Several months ago, I ordered a yogurt culture and it made great yogurt for several batches, and then... the yogurt was thinner and runnier. I drain it to make Greek style, and even that wasn't as thick as before. I thought the culture had some kind of problem, so I planned to get new.
I made the next batch with store bought Greek yogurt, as I had before I bought the dried culture. Same result... thinner, runnier, and definitely bland! tasting. Ok, get another brand of yogurt to use as starter. Same thing. Another brand, same thing.
The commonality in all of this is the milk I've used. It finally occurred to me that they may be processing the milk differently!
My next batch will be with a different brand of milk.
