The Appenheimer Hundertgulden is a 56 hectare vineyard and the most famous single vineyard of the Appenheim community. The soil consists of limestone (Terra fusca), which originated from the coral banks of the Tertiary primeval sea. The Hundertgulden is the site with the highest carbonate content of all German vineyard sites. The current name was only given in the 14th century. At that time the site changed hands several times and large amounts of Rhenish gold guilders were paid for it.
