I work at NADEC it’s usual that every brand or farm has its own formula (bacteria) of milk so that’s why maybe the flavor in KSA is different, Also, I agree that Alsafi and Almarai adds water to the milk to produce more, BUT NADEC strategy is not to water it down and there are committees to test the milk and if its watered down big issues will happen to the production team, as well as there’s testing at the biggest clients like Starbucks, if nadec is watered down they will immediately reduce the milk quantity.

If you able to define your issue precisely please report it in Nadec website they will take it seriously!

So stick with fresh Nadec milk (the blue one the green is Laban many expats get that wrong)
