An apéritif is an alcoholic beverage usually served before a meal to stimulate the appetite, and is usually dry rather than sweet. Common choices for an apéritif are vermouth; champagne; pastis; gin; ouzo; fino, amontillado or other styles of dry sherry (but not usually cream or oloroso blended sherry, which is very sweet and rich).
An apéritif may be served with an hors d'oeuvre or amuse-bouche, such as crackers, cheese, pâté, quiche or olives.
Apéritif is a French word "derived from the Latin verb aperire, which means to open". The French colloquial word for apéritif is apéro.
