Liqueur Mandarin Castro. The refreshing, aromatic, fruity and delectable Mandarin Castro liqueur is produced from 100% natural mandarin peel extracts, in a traditional way. Even though the mandarin is a winter fruit, it provides the Mandarin Castro liqueur with a summer breeze that creates a delightful treat. This pleasant drink is recommended before or after meals, straight, on the rocks, with lemon or lime syrup or juice, combined with Mastiha Castro, Honey Castro, Vanilla Castro and Sage Castro liqueurs or with aged distilled spirits, such as Brandy Castro, or in cocktails.
