The white grape variety originates from Turkey; the name means "Grandfather Dede Beyazi". Synonyms are Ahmet Bey, Azeri, Yellow Hasandede, Hasan Dede, Hasandede, Khassandede and Sungurlu. Despite seemingly suggestive synonyms or morphological similarities, it should not be confused with the Kalecik Karasi or Sungurlu varieties. According to DNA analyses carried out in 2005, it is identical with the Azeri variety. Furthermore, a parent-offspring relationship to the no longer cultivated variety Sungurlu was found. There is also a red variety called Hasandede Siyahi; however, nothing is known about a possible genetic relationship. The medium-maturing vine is resistant to various vine diseases. It produces white wines of simple quality with high alcohol content, but is mainly used as table grape and for the production of pekmes(grape syrup). The variety is cultivated in the province of Kirikkale east of Ankara in central Anatolia. However, no stocks were reported in 2016 (Kym Anderson statistics).
