Grand Marnier Orange Liqueur Miniature - 5cl Grand Marnier only uses one specific variety of orange called Citrus Bigaradia. This is the richest in essential oils. These oranges are grown traditionally on a plantation in the Caribbean and when ripe are hand-picked. The orange peels are dried naturally in the sun and are then macerated and distilled to bring our their most purest essence. It is the combination of this aromatic elixir blended together with some of the finest French cognacs that is behind the world renowned orange liqueur.
