The authentically spicy Schabziger is unique and that’s exactly what makes a visit to the workshop of the company GESKA Inc. so interesting. The history of Switzerland’s oldest trademarked product began 550 years ago, on April 24, 1463. Zigermannli, the people who sold Schabziger from baskets carried on their backs, helped to make the cheese well known all over Switzerland, if not all over the world. Visitors learn about this and many other things during a tour of Glarus. Groups can book this tour.
