Of course, they have begun to separate. I hate opening up the sour cream and there is an inch of liquid on top of the cream....GROSS!!! Not saying this is the point that I throw it out, but it is just gross. I do know plenty of people that will throw out products at this point though.
Well, the trick to making sour cream, cottage cheese and yogurt last longer is to store them upside down in your frig. This way the liquid will no longer be right there on top of all the cream. ***Just make sure the lid is secure or you will have a mess in your frig. Problem solved!!!
