Muscadelle is a white grape variety originating in France, primarily grown in the wine regions of the Bassin Aquitaine. It is rarely used to make wine on its own and is often added as an accent to wines made from Semillon and Sauvignon.
In Australia, sweet fortified wines made from Muscadelle were traditionally known under the synonym "Tokay". However, since the use of the name "Tokay" is no longer permitted, these wines are now marketed under the name "Topaque".
