Advocaat /ˈædvəkɑː/ or advocatenborrel is a traditional Dutch alcoholic beverage made from eggs, sugar, and brandy. The rich and creamy drink has a smooth, custard-like consistency. The typical alcohol content is generally between 14% and 20% ABV. Its contents may be a blend of egg yolks, aromatic spirits, sugar or honey, brandy, vanilla, and sometimes cream . Notable makers of advocaat include Warninks, Bols, Darna Ovo Liker, DeKuyper (in two varieties), and Verpoorten.[citation needed] Two theories have been put out on the origins of "advocaat".
