This factory with a restaurant and museum produces Gruyere cheese, an AOP cheese with a guaranteed high quality.
There is an admission fee to enter the museum, but with your ticket you get a small pouch set of Gruyere cheeses to compare different tastings of 6, 8, and 10 months aged cheese, so it's a good deal.
The shop sells cheese and other Gruyere-related products, and you can enjoy cheese fondue in the restaurant. The factory is open only on weekday mornings, so if you want to see how cheese is made, try visiting during that time.
