Retter’s uncompromisingly closed food cycle is consistently implemented in their adjacent production plant, the Retter BioGut, and can be experienced transparently. Here, the fruits of the 4ha organic farm are refined into juice, distillates, jams and ice cream, as well as 100% of the bread and pastries needed daily in the hotel and organic shop freshly baked. Courses and lectures on sustainable living are held regularly for guests. In the restaurant kitchen, it is Retter’s commitment to use only animals organically raised outdoors within a maximum radius of 35 km. When processed 100% and the animal is used. Of course, Retter’s kitchen caters for vegans and vegetarians with a fine selection of ingredients.
