What is "dimiat"

Dimiat (; also romanized as Dimyat or Dimjat) is a white Bulgarian wine grape. It is one of Bulgaria's most widely planted white grape varieties, second only to Rkatsiteli. Wines made from this variety are noted for their perfume aromas. While some ampelographers believe that the variety is indigenous to Bulgaria, legends have developed around Dimiat being named after a town in the Nile Delta and was brought back to Europe by Crusaders in the Middle Ages.
