Apertifs are drinks served before a meal to stimulate the appetite. They can be alcoholic or non-alcoholic and are often enjoyed in social settings. Common types include vermouth, champagne, and bitters, each offering unique flavors that prepare the palate for the upcoming meal. Traditionally, aperitifs are served chilled or over ice, sometimes accompanied by small snacks like olives or nuts. The practice of enjoying an aperitif is popular in many cultures, particularly in France and Italy, where it is seen as a way to relax and socialize before dining.
