The Secret of Kaltbach

Our sandstone cave lies in a little village in Switzerland, nestled among rolling hills and fragrant meadows. This is where the best cheese becomes a KALTBACH. What does it need? A lot of peace and calm, loving attention and the unique and natural climate of our KALTBACH cave.

In KALTBACH's sandstone cave the conditions for the cheese to ripen are ideal, so that after several months the cheeses reach the perfect maturation point and develop their full character and dark-brown rind. This process is called cave refinement.

Only the very best cheese wheels from selected dairies are chosen for cave aging, where they are then carefully refined by our cave masters – until each cheese becomes a genuine culinary masterpiece. 

A Secret Technique

Refinement in the KALTBACH Cave

The conditions for cheese refinement are perfect in the KALTBACH cave. The humid mineral climate found 15m below the sandstone surface and the constant temperature provide the ideal conditions for the maturing process. The climate gives our cheeses their inimitable, distinctive aroma and texture as well as the rustic dark brown rind, typical for KALTBACH cheese.

The Maîtres-KALTBACH, also called KALTBACH cave masters are experts in the art of cheese refinement. They ensure the best conditions for the magic of the maturing process and care for each cheese – through brushing, salting and turning – with infinite passion and patience. Not every wine gets better when stored and the same goes for cheese: it is essential to go with your instinct on which cheese to select for cave refinement and how and when to take care of them over the maturation process.  

This feeling can’t be taught, but naturally develops after years of onsite experience. The art of cheese refinement in our cave is a secret technique that has never been written down, as the knowledge has been passed down from cave master to cave master and from one generation to the next for over 20 years.
