Every year in summer, usually in June, when the St. John's wort is in full blossom, we open our production site in Kesswil to visitors. A guided tour through the production cycle allows visitors to observe our manufacturing process first-hand.
More information about the next Open Day and how to register for a guided tour can be found at the beginning of the year on our main page.
