste to it. I smelled it, it smelled odd but not bad. It was well within date. I thought it was just a freak thing so I replaced it with another. The next day my daughter was asking me to smell the milk to see if it was bad. Had the exact same smell. She said it tastes bad in my cereal. I made powdered milk which we all usually hate and it tasted so much better. Off and on I have tried buying it again to see if it has improved. Now, January 2019 it is still awful and I will never buy it again. I told my husband "I think they are doing something to the milk", he laughed at me. I had him smell it and he thought it had gone bad. I told him the whole story and we have decided to never buy their milk again. It will be worth a trip to another store to not purchase tainted milk again. Maybe it's what they are feeding them. If so, they need to fix their diet. That stuff is nasty.
