Customs duty and tax have always been an important issue for the distillers, as evidenced by the infamous spirits tax of 1507.
Here in the customs cellar, the Korn casks made from French Limousin oak, German oak and ash wood are kept behind bars and a customs officer closely monitors storage and retrieval in order to prevent smuggling. The bars could only be opened by two people at the same time: traditionally, the distiller had one key and the customs officer the other.
Today we have an open customs warehouse. Visitors can go straight to the casks where the Korn is maturing. But we still keep a careful eye on it, because these days the spirits tax rate is 13.03 Euro per litre of pure alcohol.
