Elderflower Liqueur is a sweet, floral alcoholic beverage made from the blossoms of the elderflower tree. It is typically produced by infusing the flowers in a base of alcohol, sugar, and water, resulting in a light, fragrant drink. The liqueur is often enjoyed in cocktails or as a refreshing aperitif. This liqueur is popular in various regions, particularly in Europe, where it is used in drinks like the Hugo cocktail or simply mixed with sparkling water. Its unique flavor profile makes it a versatile ingredient in both alcoholic and non-alcoholic beverages.
