National Aperitif Day is celebrated annually on the third Thursday in May, with a focus on appreciating aperitifs, which are drinks taken before meals to stimulate the appetite. Originating in France, aperitifs are enjoyed globally and include options like fizz, dry vermouth, and white wine. They are often served at dinner parties, typically accompanied by light snacks, and can enhance the dining experience. Common aperitifs include Campari and Aperol, and they are usually presented with a slice of fruit. Celebrations may involve hosting dinner parties where guests begin their meals with aperitifs and can also include making and tasting various aperitif-based cocktails.
