described the famous wine of "Pedro Ximénez de Malaga". In 2007, DNA analysis showed that Pedro Ximénez was the offspring of the Arabic table grape Gibi which was once grown in southern France and throughout the Iberian peninsula, possibly introduced sometime during the Al-Andalus period of Moorish rule. Gibi was also discovered to be one of the parent varieties of the Extremadura wine grape Alarije, making the later variety a half-sibling to Pedro Ximénez. The origin of the name Pedro Ximénez is not yet clear with French ampelographer Joseph Roy-Chevrier speculating in 1905 that the grape was named after the village of Jiménez in Sanlúcar de Barrameda. As Ximénez and Jiménez are common surnames in Iberia, another theory is that the grape was named after a notable vintner who helped propagate the variety in the region. Viticulture Pedro Ximénez is a mid to late ripening grape variety that also tends to bud at the midpoint of the budding period of the vine growing season. The vine can be very vigorous and productive, producing large clusters of berries of irregular sizes (occasionally the result of millerandage). Despite having thin skinned berries, Pedro Ximénez is highly susceptible to the viticultural hazard of botrytis bunch rot as well as downy mildew, esca and eutypa dieback. The vine has some resistance to the fungal disease powdery mildew but is also very prone to damage caused by termite infection. Relationship and confusion with other grapes DNA evidence has shown that Pedro Ximénez is an offspring variety of the Arabic table grape Gibi and a half sibling to Alarije. In 2007, it was also confirmed that the table grape Corinto bianco was a seedless mutation of Pedro Ximénez. At one point it was thought that Pedro Ximénez was related (or possibly identical) to the German wine grapes Elbling and/or Riesling; but in addition to DNA evidence disproving a relationship, viticultural evidence had shown for many decades that Pedro Ximénez requires a much warmer climate than most German wine grapes in order to fully ripen, and was thus not likely to be closely related to any German wine variety. Other grapes that are sometimes confused with Pedro Ximénez include the Portuguese wine grape Galego Dourado, which shares several synonyms with Pedro Ximénez and was confused with the vine in South Africa, and the Argentine wine grape Pedro Giménez, which also shares several synonyms.
