I bought a bottle of skim on Saturday & opened it today (Monday) to find the bottle plugged by something solid white. It didn’t smell, so I used a spoon to scoop it out. It was gooey. Milk tasted fine. What was it & why?

Brent knows his stuff! We are so sincerely sorry. When they bottled skim, dated 6/21, they did so after making cream (which is a big no no). There was still a little cream left in the filler and a small amount got into the skim. Over time it rose to the top of many bottles revealing its self. Cream is delicious in your coffee or when you're baking, but we do not want it in the skim milk. We offer a 100% guarantee on our product. We know you pay more for our milk and we always want to ensure you get your moneys worth. Please feel free to return to the store for a new bottle or to get your money back. Thank you for asking!

cream, It floats to the top in non homogenized milk and can solidify. Usually unplugging it and shaking it mixes it back up. Also skimming off the top as you did works to. I'm guessing even though you bought skim, there's enough cream percentage left to separate and plug the top of the bottle. I buy the cream line milk and there is usually a good solid plug of an inch or more. I believe it is due to not being homogenized the milkfat can separate from the milk.
