Liqueur Bergamot Castro. Bergamot Castro is an aromatic, fruity, slightly bitter and assuredly enjoyable liqueur that stands out with its unique taste. It is produced from 100% natural bergamot peel extracts, in a traditional way. This pleasant drink can be drunk before or after meals, straight, on the rocks, in coffee, chocolate or tea, combined with Mastiha Castro, Honey Castro, Vanilla Castro and Sage Castro liqueurs or with aged distilled spirits, such as Brandy Castro, with fresh lemon or lime juice or in cocktails.
