Random yogurt question
 

I had a weird yogurt experience for me (a first in all of my years of eating yogurt): I opened up a cup of Trader Joe's European Style Chocolate Yogurt and it was completely liquefied. Not just a bit of liquid on top, but an entire cup of chocolatey liquid (the consistency of water, not drinkable yogurt). Anyone ever had this happen? Did I just get a cup of whey? And how does that make it through the manufacturing and packaging process?

Make your life easier. Just return it and move on.

I'm curious by nature.

My wife makes homemade yogurt all the time, what you describe is on the top of each new batch. It's like yogurt water, not tasty either. We drain that part because the yummy part is on the bottom.

I make homemade yogurt and it sounds like the batch you had may have had dead culture. I'd venture to guess that the batch got too hot during culturing and killed the bacteria.

Would that have caused it to liquefy after packaging? Or would it have never reached the yogurt stage?
