Hopfengut Kaltenberg

The Tettnang Hop Estate celebrated its 160th. anniversary in 2004. It dates back to 1844 when the commercial cultivation of hops was begun by Johann Nepomuk Fidel von Lentz and the industrious citizens of Tettnang. In 1854 the hop cultivation area was 3 ha, in 1861, 91 ha, in 1874, 400 ha and in 1884, 648 ha. Hops were already in cultivation in the rest of Württemberg and were also important crops in the Rottenburg and Schwetzingen areas. There was at that time a brisk exchange of "cuttings" of the type named "Deutscher Frühhopfen" in those areas. Tettnang is nowadays the only surviving estate in Baden-Württemberg and is known worldwide as one of the leading suppliers of superior aromatic hops.

The development of the Tettnanger hops (in extracts). Detailed information can be found in the book "Grünes Gold" by Peter Heidtmann.
