Did the formula change or is it a QC issue?

I used to love the Bai Molokai coconut. Now it seems like every other bottle tastes off and I have to pour it down the drain. At first I thought it was my taste buds, but I always open another bottle and it tastes fine. I’m not sure if these can go bad, or if the formula changed or what. I do know that I don’t like being unpleasantly surprised and wasting money. I’ll have to go back to drinking spring water. 🙁
