Furmint (also known as Mainak) is a white Hungarian wine grape variety that is most noted widely grown in the Tokaj-Hegyalja wine region where it is used to produce single-varietal dry wines as well as being the principal grape in the better known Tokaji dessert wines. It is also grown in the tiny Hungarian wine region of Somló. Furmint plays a similar role in the Slovakian wine region of Tokaj. It is also grown in Austria where it is known as Mosler. Smaller plantings are found in Slovenia where it is known as Šipon. The grape is also planted in Croatia & Serbia, where it is known as Moslavac. It is also found in Romania and in former republics of the Soviet Union. Furmint is a late ripening variety. For dry wines the harvest starts usually in September, however sweet wine specific harvest can start in the second half of October or even later, and is often affected by Botrytis.

The name Furmint may have been taken from the word froment for the wheat-gold color of the wine it produces. While it is possible that the grape was brought to Hungary in the 13th century during the reign of King Béla IV, ampelographers believe that the grape is likely native to the region.
