Why are some dates sweet and others not?

The sweetness of dates primarily depends on their variety and ripeness. Different types of dates, such as Medjool or Deglet Noor, have varying sugar content and flavor profiles. Additionally, the ripeness of the fruit affects its sweetness; fully ripe dates contain higher levels of natural sugars, while under-ripe ones may taste less sweet. Environmental factors, such as growing conditions and climate, also play a role in the sweetness of the dates.
