There are three varieties of Lillet: Rosé, Blanc and Rouge. The difference in colour and taste depends on the wine based used. Lillet Rosé calls for Merlot, Cabernet Sauvignon, and Sémillon bases; Lillet Blanc is made from a blend of Sauvignon Blanc and Semillon; and finally, Lillet Rouge sticks to Merlot and Cabernet Sauvignon.
