The themed days take place in various buildings across the Swiss Open-Air Museum. Details can be found in the daily schedule.

4 / 5 October – Preserving Sauerkraut

At Ballenberg, at the start of autumn, the cooking team ferments a large pot of sauerkraut and look after it for 8 weeks. At the end of the season, this sauerkraut is ready and cooked for our guests in a historical kitchen. Our visitors have the opportunity to make their own sauerkraut.

Sauerkraut is a type of preservation technique in which food is preserved by means of lactic acid fermentation. Sauerkraut is not a vegetable as such, but is produced from white cabbage or cabbage. This vegetable with its long shelf-life and known worldwide for thousands of years, is the result of a natural fermentation process and salt.
