A white grape variety grown in Hungary and Slovakia and the main ingredient of Tokaji Aszú. It is an early budding late ripening variety and and is particularly susceptible to botrytis.
Its wines are characterised by their high alcohol levels (sometimes as much as 14%) and their high acidity - it is the latter which gives Tokaji wines their longevity. It is most commonly planted in the Tokaj-Hegyalja region and is usually blended with Harslevelu and sometimes Muscat to produce Tokaji Aszú. The grape is also grown widely to produce acidic but sturdy dry white wine.
