Determining the precise shelf life of yogurt is quite difficult as the expiration dates will differ greatly depending on the kinds of yogurt.

The following are some essential factors that you should consider when answering the question of how long does yogurt last:

  • The kinds of yogurt (for example, Greek yogurt, drinkable yogurt, and reduced-fat yogurt).
