The "apéritif" varies from region to region: Pastis is popular in the south of France, Crémant d'Alsace in the eastern region. Champagne can also be served. Kir, also called "Blanc-cassis", is a common and popular "apéritif"-cocktail made with a measure of "crème de cassis" (blackcurrant liqueur) topped up with white wine. The phrase "Kir Royal" is used when white wine is replaced with a "Champagne" wine. A simple glass of red wine, such as Beaujolais nouveau, can also be presented as an "apéritif", accompanied by "amuse-bouches". Some "apéritifs" can be fortified wines with added herbs, such as cinchona, gentian and vermouth. Trade names that sell well include Suze (the classic gentiane), Byrrh, Dubonnet, and Noilly Prat.
