HerterWein makes consistent terroir wines that reflect the soil and the vintage, including people and animals. To achieve this, the winery has renounced everything that does not occur naturally since the very beginning: no chemical or synthetic PPPs, neither herbicides nor mineral fertilisers. Except for plant protection and grass cutting in the lower vineyards, the plots are cultivated by hand. The Taggenberg is streaked with red sandstone and limestone and has a lime-rich subsoil. The Chlimberg is rich in humus and fertile, whereas the Ödenhof is a rocky desert full of marl and gravel with lots of lime.
In the cellar, HerterWein vinifies using spontaneous fermentation without oenological aids from laboratories, pure yeast, enzymes or fining agents. In addition, HerterWein is involved in many projects for biodiversity in order to give back lost habitats to animals and to strengthen the terroir: Native woody plants, shrubs and other refuges for animals such as the wryneck, hoopoe and weasel can be found in the vines.
