This liqueur is a distillate of the dried peels of three types of oranges: curacao, a bitter orange from the Dutch Antilles, sweet oranges and mandarins. During the second distillation and other ingredients are added, including dried orange flowers and pennyroyal. The resultant spirit is then aged for 6 months in ash-wood white casks, filtered and sweetened. The finished product is clear, smooth and aromatically vibrant.
