This is the name commonly used by the European traders to classify dates that are neither Deglet nor Medjool. This group includes many varieties such as Kenta, Alligh, Sayer and Zahedi. The UK and Germany are the greatest importers of these dates. These dates are comparatively less priced than the high-quality dates such as Medjool and Deglet Nour.

Diversified and non-traditional varieties:

a. Medjool: This is one of the most expensive and popular varieties of dates. These dates are found in main European markets. Importing of Medjool dates is uncommon. The United States and Israel produce Medjool dates abundantly. In The United States, the date palm groves are located in California, to be specific, in the two areas of Bard valley and Coachella valley. They export the dates to European countries. Israelian Medjool dates are less expensive due to lower export costs.

Medjool dates come in three sizes: jumbo, large and medium(fancy). Medjool dates have the best degree of maturity and full flavor when it turns dark brown, almost black, and soft to the touch. They are called as 'queen of dates'.
