What type of grape is predominantly used in the production of Tokaji?

Furmint is the predominant grape used in the production of Tokaji, which is a famous Hungarian wine, particularly known for its sweet dessert wines. This grape variety is highly valued for its ability to develop noble rot, a crucial factor in the production of Tokaji Aszú, where the grapes are affected by the Botrytis cinerea fungus. This process concentrates the sugars and flavors in the grapes, which is essential for creating the rich, sweet profiles characteristic of Tokaji wines.

Furmint also contributes acidity, which balances the sweetness, a vital aspect for the overall structure and aging potential of the wine. While other grape varieties can be blended with Furmint in the production of Tokaji, such as Hárslevelü, Furmint remains the key and defining component of this celebrated wine.

In contrast, Chardonnay, Pinot Grigio, and Viognier are grapes that may be used in various wine regions around the world but do not play a primary role in Tokaji wine production. Each of these alternatives is associated with different styles and characteristics that do not reflect the specific profile of Tokaji wines.
