Shelf life refers to the period for storing a commodity before it begins to deteriorate or become unfit for consumption, use, or sale. The factors that influence the shelf life include the quality of raw materials, storage conditions, and manufacturing processes, among others. 

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).
  • Whether the yogurt contains preservatives.
  •  Storage conditions before you buy it.

The best period for consuming any kind of yogurt is the first week of shelf life. After this period, the reduction in quality of yogurt occurs.
