A French aperitif wine. It is a blend of 85% Bordeaux wines (Sauvignon Blanc, Semillon and Muscadelle for the Blanc; Merlot and Cabernet Sauvignon for the Rouge) and 15% macerated liqueurs, mostly citrus liqueurs from the peels of sweet oranges from Spain and Morocco and the peels of bitter green oranges from Haiti. Lillet belongs in a family of aperitif known as tonic wines because of the addition of a liqueur of Chinchona bark from Peru which contains quinine. Lillet is matured in oak casks. While it has been produced since the late 19th century, the current formulation dates from 1986. The formulation was changed only to lower the sugar content; the level of quinine has remained roughly the same.
