This is an organic, concentrated cocktail mixer syrup from the Austrian brand Hoellinger, designed to replicate the complex bitter-sweet-herbal flavor of classic Italian aperitivi (like Aperol or Campari). It likely contains a blend of organic bitter herbs, citrus, and spices (such as gentian, orange, rhubarb) sweetened with organic sugar. Used to create non-alcoholic or alcoholic spritzes by mixing with sparkling water and prosecco or soda, offering a sophisticated pre-dinner drink.
