I'm curious -- I still buy Chobani and I still prefer it, but I've had what I consider to be a disappointing spoilage rate for unexpired yogurt (estimating 3-5%, for something I eat most days). Has anyone else had a similar experience? I realize I'm fishing for anecdata here, but I'd really like to know.
