An
alcoholic drink. In the
Netherlands people drink 'Oranjebitter' on
Queens' day to celebrate the
birthday of their
queen.
The drink is brewed by many breweries in the Netherlands.
It's made by putting orange-peels in brandy. After a certain amount of time (differs) the brandy will turn orange and have a slight taste of orange.
The origin of the drink is unknown. It first appears in history in the 18th century when people who supported stadtholder Willem V (also known as "Willem van Oranje") dressed themselves with orange scars and drank 'Oranjebitter' in taverns.
The royal family of the Netherlands is related to Willem V. This is the reason why Dutch people still drink "Oranjebitter" on Queens' day. On this holiday you can often buy a small glass in churches and fill it with Oranjebitter at the top of the tower of that church.
(personal note: these towers often have winding staircases. These are quite hard to descent after drinking Oranjebitter...)
