Smederevka
Smederevka is a white wine grape variety grown in Serbia, Bulgaria and in the Tikveš wine-growing region of North Macedonia. The variety's name is derived from the name of Serbian city Smederevo. Most probably the growing of this grape variety started during the reign of Roman Emperor Marcus Aurelius Probus at the site called Mons Aureus [sr] on the right bank of river Danube near Smederevo. Smederevka is the 12th most planted grape variety in Serbia, with most planting being in the South Banat (47%) and Three Moravas (24,7%) wine regions. It is a high-yield grape with large, oval fruits in a conical cluster. The grape benefits from being cultivated in well-lit and ventilated conditions as it develops early but matures very late, around October. This is due to the fact that Smederevka grapes accumulate little sugar when ripening, especially so through intensive cultivation, which results in high levels of acidity in the grapes.
