Kaltbach cheeses are carefully crafted in the deep, cool Kaltbach Cave located in the Alpine Valley of Switzerland. The Kaltbach Cave is a 22 million-year-old natural sandstone labyrinth with a small tranquil river running through. In fact, Kaltbach means ‘cold river’ and it is what allows for a constant humidity of 96 percent in the mineral-rich cave air. This natural process regulates the humidity, which is a crucial part of the texture and flavor development and what makes this cheese unlike any other in the world. Kaltbach Le Gruyère® AOP matures peacefully under the watchful care of the Kaltbach Master Affineur in the cave. The mineral-rich air creates the perfect environment for transforming specially selected Le Gruyère wheels into wondrous depths of flavor. Each wheel is recognized instantly by the color of its rind – an unmistakable rustic brown patina -and its flavors of dried stone fruit, spice, black tea and hazelnuts with an earthy depth to captivate your taste buds. The texture is smooth with a slight flake and pronounced crystal crunch.
