Living, organic ferments, handcrafted in Switzerland.

Brown mustard seed and a small dry and nervous grain. She makes it clear to us when we grind it freshly fermented and then over time it softens.

A new feat of fermentation. All the spiciness has disappeared, sweet notes, reminiscent of black garlic, are emerging…

Our Shiro Miso is clear, soft and slightly salty, with a nice roundness on the palate and almost caramelized notes that can recall salted butter. A real concentrate of umami.

An additional color to our rainbow of delights. Here is Spirulina Mustard, based on yellow mustard seeds, spirulina brings its little extra nutrition and a very interesting flavor.

Fermented mustard can be divisive, as the fermentation takes its flavors into territory not yet explored with sausages.


After testing them all, we created our own. It’s spicy without being too harsh, and your dishes will be begging for more.

The art of fermentation also incorporates zero waste, and here is one of its crown jewels.

A unique Fermentierra creation. More than just miso, almost a sauce, a condiment not to be missed.
