The original Blue Curacao. Bols Blue was, and still is, the world’s best-selling blue curacao. Known in the previous century as “Crème de Ciel”, it is one of the oldest flavors in the modern Bols liqueur range. Bols Blue adds a sparkling blue color, a powerful orange flavor and a superb and unique aftertaste to any cocktail. As well as being a great substitute for Triple Sec in cocktails like the Blue Margarita and electric lemonade, it is also delicious when served long with soda or orange juice. Bols Blue not only offer color to a drink, but adds a rich, varied orange flavor from a special type of oranges and its peel. This gives Bols Blue a unique finish.
